* feat(ui): add canvas project save/load (.invk format)
Add ZIP-based .invk file format to save and restore the entire canvas
state including all layers, masks, reference images, generation
parameters, LoRAs, and embedded image files. Images are deduplicated
on load - only missing images are re-uploaded from the project file.
- Always clear LoRAs on project load, even when project has none
- Fix jszip dependency ordering in package.json
- Add useAssertSingleton to SaveCanvasProjectDialog for consistency
- Add concurrency limit (max 5) for image fetch/upload requests
- Remove redundant deep-clone in remapCroppableImage (mutate in-place)
- Default project name to "Canvas Project" instead of empty string
* Chore pnpm fix
* feat(ui): group nodes by category in add-node dialog
Add collapsible category grouping to the node picker command palette.
Categories are parsed from the backend schema and displayed as
expandable sections with caret icons. All categories auto-expand
when searching.
* feat(ui): add toggle for category grouping in add-node dialog and prioritize exact matches
Add a persistent "Group Nodes by Category" setting to workflow editor settings,
allowing users to switch between grouped and flat node list views. Also sort
exact title matches to the top when searching.
* fix: update test schema categories to match expected templates
* feat: add expand/collapse all buttons to node picker and fix node categories
Add "Expand All" and "Collapse All" link-buttons above the grouped
category list in the add-node dialog so users can quickly open or
close all categories at once. Buttons are hidden during search since
categories auto-expand while searching.
Fix two miscategorized nodes: Z-Image ControlNet was in "Control"
instead of "Controlnet", and Upscale (RealESRGAN) was in "Esrgan"
instead of "Upscale".
* refactor(nodes): clean up node category taxonomy
Reorganize all built-in invocation categories into a consistent set of
18 groups (model, prompt, conditioning, controlnet_preprocessors,
latents, image, mask, inpaint, tiles, upscale, segmentation, math,
strings, primitives, batch, metadata, multimodal, canvas).
- Move denoise/i2l/l2i nodes consistently into "latents"
- Move all mask creation/manipulation nodes into "mask"
- Split ControlNet preprocessors out of "controlnet" into their own group
- Fold "unet", "vllm", "string", "ip_adapter", "t2i_adapter" into larger
groups
- Move metadata_linked denoise wrappers from "latents" to "metadata"
- Add missing category to ideal_size
- Introduce dedicated "canvas" group for canvas/output/panel nodes
Also adds the now-required `category` field to invocation template
fixtures in validateConnection.test.ts.

* fix: allow drag from shared boards to non-board targets (viewer, ref image, etc.)
Previously, images in shared boards owned by another user could not be
dragged at all — the draggable setup was completely skipped in
GalleryImage.tsx when canWriteImages was false. This blocked ALL drop
targets including the viewer, reference image pane, and canvas.
Now images are always draggable. The board-move restriction is enforced
in the dnd target isValid functions instead:
- addImageToBoardDndTarget: rejects moves from shared boards the user
doesn't own (unless admin or board is public)
- removeImageFromBoardDndTarget: same check
Other drop targets (viewer, reference images, canvas, comparison, etc.)
remain fully functional for shared board images.

* fix(security): add auth requirement to all sensitive routes in multimodal mode
* chore(backend): ruff
* fix (backend): improve user isolation for session queue and recall parameters
- Sanitize session queue information of all cross-user fields except for the timestamps and status.
- Recall parameters are now user-scoped.
- Queue status endpoints now report user-scoped activity rather than global activity
- Tests added:
TestSessionQueueSanitization (4 tests):
1. test_owner_sees_all_fields - Owner sees complete queue item data
2. test_admin_sees_all_fields - Admin sees complete queue item data
3. test_non_owner_sees_only_status_timestamps_errors -
Non-owner sees only item_id, queue_id, status, and timestamps; everything else is redacted
4. test_sanitization_does_not_mutate_original - Sanitization doesn't modify the original object
TestRecallParametersIsolation (2 tests):
5. test_user1_write_does_not_leak_to_user2 - User1's recall params are not visible in user2's client state
6. test_two_users_independent_state - Both users can write recall params independently without overwriting each other
fix(backend): queue status endpoints report user-scoped stats rather than global stats
* fix(workflow): do not filter default workflows in multiuser mode
Problem: When categories=['user', 'default'] (or no category filter)
and user_id was set for multiuser scoping, the SQL query became
WHERE category IN ('user', 'default') AND user_id = ?,
which excluded default workflows (owned by "system").
Fix: Changed user_id = ? to (user_id = ? OR category = 'default') in
all 6 occurrences across workflow_records_sqlite.py — in get_many,
counts_by_category, counts_by_tag, and get_all_tags. Default
workflows are now always visible regardless of user scoping.
Tests added (2):
- test_default_workflows_visible_when_listing_user_and_default — categories=['user','default'] includes both
- test_default_workflows_visible_when_no_category_filter — no filter still shows defaults
* fix(multiuser): scope queue/recall/intermediates endpoints to current user
Several read-only and event-emitting endpoints were leaking aggregate
cross-user activity in multiuser mode:
- recall_parameters_updated event was broadcast to every queue
subscriber. Added user_id to the event and routed it to the owner +
admin rooms only.
- get_queue_status, get_batch_status, counts_by_destination and
get_intermediates_count now scope counts to the calling user
(admins still see global state). Removed the now-redundant
user_pending/user_in_progress fields and simplified QueueCountBadge.
- get_queue_status hides current item_id/session_id/batch_id when the
current item belongs to another user.
Also fixes test_session_queue_sanitization assertions that lagged
behind the recently expanded redaction set.

* chore(backend): ruff
* fix(multiuser): reject anonymous websockets and scope queue item events
Close three cross-user leaks in the websocket layer:
- _handle_connect() now rejects connections without a valid JWT in
multiuser mode (previously fell through to user_id="system"), so
anonymous clients can no longer subscribe to queue rooms and observe
other users' activity. In single-user mode it still accepts as system
admin.
- _handle_sub_queue() no longer silently falls back to the system user
for an unknown sid in multiuser mode; it refuses the subscription.
- QueueItemStatusChangedEvent and BatchEnqueuedEvent are now routed to
user:{user_id} + admin rooms instead of the full queue room. Both
events carry unsanitized user_id, batch_id, origin, destination,
session_id, and error metadata and must not be broadcast.
- BatchEnqueuedEvent gains a user_id field; emit_batch_enqueued and
enqueue_batch thread it through.
New TestWebSocketAuth suite covers connect accept/reject for both
modes, sub_queue refusal, and private routing of the queue item and
batch events (plus a QueueClearedEvent sanity check).

* fix(multiuser): verify user record on websocket connect
A deleted or deactivated user with an unexpired JWT could still open a
websocket and subscribe to queue rooms. Now _handle_connect() checks the
backing user record (exists + is_active) in multiuser mode, mirroring
the REST auth path in auth_dependencies.py. Fails closed if the user
service is unavailable.
Tests: added deleted-user and inactive-user rejection tests; updated
valid-token test to create the user in the database first.

* fix(multiuser): close bulk download cross-user exfiltration path
Backend:
- POST /download now validates image read access (per-image) and board
read access (per-board) before queuing the download.
- GET /download/{name} is intentionally unauthenticated because the
browser triggers it via <a download> which cannot carry Authorization
headers. Access control relies on POST-time checks, UUID filename
unguessability, private socket event routing, and single-fetch deletion.
- Added _assert_board_read_access() helper to images router.
- Threaded user_id through bulk download handler, base class, event
emission, and BulkDownloadEventBase so events carry the initiator.
- Bulk download service now tracks download ownership via _download_owners
dict (cleaned up on delete).
- Socket bulk_download room subscription restricted to authenticated
sockets in multiuser mode.
- Added error-catching in FastAPIEventService._dispatch_from_queue to
prevent silent event dispatch failures.
Frontend:
- Fixed pre-existing race condition where the "Preparing Download" toast
from the POST response overwrote the "Ready to Download" toast from the
socket event (background task completes in ~17ms, so the socket event
can arrive before Redux processes the HTTP response). Toast IDs are now
distinct: "preparing:{name}" vs "{name}".
- bulk_download_complete/error handlers now dismiss the preparing toast.
Tests (8 new):
- Bulk download by image names rejected for non-owner (403)
- Bulk download by image names allowed for owner (202)
- Bulk download from private board rejected (403)
- Bulk download from shared board allowed (202)
- Admin can bulk download any images (202)
- Bulk download events carry user_id
- Bulk download event emitted to download room
- GET /download unauthenticated returns 404 for unknown files

* fix(multiuser): enforce board visibility on image listing endpoints
GET /api/v1/images?board_id=... and GET /api/v1/images/names?board_id=...
passed board_id directly to the SQL layer without checking board
visibility. The SQL only applied user_id filtering for board_id="none"
(uncategorized images), so any authenticated user who knew a private
board ID could enumerate its images.
Both endpoints now call _assert_board_read_access() before querying,
returning 403 unless the caller is the board owner, an admin, or the
board is Shared/Public.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* chore(backend): ruff
* fix(multiuser): require image ownership when adding images to boards
add_image_to_board and add_images_to_board only checked write access to
the destination board, never verifying that the caller owned the source
image. An attacker could add a victim's image to their own board, then
exploit the board-ownership fallback in _assert_image_owner to gain
delete/patch/star/unstar rights on the image.
Both endpoints now call _assert_image_direct_owner which requires direct
image ownership (image_records.user_id) or admin — board ownership is
intentionally not sufficient, preventing the escalation chain.
Also fixed a pre-existing bug where HTTPException from the inner loop in
add_images_to_board was caught by the outer except-Exception and returned
as 500 instead of propagating the correct status code.

* chore(backend): ruff
* fix(multiuser): validate image access in recall parameter resolution
The recall endpoint loaded image files and ran ControlNet preprocessors
on any image_name supplied in control_layers or ip_adapters without
checking that the caller could read the image. An attacker who knew
another user's image UUID could extract dimensions and, for supported
preprocessors, mint a derived processed image they could then fetch.
Added _assert_recall_image_access() which validates read access for every
image referenced in the request before any resolution or processing
occurs. Access is granted to the image owner, admins, or when the image
sits on a Shared/Public board.

* fix(multiuser): require admin auth on model install job endpoints
list_model_installs, get_model_install_job, pause, resume,
restart_failed, and restart_file were unauthenticated — any caller who
could reach the API could view sensitive install job fields (source,
local_path, error_traceback) and interfere with installation state.
All six endpoints now require AdminUserOrDefault, consistent with the
neighboring cancel and prune routes.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(multiuser): close bulk download exfiltration and additional review findings
Bulk download capability token exfiltration:
- Socket events now route to user:{user_id} + admin rooms instead of the
shared 'default' room (the earlier toast race that blocked this approach
was fixed in a prior commit).
- GET /download/{name} re-requires CurrentUserOrDefault and enforces
ownership via get_owner().
- Frontend download handler replaced <a download> (which cannot carry auth
headers) with fetch() + Authorization header + programmatic blob download.
Additional fixes from reviewer tests:
- Public boards now grant write access in _assert_board_write_access and
mutation rights in _assert_image_owner (BoardVisibility.Public).
- Uncategorized image listing (GET /boards/none/image_names) now filters
to the caller's images only, preventing cross-user enumeration.
- board_images router uses board_image_records.get_board_for_image()
instead of images.get_dto() to avoid dependency on image_files service.

* fix(multiuser): add user_id scoping to workflow SQL mutations
Defense-in-depth: the route layer already checks ownership before
calling update/delete/update_is_public/update_opened_at, but the SQL
statements did not include AND user_id = ?, so a bypass of the route
check would allow cross-user mutations.
All four methods now accept an optional user_id parameter. When
provided, the SQL WHERE clause is scoped to that user. The route layer
passes current_user.user_id for non-admin callers and None for admins.

* fix(multiuser): allow non-owner uploads to public boards
upload_image() blocked non-owner uploads even to public boards. The
board write check now allows uploads when board_visibility is Public,
consistent with the public-board semantics in _assert_board_write_access
and _assert_image_owner.

* feat: add configurable shift parameter for Z-Image sigma schedule
Add a shift (mu) override to the Z-Image denoise invocation and expose
it in the UI. When left blank, shift is auto-calculated from image
dimensions (existing behavior). Users can override to fine-tune the
timestep schedule, with an inline X button to reset back to auto.
* refactor: switch Z-Image sigma schedule from exponential to linear time shift
Use shift directly as a linear multiplier instead of exp(mu), giving
more predictable and uniform control over the timestep schedule.
Auto-calculated values are converted via exp(mu) to preserve identical
default behavior.
* feat: recall Z-Image shift parameter from metadata
Write z_image_shift into graph metadata and add a ZImageShift recall
handler so the shift override can be restored from previously generated
images. Auto-mode (null) is omitted from metadata to avoid persisting a
stale value.

* feat: Add canvas-workflow integration feature
This commit implements a new feature that allows users to run workflows
directly from the unified canvas. Users can now:
- Access a "Run Workflow" option from the canvas layer context menu
- Select a workflow with image parameters from a modal dialog
- Customize workflow parameters (non-image fields)
- Execute the workflow with the current canvas layer as input
- Have the result automatically added back to the canvas
Key changes:
- Added canvasWorkflowIntegrationSlice for state management
- Created CanvasWorkflowIntegrationModal and related UI components
- Added context menu item to raster layers
- Integrated workflow execution with canvas image extraction
- Added modal to global modal isolator
This integration enhances the canvas by allowing users to leverage
custom workflows for advanced image processing directly within the
canvas workspace.
Implements feature request for deeper workflow-canvas integration.
* refactor(ui): simplify canvas workflow integration field rendering
- Extract WorkflowFieldRenderer component for individual field rendering
- Add WorkflowFormPreview component to handle workflow parameter display
- Remove workflow compatibility filtering - allow all workflows
- Simplify workflow selector to use flattened workflow list
- Add comprehensive field type support (String, Integer, Float, Boolean, Enum, Scheduler, Board, Model, Image, Color)
- Implement image field selection UI with radio
* feat(ui): add canvas-workflow-integration logging namespace
* feat(ui): add workflow filtering for canvas-workflow integration
- Add useFilteredWorkflows hook to filter workflows with ImageField inputs
- Add workflowHasImageField utility to check for ImageField in Form Builder
- Only show workflows that have Form Builder with at least one ImageField
- Add loading state while filtering workflows
- Improve error messages to clarify Form Builder requirement
- Update modal description to mention Form Builder and parameter adjustment
- Add fallback error message for workflows without Form Builder
* feat(ui): add persistence and migration for canvas workflow integration state
- Add _version field (v1) to canvasWorkflowIntegrationState for future migrations
- Add persistConfig with migration function to handle version upgrades
- Add persistDenylist to exclude transient state (isOpen, isProcessing, sourceEntityIdentifier)
- Use es-toolkit isPlainObject and tsafe assert for type-safe migration
- Persist selectedWorkflowId and fieldValues across sessions
* pnpm fix imports
* fix(ui): handle workflow errors in canvas staging area and improve form UX
- Clear processing state when workflow execution fails at enqueue time
or during invocation, so the modal doesn't get stuck
- Optimistically update listAllQueueItems cache on queue item status
changes so the staging area immediately exits on failure
- Clear processing state on invocation_error for canvas workflow origin
- Auto-select the only unfilled ImageField in workflow form
- Fix image field overflow and thumbnail sizing in workflow form
* feat(ui): add canvas_output node and entry-based staging area
Add a dedicated `canvas_output` backend invocation node that explicitly
marks which images go to the canvas staging area, replacing the fragile
board-based heuristic. Each `canvas_output` node produces a separate
navigable entry in the staging area, allowing workflows with multiple
outputs to be individually previewed and accepted.
Key changes:
- New `CanvasOutputInvocation` backend node (canvas.py)
- Entry-based staging area model where each output image is a separate
navigable entry with flat next/prev cycling across all items
- Frontend execute hook uses `canvas_output` type detection instead of
board field heuristic, with proper board field value translation
- Workflow filtering requires both Form Builder and canvas_output node
- Updated QueueItemPreviewMini and StagingAreaItemsList for entries
- Tests for entry-based navigation, multi-output, and race conditions
* Chore pnp run fix
* Chore eslint fix
* Remove unused useOutputImageDTO export to fix knip lint

Klein 9B Base (undistilled) and Klein 9B (distilled) have identical
architectures and cannot be distinguished from the state dict alone.
Use a filename heuristic ("base" in the name) to detect the Base
variant for checkpoint, GGUF, and diffusers format models.
Also fixes the incorrect guidance_embeds-based detection for diffusers
format, since both variants have guidance_embeds=False.
* feat: add support for OneTrainer BFL Flux LoRA format
Newer versions of OneTrainer export Flux LoRAs using BFL internal key
names (double_blocks, single_blocks, img_attn, etc.) with a
'transformer.' prefix and split QKV projections (qkv.0/1/2, linear1.0/1/2/3).
This format was not recognized by any existing detector.
Add detection and conversion for this format, merging split QKV and
linear1 layers into MergedLayerPatch instances for the fused BFL model.
* chore ruff
OneTrainer exports Z-Image LoRAs with 'transformer.layers.' key prefix
instead of 'diffusion_model.layers.'. Add this prefix (and the
PEFT-wrapped 'base_model.model.transformer.layers.' variant) to the
Z-Image LoRA probe so these models are correctly identified and loaded.
- Add missing aspect ratios (4:5, 5:4, 8:1, 4:1, 1:4, 1:8) to type
system for external model support
- Sync canvas bbox when external model resolution preset is selected
- Use params preset dimensions in buildExternalGraph to prevent
"unsupported aspect ratio" errors
- Lock all bbox controls (resize handles, aspect ratio select,
width/height sliders, swap/optimal buttons) for external models
with fixed dimension presets
- Disable denoise strength slider for external models (not applicable)
- Sync bbox aspect ratio changes back to paramsSlice for external models
- Initialize bbox dimensions when switching to an external model
* Added If node

* feat(nodes): make if-node type checks cardinality-aware without loosening global AnyField
* chore: typegen

* bugfix(multiuser): ask user to log back in when authentication token expires
* feat: sliding window session expiry with token refresh
Backend:
- SlidingWindowTokenMiddleware refreshes JWT on each mutating request
(POST/PUT/PATCH/DELETE), returning a new token in X-Refreshed-Token
response header. GET requests don't refresh (they're often background
fetches that shouldn't reset the inactivity timer).
- CORS expose_headers updated to allow X-Refreshed-Token.
Frontend:
- dynamicBaseQuery picks up X-Refreshed-Token from responses and
updates localStorage so subsequent requests use the fresh expiry.
- 401 handler only triggers sessionExpiredLogout when a token was
actually sent (not for unauthenticated background requests).
- ProtectedRoute polls localStorage every 5s and listens for storage
events to detect token removal (e.g. manual deletion, other tabs).
Result: session expires after TOKEN_EXPIRATION_NORMAL (1 day) of
inactivity, not a fixed time after login. Any user-initiated action
resets the clock.

* chore(backend): ruff
* fix: address review feedback on auth token handling
Bug fixes:
- ProtectedRoute: only treat 401 errors as session expiry, not
transient 500/network errors that should not force logout
- Token refresh: use explicit remember_me claim in JWT instead of
inferring from remaining lifetime, preventing silent downgrade of
7-day tokens to 1-day when <24h remains
- TokenData: add remember_me field, set during login
Tests (6 new):
- Mutating requests (POST/PUT/DELETE) return X-Refreshed-Token
- GET requests do not return X-Refreshed-Token
- Unauthenticated requests do not return X-Refreshed-Token
- Remember-me token refreshes to 7-day duration even near expiry
- Normal token refreshes to 1-day duration
- remember_me claim preserved through refresh cycle

* feat: add bulk reidentify action for models (#8951)
Add a "Reidentify Models" bulk action to the model manager, allowing
users to re-probe multiple models at once instead of one by one.
- Backend: POST /api/v2/models/i/bulk_reidentify endpoint with partial
failure handling (returns succeeded/failed lists)
- Frontend: bulk reidentify mutation, confirmation modal with warning
about custom settings reset, toast notifications for all outcomes
- i18n: new translation keys for bulk reidentify UI strings
* fix typgen
* Fix bulk reidentify failing for models without trigger_phrases
The bulk reidentify endpoint was directly assigning trigger_phrases
without checking if the config type supports it, causing an
AttributeError for ControlNet models. Added the same hasattr guard
used by the individual reidentify endpoint. Also restored the
missing path preservation that the individual endpoint has.
Add AlibabaCloudProvider supporting Qwen Image and Wan model families
via the DashScope API. Includes sync (multimodal-generation) and async
(image-generation with task polling) request modes, five starter models
(Qwen Image 2.0 Pro, 2.0, Max, Wan 2.6 T2I, Qwen Image Edit Max),
config fields for API key and base URL, and frontend registration.
- Remove negative_prompt, steps, guidance, reference_image_weights,
reference_image_modes from external model nodes (unused by any provider)
- Remove supports_negative_prompt, supports_steps, supports_guidance
from ExternalModelCapabilities
- Add provider_options dict to ExternalGenerationRequest for
provider-specific parameters
- Add OpenAI-specific fields: quality, background, input_fidelity
- Add Gemini-specific fields: temperature, thinking_level
- Add new OpenAI starter models: GPT Image 1.5, GPT Image 1 Mini,
DALL-E 3, DALL-E 2
- Fix OpenAI provider to use output_format (GPT Image) vs
response_format (DALL-E) and send model ID in requests
- Add fixed aspect ratio sizes for OpenAI models (bucketing)
- Add ExternalProviderRateLimitError with retry logic for 429 responses
- Add provider-specific UI components in ExternalSettingsAccordion
- Simplify ParamSteps/ParamGuidance by removing dead external overrides
- Update all backend and frontend tests
Add combined resolution preset selector for external models that maps
aspect ratio + image size to fixed dimensions. Gemini 3 Pro and 3.1 Flash
now send imageConfig (aspectRatio + imageSize) via generationConfig instead
of text-based aspect ratio hints used by Gemini 2.5 Flash.
Backend: ExternalResolutionPreset model, resolution_presets capability field,
image_size on ExternalGenerationRequest, and Gemini provider imageConfig logic.
Frontend: ExternalSettingsAccordion with combo resolution select, dimension
slider disabling for fixed-size models, and panel schema constraint wiring
for Steps/Guidance/Seed controls.
Add 'external', 'external_image_generator', and 'external_api' to Zod
enum schemas (zBaseModelType, zModelType, zModelFormat) to match the
generated OpenAPI types. Remove redundant union workarounds from
component prop types and Record definitions.
Fix type errors in ModelEdit (react-hook-form Control invariance),
parsing.tsx (model identifier narrowing), buildExternalGraph (edge
typing), and ModelSettings import/export buttons.
Move external_gemini_base_url and external_openai_base_url into
api_keys.yaml alongside the API keys so all external provider config
lives in one dedicated file, separate from invokeai.yaml.

* Fix MPS device assertion in repair test
* fix(ui): resolve models by name+base+type when recalling metadata for reinstalled models
When a model (IP Adapter, ControlNet, etc.) is deleted and reinstalled,
it gets a new UUID key. Previously, metadata recall would fail because
it only looked up models by their stored UUID key. Now the recall falls
back to searching by name+base+type, allowing reinstalled models with
the same name to be correctly resolved.
https://claude.ai/code/session_01XYubzMK363BXGTvfJJqFnX
* Add hash-based model recall fallback for reinstalled models
When a model is deleted and reinstalled, it gets a new UUID key but
retains the same BLAKE3 content hash. This adds hash as a middle
fallback stage in model resolution (key → hash → name+base+type),
making recall more robust.
Changes:
- Add /api/v2/models/get_by_hash backend endpoint (uses existing
search_by_hash from model records store)
- Add getModelConfigByHash RTK Query endpoint in frontend
- Add hash fallback to both resolveModel and parseModelIdentifier

When deleting a file-based model (e.g. LoRA), the previous logic used
rmtree on the parent directory, which would delete all files in that
folder — even unrelated ones. Now only the specific model file is
removed, and the parent directory is cleaned up only if empty afterward.
* feat: add strict_password_checking config option to relax password requirements
- Add `strict_password_checking: bool = Field(default=False)` to InvokeAIAppConfig
- Add `get_password_strength()` function to password_utils.py (returns weak/moderate/strong)
- Add `strict_password_checking` field to SetupStatusResponse API endpoint
- Update users_base.py and users_default.py to accept `strict_password_checking` param
- Update auth.py router to pass config.strict_password_checking to all user service calls
- Create shared frontend utility passwordUtils.ts for password strength validation
- Update AdministratorSetup, UserProfile, UserManagement components to:
- Fetch strict_password_checking from setup status endpoint
- Show colored strength indicators (red/yellow/blue) in non-strict mode
- Allow any non-empty password in non-strict mode
- Maintain strict validation behavior when strict_password_checking=True
- Update SetupStatusResponse type in auth.ts endpoint
- Add passwordStrength and passwordHelperRelaxed translation keys to en.json
- Add tests for new get_password_strength() function

Fix graceful shutdown to wait for download/install worker threads (#102)
* Initial plan
* Replace os._exit(0) with ApiDependencies.shutdown() on KeyboardInterrupt
Instead of immediately force-exiting the process on CTRL+C, call
ApiDependencies.shutdown() to gracefully stop the download and install
manager services, allowing active work to complete or cancel cleanly
before the process exits.
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Make stop() idempotent in download and model install services
When CTRL+C is pressed, uvicorn's graceful shutdown triggers the FastAPI
lifespan which calls ApiDependencies.shutdown(), then a KeyboardInterrupt
propagates from run_until_complete() hitting the except block which tries
to call ApiDependencies.shutdown() a second time.
Change both stop() methods to return silently (instead of raising) when
the service is not running. This handles:
- Double-shutdown: lifespan already stopped the services
- Early interrupt: services were never fully started

* feat(model_manager): add export/import for model settings
Add the ability to export model settings (default_settings, trigger_phrases,
cpu_only) as JSON and import them back. The model name is used as the
filename for exports.
https://claude.ai/code/session_01LXKjbRjfzcG3d3vzk3xRCh
* fix(ui): reset settings forms after import so updated values display immediately
The useForm defaultValues only apply on mount, so importing model settings
updated the backend but the forms kept showing stale values. Added useEffect
to reset forms when the underlying model config changes. Also fixed lint
errors (strict equality, missing React import).
* fix(ui): harden model settings export/import
Prevent cross-model-type import errors by filtering imported fields
against the target model's supported fields, showing clear warnings
for incompatible or partially compatible settings instead of raw
pydantic validation errors. Also fix falsy checks for empty arrays
and objects in export, disable export button when nothing to export,
add client-side validation and FileReader error handling on import.

Merged Z-Image checkpoints (e.g. models with LoRAs baked in) may bundle
text encoder weights (text_encoders.*) or other non-transformer keys
alongside the transformer weights. These cause load_state_dict() to fail
with strict=True. Instead of disabling strict mode, explicitly whitelist
valid ZImageTransformer2DModel key prefixes and discard everything else.
Also moves RAM allocation after filtering so it doesn't over-allocate
for discarded keys.

Add board isolation issue specification document
Document the three board isolation issues that need to be addressed:
1. Board list not updating when switching users
2. "Uncategorized" board shared among users
3. Admin cannot access all users' boards
Includes technical details, implementation plan, and acceptance criteria.
This document will be used to create a separate GitHub issue and PR.

Fix test failures in Phase 7 tests
- Fix board service API calls to use enum values (BoardRecordOrderBy, SQLiteDirection) instead of strings
- Fix board deletion test to use get_dto() instead of non-existent get() method
- Add exception handling to verify_password() for invalid hash formats
- Update SQL injection test to accept both 401 and 422 status codes (Pydantic validation)
All fixes ensure tests match actual API signatures and handle edge cases properly.

Fix token forgery test to properly decode and modify JWT payload
The test was attempting to modify the JWT payload by string replacement on the
base64-encoded data, which doesn't work since "false" doesn't appear literally
in the base64 encoding. Fixed to:
- Properly decode the base64 payload
- Parse the JSON
- Modify the is_admin field
- Re-encode the payload
- Create a forged token with the modified payload and original signature
- Verify it's rejected with 401 status
This properly tests that JWT signature verification prevents token forgery.

Fix test_verify_expired_token timing issue
Increased token expiration from 10ms to 100ms and wait time from 20ms to 200ms
to make the test more reliable. The previous timing was too tight and could
cause race conditions where the token hadn't actually expired yet when verified.
This ensures the test reliably validates that expired tokens are properly rejected.

Fix token verification to properly validate signatures and expiration
The verify_token() function was not explicitly enabling JWT verification options,
causing it to accept expired tokens and tokens with modified signatures/payloads.
Fixed by explicitly setting verification options:
- verify_signature: True (reject modified tokens)
- verify_exp: True (reject expired tokens)
- verify_nbf: True (verify "not before" claim)
- verify_iat: True (verify "issued at" claim)
- verify_aud: False (we don't use audience claims)
Also added catch-all exception handler for other validation errors.
This ensures all token security tests pass properly.

Revert to default python-jose verification behavior
Removed explicit options parameter from jwt.decode() call since python-jose
verifies signatures and expiration by default. The explicit options may have
been causing issues or conflicts with the library's default behavior.
Added comments clarifying that python-jose defaults are secure and handle
verification properly. Need user to test and provide debugging output if
issues persist.

Fix JWT expiration verification for python-jose 3.5.0
python-jose 3.5.0 has a bug where expiration verification doesn't work properly
by default. The jwt.decode() function is not rejecting expired tokens even when
they should be rejected.
Workaround implemented:
1. First, get unverified claims to extract the 'exp' timestamp
2. Manually check if current time >= exp time (token is expired)
3. Return None immediately if expired
4. Then verify signature with jwt.decode() for tokens that aren't expired
This ensures:
- Expired tokens are properly rejected
- Signature verification still happens for non-expired tokens
- Modified tokens are rejected due to signature mismatch
All three failing tests should now pass:
- test_verify_expired_token
- test_verify_token_with_modified_payload
- test_token_signature_verification
Co-authored-by: lstein <111189+lstein@users.noreply.github.com>
* Fix race condition in token verification - verify signature before expiration
Changed the order of verification in verify_token():
1. First verify signature with jwt.decode() - rejects modified/forged tokens
2. Then manually check expiration timestamp
Previous implementation checked expiration first using get_unverified_claims(),
which could cause a race condition where:
- Token with valid payload but INVALID signature would pass expiration check
- If expiration check happened to return None due to timing, signature was never verified
- Modified tokens could be accepted intermittently
New implementation ensures signature is ALWAYS verified first, preventing any
modified tokens from being accepted, while still working around the python-jose
3.5.0 expiration bug by manually checking expiration after signature verification.
This eliminates the non-deterministic test failures in test_verify_token_with_modified_payload.

* Fix BFL→diffusers key mapping for non-block layers in FLUX.2 LoRA/LoKR
BFL's FLUX.2 model uses different names than diffusers' Flux2Transformer2DModel
for top-level modules (embedders, modulations, output layers). The existing
conversion only handled block-level renames (double_blocks→transformer_blocks),
causing "Failed to find module" warnings for non-block LoRA keys like img_in,
txt_in, modulation.lin, time_in, and final_layer.

* WIP: Add FLUX.2 Klein LoRA support (BFL PEFT format)
Initial implementation for loading and applying LoRA models trained
with BFL's PEFT format for FLUX.2 Klein transformers.
Changes:
- Add LoRA_Diffusers_Flux2_Config and LoRA_LyCORIS_Flux2_Config
- Add BflPeft format to FluxLoRAFormat taxonomy
- Add flux_bfl_peft_lora_conversion_utils for weight conversion
- Add Flux2KleinLoraLoaderInvocation node
Status: Work in progress - not yet fully tested

* feat(flux2): add LoRA support for FLUX.2 Klein models
Add BFL PEFT LoRA support for FLUX.2 Klein, including runtime conversion
of BFL-format keys to diffusers format with fused QKV splitting, improved
detection of Klein 4B LoRAs via MLP ratio check, and frontend graph wiring.
* feat(flux2): detect Klein LoRA variant (4B/9B) and filter by compatibility
Auto-detect FLUX.2 Klein LoRA variant from tensor dimensions during model
probe, warn on variant mismatch at load time, and filter the LoRA picker
to only show variant-compatible LoRAs.
* Chore Ruff
* Chore pnpm
* Fix detection and loading of 3 unrecognized Flux.2 Klein LoRA formats
Three Flux.2 Klein LoRAs were either unrecognized or misclassified due to
format detection gaps:
1. PEFT-wrapped BFL format (base_model.model.* prefix) was not recognized
because the detector only accepted the diffusion_model.* prefix.
2. Klein 4B LoRAs with hidden_size=3072 were misidentified as Flux.1 due to
a break statement exiting the detection loop before txt_in/vector_in
dimensions could be checked.
3. Flux2 native diffusers format (to_qkv_mlp_proj, ff.linear_in) was not
detected because the detector only checked for Flux.1 diffusers keys.
Also handles mixed PEFT/standard LoRA suffix formats within the same file.

Replace bare `except:` with `except Exception:` in sqlite_database.py
and mlsd/utils.py to avoid catching KeyboardInterrupt and SystemExit,
which can prevent graceful shutdowns and mask critical errors (PEP 8

Replace mutable default arguments (lists) with None in
imwatermark/vendor.py to prevent shared state between calls, which
is a known Python gotcha that can cause subtle bugs when default
mutable objects are modified in place.
* add tests for mutable defaults and bare except fixes
* Simplify exception propagation tests

* feat(z-image): add Z-Image Base (undistilled) model variant support
- Add ZImageVariantType enum with 'turbo' and 'zbase' variants
- Auto-detect variant on import via scheduler_config.json shift value (3.0=turbo, 6.0=zbase)
- Add database migration to populate variant field for existing Z-Image models
- Re-add LCM scheduler with variant-aware filtering (LCM hidden for zbase)
- Auto-reset scheduler to Euler when switching to zbase model if LCM selected
- Update frontend to show/hide LCM option based on model variant
- Add toast notification when scheduler is auto-reset
Z-Image Base models are undistilled and require more steps (28-50) with higher
guidance (3.0-5.0), while Z-Image Turbo is distilled for ~8 steps with CFG 1.0.
LCM scheduler only works with distilled (Turbo) models.
* Chore ruff format
* Chore fix windows path
* feat(z-image): filter LoRAs by variant compatibility and warn on mismatch
LoRA picker now hides Z-Image LoRAs with incompatible variants (e.g. ZBase
LoRAs when using Turbo model). LoRAs without a variant are always shown.
Backend loaders warn at runtime if a LoRA variant doesn't match the
transformer variant.

The FLUX.2 Klein transformer operates in BN-normalized latent space,
but init_latents from VAE encode were not being normalized before
being passed to the InpaintExtension. This caused a scale mismatch
when merging intermediate_latents (normalized) with noised_init_latents
(unnormalized), resulting in visible artifacts at mask blur boundaries.
Now normalize:
- init_latents_packed before passing to InpaintExtension
- noise_packed for correct interpolation in normalized space
- x (starting latents) for img2img/inpainting workflows

* add i18n for blend modes
* actually use translations for blend modes now
* move composite options into types.ts
* cleanup and comments
* update names
* move constant mapping out of function
* feat(ui): Refactor Blend Mode Implementation
- Blend Modes are not right click menu options anymore. Instead they rest above the layer panel as they do in other art programs readily available for each layer.
- Blend Modes have been resorted to match the listings of other art programs so users can avail their muscle memory.
- Blend Mode now defaults to `Normal` for each layer as it should.
- The extra layer operations have now been moved down to the `Operations Bar` at the bottom of the layer stack. This is to increase familiarity again with other art programs and also to make space for us in the top action bar.
- The Operations Bars operations have been resorted in order of usage that makes sense.
* fix: use source-over instead of normal
* fix: pixel fix for slightly offset action bar labels.
* feat(canvas): boolean raster merge creates new layer and disables sources
* (fix) lint errors
* remove extra typecast

* fix(flux2): Fix image quality degradation at resolutions > 1024x1024
This commit addresses severe quality degradation and artifacts when
generating images larger than 1024x1024 with FLUX.2 Klein models.
Root causes fixed:
1. Dynamic max_image_seq_len in scheduler (flux2_denoise.py)
- Previously hardcoded to 4096 (1024x1024 only)
- Now dynamically calculated based on actual resolution
- Allows proper schedule shifting at all resolutions
2. Smoothed mu calculation discontinuity (sampling_utils.py)
- Eliminated 40-50% mu value drop at seq_len 4300 threshold
- Implemented smooth cosine interpolation (4096-4500 transition zone)
- Gradual blend between low-res and high-res formulas
Impact:
- FLUX.2 Klein 9B: Major quality improvement at high resolutions
- FLUX.2 Klein 4B: Improved quality at high resolutions
- Baseline 1024x1024: Unchanged (no regression)
- All generation modes: T2I and Kontext (reference images)
Fixes: Community-reported quality degradation issue
See: Discord discussions in #garbage-bin and #devchat

* fix(flux2): Fix high-resolution quality degradation for FLUX.2 Klein
Fixes grid/diamond artifacts and color loss at resolutions > 1024x1024.
Root causes identified and fixed:
- BN normalization was incorrectly applied to random noise input
(diffusers only normalizes image latents from VAE.encode)
- BN denormalization must be applied to output before VAE decode
- mu parameter was resolution-dependent causing over-shifted schedules
at high resolutions (now fixed to 2.02, matching ComfyUI)
Changes:
- Remove BN normalization on noise input (not needed for N(0,1) noise)
- Preserve BN denormalization on denoised output (required for VAE)
- Fix mu to constant 2.02 for all resolutions (matches ComfyUI)
Tested at 2048x2048 with FLUX.2 Klein 4B

setting with hardcoded full denoising (start=0, end=1) in addOutpaint.
This caused denoising strength to be completely ignored whenever the
canvas bbox extended beyond the raster layer content, triggering outpaint
mode. The issue affected all model types (SDXL, SD1.5, FLUX, etc.).
Restore the original behavior by reading denoising_start/end from the
user's img2imgStrength setting via getDenoisingStartAndEnd().

* fix(flux2): support Heun scheduler for FLUX.2 Klein models
FlowMatchHeunDiscreteScheduler does not support dynamic shifting parameters
(use_dynamic_shifting, base_shift, max_shift, etc.) or sigmas/mu in set_timesteps.
This caused FLUX.2 Klein to fail when using Heun scheduler.
- Create Heun scheduler with only num_train_timesteps and shift parameters
- Use num_inference_steps instead of sigmas for Heun's set_timesteps call
- Euler and LCM schedulers continue to use full dynamic shifting support
* fix(flux2): fix Heun scheduler detection using inspect.signature
The previous hasattr check for state_in_first_order failed because
the attribute doesn't exist before set_timesteps() is called. Now
using inspect.signature to check for sigmas parameter support,
matching the FLUX1 implementation.

* Implemented ordering for expanded iterators
* Update test_graph_execution_state.py
Added a test for nested iterator execution ordering. (Failing at commit time!)
* Filter invalid nested-iterator parent mappings in _prepare()
When a graph has nested iterators, some "ready to run" node combinations do not actually belong together. Previously, the scheduler would still try to build nodes for those mismatched combinations, which could cause the same work to run more than once. This change skips any combination that is missing a valid iterator parent, so nested iterator expansions run once per intended item.
* Fixed Collect node ordering
* ruff
* Removed ordering guarantees from test_node_graph.py
* Fix iterator prep and type compatibility in graph execution
Include iterator nodes in nx_graph_flat so iterators are prepared/expanded correctly. Fix connection type checks to allow subclass-to-base via issubclass. Harden iterator/collector validation to fail cleanly instead of crashing on missing edges. Remove unused nx_graph_with_data(). Added tests to verify proper functionality.
* feat(model_manager): add missing models filter to Model Manager
Adds the ability to view and manage orphaned model database entries
where the underlying files have been deleted externally.
Changes:
- Add GET /v2/models/missing API endpoint to list models with missing files
- Add "Missing Files" filter option to Model Manager type filter dropdown
- Display "Missing Files" badge on models with missing files in the list
- Automatically exclude missing models from model selection dropdowns
to prevent users from selecting unavailable models for generation
* fix(ui): enable Select All checkbox for missing models filter
The Select All checkbox was disabled when the missing models filter was
active because the bulk actions component didn't use the missing models
query data. Now it correctly uses useGetMissingModelsQuery when the
filter is set to 'missing'.
* test(model_manager): add tests for missing model detection and bulk delete
Tests _scan_for_missing_models and the unregister/delete workflow for
models whose files have been removed externally.
* Chore Ruff check
When switching between FLUX.2 (model-less reference images) and other
models that require IP adapter/Redux models, the reference image configs
were not being converted, leaving stale config types that hid or showed
the wrong UI controls.

* fix(ui): improve DyPE field ordering and add 'On' preset option
- Add ui_order to DyPE fields (100, 101, 102) to group them at bottom of node
- Change DyPEPreset from Enum to Literal type for proper frontend dropdown support
- Add ui_choice_labels for human-readable dropdown options
- Add new 'On' preset to enable DyPE regardless of resolution
- Fix frontend input field sorting to respect ui_order (unordered first, then ordered)
- Bump flux_denoise node version to 4.4.0
* Chore Ruff check fix
* fix(flux): remove .value from dype_preset logging
DyPEPreset is now a Literal type (string) instead of an Enum,
so .value is no longer needed.
* fix(tests): update DyPE tests for Literal type change
Update test imports and assertions to use string constants
instead of Enum attributes since DyPEPreset is now a Literal type.
* feat(flux): add DyPE scale and exponent controls to Linear UI
- Add dype_scale (λs) and dype_exponent (λt) sliders to generation settings
- Add Zod schemas and parameter types for DyPE scale/exponent
- Pass custom values from Linear UI to flux_denoise node
- Fix bug where DyPE was enabled even when preset was "off"
- Add enhanced logging showing all DyPE parameters when enabled
* fix(flux): apply DyPE scale/exponent and add metadata recall
- Fix DyPE scale and exponent parameters not being applied in frequency
computation (compute_vision_yarn_freqs, compute_yarn_freqs now call
get_timestep_mscale)
- Add metadata handlers for dype_scale and dype_exponent to enable
recall from generated images
- Add i18n translations referencing existing parameter labels
* fix(flux): apply DyPE scale/exponent and add metadata recall
- Fix DyPE scale and exponent parameters not being applied in frequency
computation (compute_vision_yarn_freqs, compute_yarn_freqs now call
get_timestep_mscale)
- Add metadata handlers for dype_scale and dype_exponent to enable
recall from generated images
- Add i18n translations referencing existing parameter labels
* feat(ui): show DyPE scale/exponent only when preset is "on"
- Hide scale/exponent controls in UI when preset is not "on"
- Only parse/recall scale/exponent from metadata when preset is "on"
- Prevents confusion where custom values override preset behavior
* fix(dype): only allow custom scale/exponent with 'on' preset
Presets (auto, 4k) now use their predefined values and ignore
any custom_scale/custom_exponent parameters. Only the 'on' preset
allows manual override of these values.
This matches the frontend UI behavior where the scale/exponent
fields are only shown when 'On' is selected.
* refactor(dype): rename 'on' preset to 'manual'
Rename the 'on' DyPE preset to 'manual' to better reflect its purpose:
allowing users to manually configure scale and exponent values.
Updated in:
- Backend presets (DYPE_PRESET_ON -> DYPE_PRESET_MANUAL)
- Frontend UI labels and options
- Redux slice type definitions
- Zod schema validation
- Tests

Remove extra array wrapper when saving ref_images metadata for FLUX.2 Klein
and FLUX.1 Kontext reference images. The double-nested array [[...]] was
preventing recall from parsing the metadata correctly.
* chore(release): add flux.2-klein to whats new items & bump version
* doc(release): update the WhatsNew text
* chore(frontend): run lint:prettier and frontend-typegen
* fix(model_manager): detect Flux VAE by latent space dimensions instead of filename
VAE detection previously relied solely on filename pattern matching, which failed
for Flux VAE files with generic names like "ae.safetensors". Now probes the model's
decoder.conv_in weight shape to determine the latent space dimensions:
- 16 channels -> Flux VAE
- 4 channels -> SD/SDXL VAE (with filename fallback for SD1/SD2/SDXL distinction)
* fix(model_manager): add latent space probing for Flux2 VAE detection
Extend Flux2 VAE detection to also check for 32-dimensional latent space
(decoder.conv_in with 32 input channels) in addition to BatchNorm layers.
This provides more robust detection for Flux2 VAE files regardless of filename.

* docs: add DyPE implementation plan for FLUX high-resolution generation
Add detailed plan for porting ComfyUI-DyPE (Dynamic Position Extrapolation)
to InvokeAI, enabling 4K+ image generation with FLUX models without
training. Estimated effort: 5-7 developer days.
* docs: update DyPE plan with design decisions
- Integrate DyPE directly into FluxDenoise (no separate node)
- Add 4K preset and "auto" mode for automatic activation
- Confirm FLUX Schnell support (same base resolution as Dev)
* docs: add activation threshold for DyPE auto mode
FLUX can handle resolutions up to ~1.5x natively without artifacts.
Set activation_threshold=1536 so DyPE only kicks in above that.
* feat(flux): implement DyPE for high-resolution generation
Add Dynamic Position Extrapolation (DyPE) support to FLUX models,
enabling artifact-free generation at 4K+ resolutions.
New files:
- invokeai/backend/flux/dype/base.py: DyPEConfig and scaling calculations
- invokeai/backend/flux/dype/rope.py: DyPE-enhanced RoPE functions
- invokeai/backend/flux/dype/embed.py: DyPEEmbedND position embedder
- invokeai/backend/flux/dype/presets.py: Presets (off, auto, 4k)
- invokeai/backend/flux/extensions/dype_extension.py: Pipeline integration
Modified files:
- invokeai/backend/flux/denoise.py: Add dype_extension parameter
- invokeai/app/invocations/flux_denoise.py: Add UI parameters
UI parameters:
- dype_preset: off | auto | 4k
- dype_scale: Custom magnitude override (0-8)
- dype_exponent: Custom decay speed override (0-1000)
Auto mode activates DyPE for resolutions > 1536px.
Based on: https://github.com/wildminder/ComfyUI-DyPE
* feat(flux): add DyPE preset selector to Linear UI
Add Linear UI integration for FLUX DyPE (Dynamic Position Extrapolation):
- Add ParamFluxDypePreset component with Off/Auto/4K options
- Integrate preset selector in GenerationSettingsAccordion for FLUX models
- Add state management (paramsSlice, types) for fluxDypePreset
- Add dype_preset to FLUX denoise graph builder and metadata
- Add translations for DyPE preset label and popover
- Add zFluxDypePresetField schema definition
Fix DyPE frequency computation:
- Remove incorrect mscale multiplication on frequencies
- Use only NTK-aware theta scaling for position extrapolation
* feat(flux): add DyPE preset to metadata recall
- Add FluxDypePreset handler to ImageMetadataHandlers
- Parse dype_preset from metadata and dispatch setFluxDypePreset on recall
- Add translation key metadata.dypePreset
* chore: remove dype-implementation-plan.md
Remove internal planning document from the branch.
* chore(flux): bump flux_denoise version to 4.3.0
Version bump for dype_preset field addition.
* chore: ruff check fix
* chore: ruff format
* Fix truncated DyPE label in advanced options UI
Shorten the label from "DyPE (High-Res)" to "DyPE" to prevent text truncation in the sidebar. The high-resolution context is preserved in the informational popover tooltip.
* Add DyPE preset to recall parameters in image viewer
The dype_preset metadata was being saved but not displayed in the Recall Parameters tab. Add FluxDypePreset handler to ImageMetadataActions so users can see and recall this parameter.

* WIP: feat(flux2): add FLUX 2 Kontext model support
- Add new invocation nodes for FLUX 2:
- flux2_denoise: Denoising invocation for FLUX 2
- flux2_klein_model_loader: Model loader for Klein architecture
- flux2_klein_text_encoder: Text encoder for Qwen3-based encoding
- flux2_vae_decode: VAE decoder for FLUX 2
- Add backend support:
- New flux2 module with denoise and sampling utilities
- Extended model manager configs for FLUX 2 models
- Updated model loaders for Klein architecture
- Update frontend:
- Extended graph builder for FLUX 2 support
- Added FLUX 2 model types and configurations
- Updated readiness checks and UI components
* fix(flux2): correct VAE decode with proper BN denormalization
FLUX.2 VAE uses Batch Normalization in the patchified latent space
(128 channels). The decode must:
1. Patchify latents from (B, 32, H, W) to (B, 128, H/2, W/2)
2. Apply BN denormalization using running_mean/running_var
3. Unpatchify back to (B, 32, H, W) for VAE decode
Also fixed image normalization from [-1, 1] to [0, 255].
This fixes washed-out colors in generated FLUX.2 Klein images.
* feat(flux2): add FLUX.2 Klein model support with ComfyUI checkpoint compatibility
- Add FLUX.2 transformer loader with BFL-to-diffusers weight conversion
- Fix AdaLayerNorm scale-shift swap for final_layer.adaLN_modulation weights
- Add VAE batch normalization handling for FLUX.2 latent normalization
- Add Qwen3 text encoder loader with ComfyUI FP8 quantization support
- Add frontend components for FLUX.2 Klein model selection
- Update configs and schema for FLUX.2 model types
* Chore Ruff
* Fix Flux1 vae probing
* Fix Windows Paths schema.ts
* Add 4B und 9B klein to Starter Models.
* feat(flux2): add non-commercial license indicator for FLUX.2 Klein 9B
- Add isFlux2Klein9BMainModelConfig and isNonCommercialMainModelConfig functions
- Update MainModelPicker and InitialStateMainModelPicker to show license icon
- Update license tooltip text to include FLUX.2 Klein 9B
* feat(flux2): add Klein/Qwen3 variant support and encoder filtering
Backend:
- Add klein_4b/klein_9b variants for FLUX.2 Klein models
- Add qwen3_4b/qwen3_8b variants for Qwen3 encoder models
- Validate encoder variant matches Klein model (4B↔4B, 9B↔8B)
- Auto-detect Qwen3 variant from hidden_size during probing
Frontend:
- Show variant field for all model types in ModelView
- Filter Qwen3 encoder dropdown to only show compatible variants
- Update variant type definitions (zFlux2VariantType, zQwen3VariantType)
- Remove unused exports (isFluxDevMainModelConfig, isFlux2Klein9BMainModelConfig)
* Chore Ruff
* feat(flux2): add Klein 9B Base (undistilled) variant support
Distinguish between FLUX.2 Klein 9B (distilled) and Klein 9B Base (undistilled)
models by checking guidance_embeds in diffusers config or guidance_in keys in
safetensors. Klein 9B Base requires more steps but offers higher quality.
* feat(flux2): improve diffusers compatibility and distilled model support
Backend changes:
- Update text encoder layers from [9,18,27] to (10,20,30) matching diffusers
- Use apply_chat_template with system message instead of manual formatting
- Change position IDs from ones to zeros to match diffusers implementation
- Add get_schedule_flux2() with empirical mu computation for proper schedule shifting
- Add txt_embed_scale parameter for Qwen3 embedding magnitude control
- Add shift_schedule toggle for base (28+ steps) vs distilled (4 steps) models
- Zero out guidance_embedder weights for Klein models without guidance_embeds
UI changes:
- Clear Klein VAE and Qwen3 encoder when switching away from flux2 base
- Clear Qwen3 encoder when switching between different Klein model variants
- Add toast notification informing user to select compatible encoder
* feat(flux2): fix distilled model scheduling with proper dynamic shifting
- Configure scheduler with FLUX.2 Klein parameters from scheduler_config.json
(use_dynamic_shifting=True, shift=3.0, time_shift_type="exponential")
- Pass mu parameter to scheduler.set_timesteps() for resolution-aware shifting
- Remove manual shift_schedule parameter (scheduler handles this automatically)
- Simplify get_schedule_flux2() to return linear sigmas only
- Remove txt_embed_scale parameter (no longer needed)
This matches the diffusers Flux2KleinPipeline behavior where the
FlowMatchEulerDiscreteScheduler applies dynamic timestep shifting
based on image resolution via the mu parameter.
Fixes 4-step distilled Klein 9B model quality issues.
* fix(ui): fix FLUX.1 graph building with posCondCollect node lookup
The posCondCollect node was created with getPrefixedId() which generates
a random suffix (e.g., 'pos_cond_collect:abc123'), but g.getNode() was
called with the plain string 'pos_cond_collect', causing a node lookup
failure.
Fix by declaring posCondCollect as a module-scoped variable and
referencing it directly instead of using g.getNode().
* Remove Flux2 Klein Base from Starter Models
* Remove Logging
* Add Default Values for Flux2 Klein and add variant as additional info to from_base
* Add migrations for the z-image qwen3 encoder without a variant value
* Add img2img, inpainting and outpainting support for FLUX.2 Klein
- Add flux2_vae_encode invocation for encoding images to FLUX.2 latents
- Integrate inpaint_extension into FLUX.2 denoise loop for proper mask handling
- Apply BN normalization to init_latents and noise for consistency in inpainting
- Use manual Euler stepping for img2img/inpaint to preserve exact timestep schedule
- Add flux2_img2img, flux2_inpaint, flux2_outpaint generation modes
- Expand starter models with FP8 variants, standalone transformers, and separate VAE/encoders
- Fix outpainting to always use full denoising (0-1) since strength doesn't apply
- Improve error messages in model loader with clear guidance for standalone models
* Add GGUF quantized model support and Diffusers VAE loader for FLUX.2 Klein
- Add Main_GGUF_Flux2_Config for GGUF-quantized FLUX.2 transformer models
- Add VAE_Diffusers_Flux2_Config for FLUX.2 VAE in diffusers format
- Add Flux2GGUFCheckpointModel loader with BFL-to-diffusers conversion
- Add Flux2VAEDiffusersLoader for AutoencoderKLFlux2
- Add FLUX.2 Klein 4B/9B hardware requirements to documentation
- Update starter model descriptions to clarify dependencies install together
- Update frontend schema for new model configs
* Fix FLUX.2 model detection and add FP8 weight dequantization support
- Improve FLUX.2 variant detection for GGUF/checkpoint models (BFL format keys)
- Fix guidance_embeds logic: distilled=False, undistilled=True
- Add FP8 weight dequantization for ComfyUI-style quantized models
- Prevent FLUX.2 models from being misidentified as FLUX.1
- Preserve user-editable fields (name, description, etc.) on model reidentify
- Improve Qwen3Encoder detection by variant in starter models
- Add defensive checks for tensor operations
* Chore ruff format
* Chore Typegen
* Fix FLUX.2 Klein 9B model loading by detecting hidden_size from weights
Previously num_attention_heads was hardcoded to 24, which is correct for
Klein 4B but causes size mismatches when loading Klein 9B checkpoints.
Now dynamically calculates num_attention_heads from the hidden_size
dimension of context_embedder weights:
- Klein 4B: hidden_size=3072 → num_attention_heads=24
- Klein 9B: hidden_size=4096 → num_attention_heads=32
Fixes both Checkpoint and GGUF loaders for FLUX.2 models.
* Only clear Qwen3 encoder when FLUX.2 Klein variant changes
Previously the encoder was cleared whenever switching between any Klein
models, even if they had the same variant. Now compares the variant of
the old and new model and only clears the encoder when switching between
different variants (e.g., klein_4b to klein_9b).
This allows users to switch between different Klein 9B models without
having to re-select the Qwen3 encoder each time.
* Add metadata recall support for FLUX.2 Klein parameters
The scheduler, VAE model, and Qwen3 encoder model were not being
recalled correctly for FLUX.2 Klein images. This adds dedicated
metadata handlers for the Klein-specific parameters.
* Fix FLUX.2 Klein denoising scaling and Z-Image VAE compatibility
- Apply exponential denoising scaling (exponent 0.2) to FLUX.2 Klein,
matching FLUX.1 behavior for more intuitive inpainting strength
- Add isFlux1VAEModelConfig type guard to filter FLUX 1.0 VAEs only
- Restrict Z-Image VAE selection to FLUX 1.0 VAEs, excluding FLUX.2
Klein 32-channel VAEs which are incompatible
* chore pnpm fix
* Add FLUX.2 Klein to starter bundles and documentation
- Add FLUX.2 Klein hardware requirements to quick start guide
- Create flux2_klein_bundle with GGUF Q4 model, VAE, and Qwen3 encoder
- Add "What's New" entry announcing FLUX.2 Klein support
* Add FLUX.2 Klein built-in reference image editing support
FLUX.2 Klein has native multi-reference image editing without requiring
a separate model (unlike FLUX.1 which needs a Kontext model).
Backend changes:
- Add Flux2RefImageExtension for encoding reference images with FLUX.2 VAE
- Apply BN normalization to reference image latents for correct scaling
- Use T-coordinate offset scale=10 like diffusers (T=10, 20, 30...)
- Concatenate reference latents with generated image during denoising
- Extract only generated portion in step callback for correct preview
Frontend changes:
- Add flux2_reference_image config type without model field
- Hide model selector for FLUX.2 reference images (built-in support)
- Add type guards to handle configs without model property
- Update validators to skip model validation for FLUX.2
- Add 'flux2' to SUPPORTS_REF_IMAGES_BASE_MODELS
* Chore windows path fix
* Add reference image resizing for FLUX.2 Klein
Resize large reference images to match BFL FLUX.2 sampling.py limits:
- Single reference: max 2024² pixels (~4.1M)
- Multiple references: max 1024² pixels (~1M)
Uses same scaling approach as BFL's cap_pixels() function.
* Add user survey section to README
Added a section for new and returning users to take a survey.
* docs: add user survey link to WhatsNew
* Fix formatting issues in WhatsNew.tsx

* fix(model_manager): prevent Z-Image LoRAs from being misclassified as main models
Z-Image LoRAs containing keys like `diffusion_model.context_refiner.*` were being
incorrectly classified as main checkpoint models instead of LoRAs. This happened
because the `_has_z_image_keys()` function checked for Z-Image specific keys
(like `context_refiner`) without verifying if the file was actually a LoRA.
Since main models have higher priority than LoRAs in the classification sort order,
the incorrect main model classification would win.
The fix adds detection of LoRA-specific weight suffixes (`.lora_down.weight`,
`.lora_up.weight`, `.lora_A.weight`, `.lora_B.weight`, `.dora_scale`) and returns
False if any are found, ensuring LoRAs are correctly classified.
* refactor(mm): simplify _has_z_image_keys with early return
Return True directly when a Z-Image key is found instead of using an
intermediate variable.
* feat(z-image): add Seed Variance Enhancer node and Linear UI integration
Add a new conditioning node for Z-Image models that injects seed-based
noise into text embeddings to increase visual variation between seeds.
Backend:
- New invocation: z_image_seed_variance_enhancer.py
- Parameters: strength (0-2), randomize_percent (1-100%), seed
Frontend:
- State management in paramsSlice with selectors and reducers
- UI components in SeedVariance/ folder with toggle and sliders
- Integration in GenerationSettingsAccordion (Advanced Options)
- Graph builder integration in buildZImageGraph.ts
- Metadata recall handlers for remix functionality
- Translations and tooltip descriptions
Based on: github.com/Pfannkuchensack/invokeai-z-image-seed-variance-enhancer
* chore: ruff and typegen fix
* chore: ruff and typegen fix
* Revise seedVarianceStrength explanation
Updated description for seedVarianceStrength.
* Update description for seedVarianceStrength
* fix(z-image): correct noise range comment from [-1, 1] to [-1, 1)
torch.rand() generates [0, 1), so the scaled range excludes 1.

* feat(z-image): add `add_noise` option to Z-Image Denoise
Add the same `add_noise` option that exists in FLUX Denoise to Z-Image Denoise.
When set to false, no noise is added to the input latents during image-to-image,
allowing for more controlled transformations.
## Summary
Add a new "Denoise - Z-Image + Metadata" node
(`ZImageDenoiseMetaInvocation`) that extends the Z-Image denoise node
with metadata output for image recall functionality.
This follows the same pattern as existing `denoise_latents_meta`
(SD1.5/SDXL) and `flux_denoise_meta` (FLUX) nodes.
**Captured metadata:**
- `width` / `height`
- `steps`
- `guidance` (guidance_scale)
- `denoising_start` / `denoising_end`
- `scheduler`
- `model` (transformer)
- `seed`
- `loras` (if applied)
## Related Issues / Discussions
Enables metadata recall for Z-Image generated images, similar to
existing support for SD1.5, SDXL, and FLUX models.
## QA Instructions
1. Create a workflow using the new "Denoise - Z-Image + Metadata" node
2. Connect the metadata output to a "Save Image" node
3. Generate an image
4. Check that metadata is saved with the image (visible in image info
panel)
5. Verify all generation parameters are captured correctly

## Summary
Adds `model_cache_keep_alive_min` config option (minutes, default 5) to
automatically clear model cache after inactivity. Addresses memory
contention when running InvokeAI alongside other GPU applications like
Ollama.
**Implementation:**
- **Config**: New `model_cache_keep_alive_min` field in
`InvokeAIAppConfig` with 5-minute default
- **ModelCache**: Activity tracking on get/lock/unlock/put operations,
threading.Timer for scheduled clearing
- **Thread safety**: Double-check pattern handles race conditions,
daemon threads for clean shutdown
- **Integration**: ModelManagerService passes config to cache, calls
shutdown() on stop
- **Logging**: Smart timeout logging that only shows messages when
unlocked models are actually cleared
- **Tests**: Comprehensive unit tests with properly configured mock
logger
**Usage:**
```yaml
# invokeai.yaml
model_cache_keep_alive_min: 10 # Clear after 10 minutes idle
model_cache_keep_alive_min: 0 # Set to 0 for indefinite caching (old behavior)
```
**Key Behavior:**
- **Default timeout**: 5 minutes - models are automatically cleared
after 5 minutes of inactivity
- Clearing uses same logic as "Clear Model Cache" button (make_room with
1000GB)
- Only clears **unlocked** models (respects models actively in use
during generation)
- Timeout message only appears when models are actually cleared
- Debug logging available for timeout events when no action is taken
- Prevents misleading log entries during active generation
- Users can set to 0 to restore indefinite caching behavior
## Related Issues / Discussions
Addresses enhancement request for automatic model unloading from memory
after inactivity period.
## QA Instructions
1. **Test default behavior (5-minute timeout)**:
- Start InvokeAI without explicit config
- Run a generation
- Wait 6 minutes with no activity
- Check logs for "Clearing X unlocked model(s) from cache" message
- Verify cache is empty
2. **Test custom timeout**:
- Set `model_cache_keep_alive_min: 0.1` (6 seconds) in config
- Load a model (run generation)
- Wait 7+ seconds with no activity
- Check logs for "Clearing X unlocked model(s) from cache" message
- Verify cache is empty
3. **Test no timeout (old behavior)**:
- Set `model_cache_keep_alive_min: 0` in config
- Run generations and wait extended periods
- Verify models remain cached indefinitely
4. **Test during active use**:
- Run continuous generations with any timeout setting
- Verify no timeout messages appear during active use (models are
locked)
- After generation completes, wait for timeout and verify unlocked
models are cleared
## Merge Plan
N/A - Additive change with sensible defaults. The 5-minute default
enables automatic memory management while remaining practical for
typical workflows.

> I am reopening this issue. I'm running ollama and invoke on the same
server and I find their memory requirements are frequently clashing. It
would be helpful to offer users the option to have the model cache
automatically cleared after a fixed amount of inactivity. I would
suggest the following:
>
> 1. Introduce a new config file option `model_cache_keep_alive` which
specifies, in minutes, how long to keep a model in cache between
generations. The default is 0, which means to keep the model in cache
indefinitely, as is currently the case.
> 2. If no model generations occur within the timeout period, the model
cache is cleared using the same backend code as the "Clear Model Cache"
button in the queue tab.

— coding agent works faster and does higher quality work when set up for
your repo.
Instead of disabling mutually exclusive model selectors, automatically
clear conflicting models when a new selection is made. This applies to
VAE, Qwen3 Encoder, and Qwen3 Source selectors - selecting one now
clears the others. Also applies same logic during metadata recall.
Move Scheduler handler after MainModel in ImageMetadataHandlers so that
base-dependent recall logic (z-image scheduler) works correctly. The
Scheduler handler checks `base === 'z-image'` before dispatching the
z-image scheduler action, but this check failed when Scheduler ran
before MainModel was recalled.
* feat(flux): add scheduler selection for Flux models
Add support for alternative diffusers Flow Matching schedulers:
- Euler (default, 1st order)
- Heun (2nd order, better quality, 2x slower)
- LCM (optimized for few steps)
Backend:
- Add schedulers.py with scheduler type definitions and class mapping
- Modify denoise.py to accept optional scheduler parameter
- Add scheduler InputField to flux_denoise invocation (v4.2.0)
Frontend:
- Add fluxScheduler to Redux state and paramsSlice
- Create ParamFluxScheduler component for Linear UI
- Add scheduler to buildFLUXGraph for generation
* fix(flux): prevent progress percentage overflow with LCM scheduler
LCM scheduler may have more internal timesteps than user-facing steps,
causing user_step to exceed total_steps. This resulted in progress
percentage > 1.0, which caused a pydantic validation error.
Fix: Only call step_callback when user_step <= total_steps.
* Ruff format
* fix(flux): remove initial step-0 callback for consistent step count
Remove the initial step_callback at step=0 to match SD/SDXL behavior.
Previously Flux showed N+1 steps (step 0 + N denoising steps), while
SD/SDXL showed only N steps. Now all models display N steps consistently.
* feat(flux): add scheduler support with metadata recall
- Handle LCM scheduler by using num_inference_steps instead of custom sigmas
- Fix progress bar to show user-facing steps instead of internal scheduler steps
- Pass scheduler parameter to Flux denoise node in graph builder
- Add model-aware metadata recall for Flux scheduler

percentage > 1.0, which caused a pydantic validation error.
Fix: Only call step_callback when user_step <= total_steps.
* Ruff format
* fix(schedulers): remove initial step-0 callback for consistent step count
Remove the initial step_callback at step=0 to match SD/SDXL behavior.
Previously Flux/Z-Image showed N+1 steps (step 0 + N denoising steps),
while SD/SDXL showed only N steps. Now all models display N steps
consistently in the server log.
* feat(z-image): add scheduler support with metadata recall
- Handle LCM scheduler by using num_inference_steps instead of custom sigmas

When using GGUF-quantized models on MPS (Apple Silicon), the
dequantized tensors could end up on a different device than the
other operands in math operations, causing "Expected all tensors
to be on the same device" errors.
This fix ensures that after dequantization, tensors are moved to
the same device as the other tensors in the operation.

Add local_files_only fallback for Qwen3 tokenizer loading in both
Checkpoint and GGUF loaders. This ensures Z-Image models can generate
images offline after the initial tokenizer download.
The tokenizer is now loaded with local_files_only=True first, falling
back to network download only if files aren't cached yet.

* Fix an issue with multiple quick-queued generations after moving bbox
After moving the canvas bbox we still handed out the previous regional-guidance mask because only two parts of the system knew anything had changed. The adapter’s
cache key doesn’t include the bbox, so the next few graph builds reused the stale mask from before the move; if the user queued several runs back‑to‑back, every
background enqueue except the last skipped rerasterizing altogether because another raster job was still in flight. The fix makes the canvas manager invalidate each
region adapter’s cached mask whenever the bbox (or a related setting) changes, and—if a reraster is already running—queues up and waits instead of bailing. Now the
first run after a bbox edit forces a new mask, and rapid-fire enqueues just wait their turn, so every queued generation gets the correct regional prompt.

* fix(ui): make Z-Image model selects mutually exclusive
VAE and Qwen3 Encoder selects are disabled when Qwen3 Source is selected,
and vice versa. This prevents invalid model combinations.
* feat(ui): auto-select Z-Image component models on model change
When switching to a Z-Image model, automatically set valid defaults
if no configuration exists:
- Prefers Qwen3 Source (Diffusers model) if available
- Falls back to Qwen3 Encoder + FLUX VAE combination
This ensures the generate button is enabled immediately after selecting
a Z-Image model, without requiring manual configuration.
* fix(ui): save and restore Qwen3 Source model in metadata
Qwen3 Source (Diffusers Z-Image) model was not being saved to image
metadata or restored during Remix. This adds:
- Saving qwen3_source to metadata in buildZImageGraph
- ZImageQwen3SourceModel metadata handler for parsing and recall
- i18n translation for qwen3Source
Changes image self-attention from restricted (region-isolated) to unrestricted
(all image tokens can attend to each other), similar to the FLUX approach.
This fixes the issue where ZImage-Turbo with multiple regional guidance layers
would generate two separate/disconnected images instead of compositing them
into a single unified image.
The regional text-image attention remains restricted so that each region still
responds to its corresponding prompt.
Fixes#8715
LCM scheduler may have more internal timesteps than user-facing steps,
causing user_step to exceed total_steps. This resulted in progress
percentage > 1.0, which caused a pydantic validation error.
Fix: Only call step_callback when user_step <= total_steps.
Changed the default value of model_cache_keep_alive from 0 (indefinite)
to 5 minutes as requested. This means models will now be automatically
cleared from cache after 5 minutes of inactivity by default, unless
users explicitly configure a different value.
Users can still set it to 0 in their config to get the old behavior
of keeping models indefinitely.

## Summary
Fix Z-Image LoRA/DoRA model detection failing during installation.
Z-Image LoRAs use different key patterns than SD/SDXL LoRAs. The base
`LoRA_LyCORIS_Config_Base` class only checked for key suffixes like
`lora_A.weight` and `lora_B.weight`, but Z-Image LoRAs (especially those
in DoRA format) use:
- `lora_down.weight` / `lora_up.weight` (standard LoRA format)
- `dora_scale` (DoRA weight decomposition)
This PR overrides `_validate_looks_like_lora` in
`LoRA_LyCORIS_ZImage_Config` to recognize Z-Image specific patterns:
- Keys starting with `diffusion_model.layers.` (Z-Image S3-DiT
architecture)
- Keys ending with `lora_down.weight`, `lora_up.weight`,
`lora_A.weight`, `lora_B.weight`, or `dora_scale`
## Related Issues / Discussions
Fixes installation of Z-Image LoRAs trained with DoRA (Weight-Decomposed
Low-Rank Adaptation).
## QA Instructions
1. Download a Z-Image LoRA in DoRA format (e.g., from CivitAI with keys
like `diffusion_model.layers.X.attention.to_k.lora_down.weight`)
2. Try to install the LoRA via Model Manager
3. Verify the model is recognized as a Z-Image LoRA and installs
successfully
4. Verify the LoRA can be applied when generating with Z-Image

Two fixes for Z-Image LoRA support:
1. Override _validate_looks_like_lora in LoRA_LyCORIS_ZImage_Config to
recognize Z-Image specific LoRA formats that use different key patterns
than SD/SDXL LoRAs. Z-Image LoRAs use lora_down.weight/lora_up.weight
and dora_scale suffixes instead of lora_A.weight/lora_B.weight.
2. Fix _group_by_layer in z_image_lora_conversion_utils.py to correctly
group LoRA keys by layer name. The previous logic used rsplit with
maxsplit=2 which incorrectly grouped keys like:
- "to_k.alpha" -> layer "diffusion_model.layers.17.attention"
- "lora_down.weight" -> layer "diffusion_model.layers.17.attention.to_k"
Now uses suffix matching to ensure all keys for a layer are grouped
together (alpha, dora_scale, lora_down.weight, lora_up.weight).
Override _validate_looks_like_lora in LoRA_LyCORIS_ZImage_Config to
recognize Z-Image specific LoRA formats that use different key patterns
than SD/SDXL LoRAs.
Z-Image LoRAs (including DoRA format) use keys like:
- diffusion_model.layers.X.attention.to_k.lora_down.weight
- diffusion_model.layers.X.attention.to_k.dora_scale
The base LyCORIS config only checked for lora_A.weight/lora_B.weight
suffixes, missing the lora_down.weight/lora_up.weight and dora_scale
patterns used by Z-Image LoRAs.
Add support for alternative diffusers Flow Matching schedulers for Z-Image:
- Euler (default) - 1st order, optimized for Z-Image-Turbo (8 steps)

- LCM - Optimized for few-step generation
Backend:
- Extend schedulers.py with Z-Image scheduler types and mapping
- Add scheduler InputField to z_image_denoise invocation (v1.3.0)
- Refactor denoising loop to support diffusers schedulers

Frontend changes:
- Update buildZImageGraph to support regional conditioning collectors
- Update addRegions to create z_image_text_encoder nodes for regions
- Update addZImageLoRAs to handle optional negCond when guidance_scale=0
- Add Z-Image validation (no IP adapters, no autoNegative)

Since Z-Image uses guidance_scale=1.0 as "no CFG" (matching FLUX convention),
negative conditioning should only be created when guidance_scale > 1.

* feat(ui): add model path update for external models
Add ability to update file paths for externally managed models (models with
absolute paths). Invoke-controlled models (with relative paths in the models
directory) are excluded from this feature to prevent breaking internal
model management.
- Add ModelUpdatePathButton component with modal dialog
- Only show button for external models (absolute path check)
- Add translations for path update UI elements
* Added support for Windows UNC paths in ModelView.tsx:38-41. The isExternalModel function now detects:
Unix absolute paths: /home/user/models/...
Windows drive paths: C:\Models\... or D:/Models/...
Windows UNC paths: \\ServerName\ShareName\... or //ServerName/ShareName/...
* fix(ui): validate path format in Update Path modal to prevent invalid paths
When updating an external model's path, the new path is now validated to ensure
it follows an absolute path format (Unix, Windows drive, or UNC). This prevents
users from accidentally entering invalid paths that would cause the Update Path
button to disappear, leaving them unable to correct the mistake.
* fix(ui): extract isExternalModel to separate file to fix circular dependency
Moves the isExternalModel utility function to its own file to break the
circular dependency between ModelView.tsx and ModelUpdatePathButton.tsx.

## Summary
Fix shape mismatch when loading GGUF-quantized Z-Image transformer
models.
GGUF Z-Image models store `x_pad_token` and `cap_pad_token` with shape
`[3840]`, but diffusers `ZImageTransformer2DModel` expects `[1, 3840]`
(with batch dimension). This caused a `RuntimeError` on Linux systems
when loading models like `z_image_turbo-Q4_K.gguf`.
The fix:
- Dequantizes GGMLTensors first (since they don't support `unsqueeze`)
- Reshapes the tensors to add the missing batch dimension

Add Z-Image Turbo and related models to the starter models list:
- Z-Image Turbo (full precision, ~13GB)
- Z-Image Turbo quantized (GGUF Q4_K, ~4GB)
- Z-Image Qwen3 Text Encoder (full precision, ~8GB)
- Z-Image Qwen3 Text Encoder quantized (GGUF Q6_K, ~3.3GB)
- Z-Image ControlNet Union (Canny, HED, Depth, Pose, MLSD, Inpainting)
The quantized Turbo model includes the quantized Qwen3 encoder as a
dependency for automatic installation.
Implement Z-Image ControlNet as an Extension pattern (similar to FLUX ControlNet)
instead of merging control weights into the base transformer. This provides:
- Lower memory usage (no weight duplication)
- Flexibility to enable/disable control per step
- Cleaner architecture with separate control adapter
Key implementation details:
- ZImageControlNetExtension: computes control hints per denoising step
- z_image_forward_with_control: custom forward pass with hint injection
- patchify_control_context: utility for control image patchification
- ZImageControlAdapter: standalone adapter with control_layers and noise_refiner
Architecture matches original VideoX-Fun implementation:
- Hints computed ONCE using INITIAL unified state (before main layers)
- Hints injected at every other main transformer layer (15 control blocks)
- Control signal added after each designated layer's forward pass
V2.0 ControlNet support (control_in_dim=33):
- Channels 0-15: control image latents
- Channels 16-31: reference image (zeros for pure control)
- Channel 32: inpaint mask (1.0 = don't inpaint, use control signal)
VRAM usage is high.
- Auto-detect control_in_dim from adapter weights (16 for V1, 33 for V2.0)
- Auto-detect n_refiner_layers from state dict
- Add zero-padding for V2.0's additional channels
- Use accelerate.init_empty_weights() for efficient model creation
- Add ControlNet_Checkpoint_ZImage_Config to frontend schema
feat: Add Z-Image ControlNet support with spatial conditioning
Add comprehensive ControlNet support for Z-Image models including:
Backend:
- New ControlNet_Checkpoint_ZImage_Config for Z-Image control adapter models
- Z-Image control key detection (_has_z_image_control_keys) to identify control layers
- ZImageControlAdapter loader for standalone control models
- ZImageControlTransformer2DModel combining base transformer with control layers
- Memory-efficient model loading by building combined state dict
Add comprehensive support for Z-Image-Turbo (S3-DiT) models including:
Backend:
- New BaseModelType.ZImage in taxonomy
- Z-Image model config classes (ZImageTransformerConfig,
Qwen3TextEncoderConfig)
- Model loader for Z-Image transformer and Qwen3 text encoder
- Z-Image conditioning data structures
- Step callback support for Z-Image with FLUX latent RGB factors
Invocations:
- z_image_model_loader: Load Z-Image transformer and Qwen3 encoder
- z_image_text_encoder: Encode prompts using Qwen3 with chat template
- z_image_denoise: Flow matching denoising with time-shifted sigmas
- z_image_image_to_latents: Encode images to 16-channel latents
- z_image_latents_to_image: Decode latents using FLUX VAE
Frontend:
- Z-Image graph builder for text-to-image generation
- Model picker and validation updates for z-image base type
- CFG scale now allows 0 (required for Z-Image-Turbo)
- Clip skip disabled for Z-Image (uses Qwen3, not CLIP)
- Optimal dimension settings for Z-Image (1024x1024)
Technical details:
- Uses Qwen3 text encoder (not CLIP/T5)
- 16 latent channels with FLUX-compatible VAE
- Flow matching scheduler with dynamic time shift
- 8 inference steps recommended for Turbo variant
- bfloat16 inference dtype

The previous mixed-precision optimization for FP32 mode only converted
some VAE decoder layers (post_quant_conv, conv_in, mid_block) to the
latents dtype while leaving others (up_blocks, conv_norm_out) in float32.
This caused "expected scalar type Half but found Float" errors after
recent diffusers updates.
Simplify FP32 mode to consistently use float32 for both VAE and latents,
removing the incomplete mixed-precision logic. This trades some VRAM
usage for stability and correctness.
Also removes now-unused attention processor imports.
The Z-Image denoise node outputs latents, not images, so these mixins
were unnecessary. Metadata and board handling is correctly done in the
L2I (latents-to-image) node. This aligns with how FLUX denoise works.
- Add CustomDiffusersRMSNorm for diffusers.models.normalization.RMSNorm
- Add CustomLayerNorm for torch.nn.LayerNorm
- Register both in AUTOCAST_MODULE_TYPE_MAPPING
Enables partial loading (enable_partial_loading: true) for Z-Image models
by wrapping their normalization layers with device autocast support
The FLUX Dev license warning in model pickers used isCheckpointMainModelConfig
incorrectly:
```
isCheckpointMainModelConfig(config) && config.variant === 'dev'
```
This caused a TypeScript error because CheckpointModelConfig type doesn't
include the 'variant' property (it's extracted as `{ type: 'main'; format:
'checkpoint' }` which doesn't narrow to include variant).
Changes:
- Add isFluxDevMainModelConfig type guard that properly checks
base='flux' AND variant='dev', returning MainModelConfig
- Update MainModelPicker and InitialStateMainModelPicker to use new guard
- Remove isCheckpointMainModelConfig as it had no other usages
The function was removed because:
1. It was only used for detecting FLUX Dev models (incorrect use case)
2. No other code needs a generic "is checkpoint format" check
3. The pattern in this codebase is specific type guards per model variant
(isFluxFillMainModelModelConfig, isRefinerMainModelModelConfig, etc.)
Add robust device capability detection for bfloat16, replacing hardcoded
dtype with runtime checks that fallback to float16/float32 on unsupported
hardware. This prevents runtime failures on GPUs and CPUs without bfloat16.
Key changes:
- Add TorchDevice.choose_bfloat16_safe_dtype() helper for safe dtype selection
- Fix LoRA device mismatch in layer_patcher.py (add device= to .to() call)
- Replace all assert statements with descriptive exceptions (TypeError/ValueError)
- Add hidden_states bounds check and apply_chat_template fallback in text encoder
- Add GGUF QKV tensor validation (divisible by 3 check)
- Fix CPU noise generation to use float32 for compatibility
- Remove verbose debug logging from LoRA conversion utils
Add support for saving and recalling Z-Image component models (VAE and
Qwen3 Encoder) in image metadata.
Backend:
- Add qwen3_encoder field to CoreMetadataInvocation (version 2.1.0)
Frontend:
- Add vae and qwen3_encoder to Z-Image graph metadata
- Add Qwen3EncoderModel metadata handler for recall
- Add ZImageVAEModel metadata handler (uses zImageVaeModelSelected
instead of vaeSelected to set Z-Image-specific VAE state)
- Add qwen3Encoder translation key
This enables "Recall Parameters" / "Remix Image" to restore the VAE
and Qwen3 Encoder settings used for Z-Image generations.
Add support for loading Z-Image transformer and Qwen3 encoder models
from single-file safetensors format (in addition to existing diffusers
directory format).
Changes:
- Add Main_Checkpoint_ZImage_Config and Main_GGUF_ZImage_Config for
single-file Z-Image transformer models
- Add Qwen3Encoder_Checkpoint_Config for single-file Qwen3 text encoder
- Add ZImageCheckpointModel and ZImageGGUFCheckpointModel loaders with
automatic key conversion from original to diffusers format
- Add Qwen3EncoderCheckpointLoader using Qwen3ForCausalLM with fast
loading via init_empty_weights and proper weight tying for lm_head
- Update z_image_denoise to accept Checkpoint format models
Add comprehensive support for GGUF quantized Z-Image models and improve component flexibility:
Backend:
- New Main_GGUF_ZImage_Config for GGUF quantized Z-Image transformers
- Z-Image key detection (_has_z_image_keys) to identify S3-DiT models
- GGUF quantization detection and sidecar LoRA patching for quantized models
- Qwen3Encoder_Qwen3Encoder_Config for standalone Qwen3 encoder models
Model Loader:
- Split Z-Image model
Move Flux layer structure check before metadata check to prevent misidentifying Z-Image LoRAs (which use `diffusion_model.layers.X`) as Flux AI Toolkit format. Flux models use `double_blocks` and `single_blocks` patterns which are now checked first regardless of metadata presence.
* feat: Add bulk delete functionality for models, LoRAs, and embeddings
Implements a comprehensive bulk deletion feature for the model manager that allows users to select and delete multiple models, LoRAs, and embeddings at once.
Key changes:
Frontend:
- Add multi-selection state management to modelManagerV2 slice
- Update ModelListItem to support Ctrl/Cmd+Click multi-selection with checkboxes
- Create ModelListHeader component showing selection count and bulk actions
- Create BulkDeleteModelsModal for confirming bulk deletions
- Integrate bulk delete UI into ModelList with proper error handling
- Add API mutation for bulk delete operations
Backend:
- Add POST /api/v2/models/i/bulk_delete endpoint
- Implement BulkDeleteModelsRequest and BulkDeleteModelsResponse schemas
- Handle partial failures with detailed error reporting
- Return lists of successfully deleted and failed models
This feature significantly improves user experience when managing large model libraries, especially when restructuring model storage locations.
Fixes issue where users had to delete models individually after moving model files to new storage locations.
* fix: prevent model list header from scrolling with content
* fix: improve error handling in bulk model deletion
- Added proper error serialization using serialize-error for better error logging
- Explicitly defined BulkDeleteModelsResponse type instead of relying on generated schema reference
* refactor: improve code organization in ModelList components
- Reordered imports to follow conventional grouping (external, internal, then third-party utilities)
- Added type assertion for error serialization to satisfy TypeScript
- Extracted inline event handler into named callback function for better readability
* refactor: consolidate Button component props to single line
* feat(ui): enhance model manager bulk selection with select-all and actions menu
- Added select-all checkbox in navigation header with indeterminate state support
- Replaced single delete button with actions dropdown menu for future extensibility
- Made checkboxes always visible instead of conditionally showing on selection
- Moved model filtering logic to ModelListNavigation for select-all functionality
- Improved UX by showing selection state for filtered models only

## Summary
This fixes a bug in which private directory paths on the host could be
leaked to the user interface. The error occurs during the `scan_folders`
operation when a subdirectory is not accessible. The UI shows a
permission denied error message, followed by the path of the offending
directory. This patch limits the error message to the error type only
and does not give further details.
## Related Issues / Discussions
This bug was reported in a private DM on the Discord server.
## QA Instructions
Before applying this PR, go to ***Model Manager -> Add Model -> Scan
Folder*** and enter the path of a directory that has subdirectories that
the backend should not have access to, for example `/etc`. Press the
***Scan Folder*** button. You will see a Permission Denied error message
that gives away the path of the first inaccesislbe subdirectory.
After applying this PR, you will see just the Permission Denied error
without details.

Add route and model record service method to reidentify a model. This
re-probes the model files and replaces the model's config with the new
one if it does not error.
We had an "infill methods" route that long ago told the frontend infill
method, upscale method (model), NSFW checker, and watermark feature
availability.
None of these were used except for the patchmatch check. Removed them,
made the check exclusively for patchmatch, updated related code in redux
app startup listeners and settings modal.

Previously, we had a multi-phase strategy to identify models from their
files on disk:
1. Run each model config classes' `matches()` method on the files. It
checks if the model could possibly be an identified as the candidate
model type. This was intended to be a quick check. Break on the first
match.
2. If we have a match, run the config class's `parse()` method. It
derive some additional model config attrs from the model files. This was
intended to encapsulate heavier operations that may require loading the
model into memory.
3. Derive the common model config attrs, like name, description,
calculate the hash, etc. Some of these are also heavier operations.
This strategy has some issues:
- It is not clear how the pieces fit together. There is some
back-and-forth between different methods and the config base class. It
is hard to trace the flow of logic until you fully wrap your head around
the system and therefore difficult to add a model architecture to the
probe.
- The assumption that we could do quick, lightweight checks before
heavier checks is incorrect. We often _must_ load the model state dict
in the `matches()` method. So there is no practical perf benefit to
splitting up the responsibility of `matches()` and `parse()`.
- Sometimes we need to do the same checks in `matches()` and `parse()`.
In these cases, splitting the logic is has a negative perf impact
because we are doing the same work twice.
- As we introduce the concept of an "unknown" model config (i.e. a model
that we cannot identify, but still record in the db; see #8582), we will
_always_ run _all_ the checks for every model. Therefore we need not try
to defer heavier checks or resource-intensive ops like hashing. We are
going to do them anyways.
- There are situations where a model may match multiple configs. One
known case are SD pipeline models with merged LoRAs. In the old probe
API, we relied on the implicit order of checks to know that if a model
matched for pipeline _and_ LoRA, we prefer the pipeline match. But, in
the new API, we do not have this implicit ordering of checks. To resolve
this in a resilient way, we need to get all matches up front, then use
tie-breaker logic to figure out which should win (or add "differential
diagnosis" logic to the matchers).
- Field overrides weren't handled well by this strategy. They were only
applied at the very end, if a model matched successfully. This means we
cannot tell the system "Hey, this model is type X with base Y. Trust me
bro.". We cannot override the match logic. As we move towards letting
users correct mis-identified models (see #8582), this is a requirement.
We can simplify the process significantly and better support "unknown"
models.
Firstly, model config classes now have a single `from_model_on_disk()`
method that attempts to construct an instance of the class from the
model files. This replaces the `matches()` and `parse()` methods.
If we fail to create the config instance, a special exception is raised
that indicates why we think the files cannot be identified as the given
model config class.
Next, the flow for model identification is a bit simpler:
- Derive all the common fields up-front (name, desc, hash, etc).
- Merge in overrides.
- Call `from_model_on_disk()` for every config class, passing in the
fields. Overrides are handled in this method.
- Record the results for each config class and choose the best one.
The identification logic is a bit more verbose, with the special
exceptions and handling of overrides, but it is very clear what is
happening.
The one downside I can think of for this strategy is we do need to check
every model type, instead of stopping at the first match. It's a bit
less efficient. In practice, however, this isn't a hot code path, and
the improved clarity is worth far more than perf optimizations that the
end user will likely never notice.

Fixes a test failure introduced by
https://github.com/pydantic/pydantic/pull/11957
TL;DR: "after" model validators should be instance methods, not class
methods. Batch model updated to use an instance method, which fixes the
failing test.
- Move migration of model-specific ui_types into BaseInvocation. This
gives us access to the node and field names, so the warnings are more
useful to the end user.
- Ensure we serialize the fields' json_schema_extra with enum values.
This wasn't a problem until now, when it interferes with migrating
ui_type cleanly. It's a transparent change.
- Improve warnings when validating fields (which includes the ui_type
migration logic)
Do not use whole layer as trigger for histo recalc; use the canvas cache
of the layer - it more reliably indicates when the layer pixel data has
changed, and fixes an issue where we can miss the first histo calc due
to race conditiong with async layer bbox calculation.

Fixed an issue where bounding boxes could grow exponentially when created at small sizes. The problem occurred because Konva Transformer modifies scaleX/scaleY rather than width/height directly, and the scale values weren't consistently reset after being applied to dimensions.
Changes:
- Ensure scale values are always reset to 1 after applying to dimensions
- Add minimum size constraints to prevent zero/negative dimensions
- Fix scale handling in transformend, dragend, and initial bbox creation

There was a really confusing aspect of the SAM pipeline classes where
they accepted deeply nested lists of different dimensions (bbox, points,
and labels).
The lengths of the lists are related; each point must have a
corresponding label, and if bboxes are provided with points, they must
be same length.
I've refactored the backend API to take a single list of SAMInput
objects. This class has a bbox and/or a list of points, making it much
simpler to provide the right shape of inputs.
Internally, the pipeline classes take rejigger these input classes to
have the correct nesting.
The Nodes still have an awkward API where you can provide both bboxes
and points of different lengths, so I added a pydantic validator that
enforces correct lenghts.
Certain items in redux are ephemeral and omitted from persisted slices.
On rehydration, we need to inject these values back into the slice.
But there was an issue taht could prevent slice migrations from running
during rehydration.
The migrations look for the `_version` key in state and migrate the
slice accordingly.
The logic that merged in the ephemeral values accidentally _also_ merged
in the `_version` key if it didn't already exist. This happened _before_
migrations are run.
This causes problems for slices that didn't have a `_version` key and
then have one added via migration.
For example, the params slice didn't have a `_version` key until the
previous commit, which added `_version` and changed some other parts of
state in a migration.
On first load of the updated code, we have a catch-22 kinda situation:
- The persisted params slice is the old version. It needs to have both
`_version` and some other data added to it.
- We deserialize the state and then merge in ephemeral values. This
inadvertnetly also merged in the `_version` key.
- We run the slice migration. It sees there is a `_version` key and
thinks it doesn't need to run. The extra data isn't added to the slice.
The slice is parsed against its zod schema and fails because the new
data is missing.
- Because the parse failed, we treat the user's persisted data as
invalid and overwrite it with initial state, potentially causing data
loss.
The fix is to be more selective when merging in the ephemeral state
before migration - this is now done by checking which keys are on the
persist denylist and only adding those key.
This tells react that the component is a new instance each time we
change the image. Which, in turn, prevents a flash of the
previously-selected image during image switching and
progress-image-to-output-image-ing.
This has been an issue for a long time. I suspect it wasn't noticed
until now because it's finicky to trigger - you have to click and
release very quickly, without moving the mouse at all.
Must set cross origin whenever we load an image from a URL to prevent
race conditions where browser caches an image with no CORS, then canvas
attempts to load it with CORS, resulting in browser rejecting the
request before it is made
If incompatible LoRAs are added, prevent Invoking.
The logic to prevent adding incompatible LoRAs to graphs already
existed. This does not fix any generation bugs; just a visual
inconsistency where it looks like Invoke would use an incompatible LoRA.
Gemini 2.5 Flash makes no guarantees about output image sizes. Our
existing logic always rendered staged images on Canvas at the bbox dims
- not the image's physical dimensions. When Gemini returns an image that
doesn't match the bbox, it would get squished.
To rectify this, the canvas staging area renderer is updated to render
its images using their physical dimensions, as opposed to their
configured dimensions (i.e. bbox).
A flag on CanvasObjectImage enables this rendering behaviour.
Then, when saving the image as a layer from staging area, we use the
physical dimensions.
When the bbox and physical dimensions do not match, the bbox is not
touched, so it won't exactly encompass the staged image. No point in
resizing the bbox if the dimensions don't match - the next image could
be a different size, and the sizes might not be valid (it's an external
resource, after all).
- Disable LoRAs instead of deleting them when base model changes
- Update toast message to indicate that we may have _updated_ a model
(prev just sayed cleared or disabled)
- Do not change ref image models if the new base model doesn't support
them. For example, changing from SDXL to Imagen does not update the ref
image model or alert the user, because Imagen does not support ref
images. Switching from Imagen to FLUX does update the ref image model
and alert the user. Just a bit less noisy.

Fixes errors like `AttributeError: module 'cv2.ximgproc' has no
attribute 'thinning'` which occur because there is a conflict between
our own `opencv-contrib-python` dependency and the `invisible-watermark`
library's `opencv-python`.
Determine the "base" step for floats. If no `multipleOf` is provided,
the "base" step is `undefined`, meaning the float can have any number of
decimal places.
The UI library does its own step constrains though and is rounding to 3
decimal places. Probably need to update the logic in the UI library to
have truly arbitrary precision for float fields.
I ran into a race condition where I set a HF token and it was valid, but
somehow this error toast still appeared. The conditional feel through to
an assertion that we never expected to get to, which crashed the UI.
Handled the unexpected case gracefully now.
- Move the estimation logic to utility functions
- Estimate memory _within_ the encode and decode methods, ensuring we
_always_ estimate working memory when running a VAE
Three changes needed to make scrollIntoView and "Locate in Gallery" work
reliably.
1. Use setTimeout to work around race condition with scrollIntoView in
gallery.
It was possible to call scrollIntoView before react-virtuoso was ready.
I think react-virtuoso was initialized but hadn't rendered/measured its
items yet, so when we scroll to e.g. index 742, the items have a zero
height, so it doesn't actually scroll down. Then the items render.
Setting a timeout here defers the scroll until after the next event loop
cycle, by which time we expect react-virutoso to be ready.
2. Ensure the scollIntoView effect in gallery triggers any time the
selection is touched by making its dependency the array of selected
images, not just the last selected image name.
The "locate in gallery" functionality works by selecting an image.
There's a reactive effect in the gallery that runs when the last
selected image changes and scrolls it into view.
But if you already have an image selected, selecting it again will not
change the image name bc it is a string primitive. The useEffect ignores
the selection.
So, if you clicked "locate in gallery" on an image that was already
selected, it wouldn't be scrolled into view - even if you had already
scrolled away from it.
To work around this, the effect now uses the whole selection array as
its dependency. Whenever the selection changes, we get a new array,
which triggers the effect.
3. Gallery slice had some checks to avoid creating a new array of
selected image names in state when the selected images didn't change.
For example, if image "abc" was selected, and we selected "abc" again,
instead of creating a new array with the same "abc" image, we bailed
early. IIRC this optimization addressed a rerender issue long ago.
This optimization needs to be removed in order for fix#2 above to work.
We now _want_ a new array whenever selection is set - even if it didn't
actually change.
This feature added a lot of unexpected complexity in graph building /
metadata recall and is unintuitive user experience. 99% of the time, the
style prompt should be exactly the main prompt.
You can still use style prompts in workflows, but in an effort to reduce
complexity in the linear UI, we are removing this rarely-used feature.
When installing a model, the previous, graceful logic would increment a
suffix on the destination path until found a free path for the model.
But because model file installation and record creation are not in a
transaction, we could end up moving the file successfully and fail to
create the record:
- User attempts to install an already-installed model
- Attempt to move the downloaded model from download tempdir to
destination path
- The path already exists
- Add `_1` or similar to the path until we find a path that is free
- Move the model
- Create the model record
- FK constraint violation bc we already have a model w/ that name, but
the model file has already been moved into the invokeai dir.
Closes#8416
Prevents a large spike in VRAM when preparing to denoise w/ multiple ref
images.
There doesn't appear to be any different in image quality / ref
adherence when concatenating in latent space vs image space, though
images _are_ different.
If the transformer fills up VRAM, then when we VAE encode kontext
latents, we'll need to first offload the transformer (partially, if
partial loading is enabled).
No need to do this - we can encode kontext latents before loading the
transformer to reduce model thrashing.
Tell the model manager that we need some extra working memory for VAE
encoding operations to prevent OOMs.
See previous commit for investigation and determination of the magic
numbers used.
This safety measure is especially relevant now that we have FLUX Kontext
and may be encoding rather large ref images. Without the working memory
estimation we can OOM as we prepare for denoising.
See #8405 for an example of this issue on a very low VRAM system. It's
possible we can have the same issue on any GPU, though - just a matter
of hitting the right combination of models loaded.
This commit includes a task delegated to Claude to investigate our VAE
working memory calculations and investigation results.
See VAE_INVESTIGATION.md for motivation and detail. Everything else is
its output.
Result data includes empirical measurements for all supported model
architectures at a variety of resolutions and fp16/fp32 precision.
Testing conducted on a 4090.
The summarized conclusion is that our working memory estimations for
decoding are spot-on, but decoding also needs some extra working memory.
Empirical measurements suggest ~45% the amount needed for encoding.
A followup commit will implement working memory estimations for VAE
encoding with the goal of preventing unexpected OOMs during encode.

- Do not reset dimensions when resetting generation settings (they are
model-dependent, and we don't change model-dependent settings w/ that
butotn)
- Do not reset bbox when resetting canvas layers
- Show reset canvas layers button only on canvas tab
- Show reset generation settings button only on canvas or generate tab
Disable these items while staging:
- New Canvas From Image context menu
- Edit image hook & launchpad button
- Generate from Text launchpad button (only while on canvas tab)
- Use a Layout Image launchpad button
When unsafe_disable_picklescan is enabled, instead of erroring on
detections or scan failures, a warning is logged.
A warning is also logged on app startup when this setting is enabled.
The setting is disabled by default and there is no change in behaviour
when disabled.
Implements intelligent spatial tiling that arranges multiple reference
images in a virtual canvas, choosing between horizontal and vertical
placement to maintain a square-like aspect ratio
This fixes an issue where gallery's auto-scroll-into-view for selected
images didn't work, and users instead saw a "Unable to find image..."
debug log message in JS console.
1. Fix the run script to properly read the GPU_DRIVER
2. Cloned and adjusted the ROCM dockerbuild for docker
3. Adjust the docker-compose.yml to use the cloned dockerbuild
It's not clear why we were copying downloaded models to the destination
dir instead of moving them. I cannot find a reason for it, and I am able
to install single-file and diffusers models just fine with the change.
This fixes an issue where model installation requires 2x the model's
size (bc we were copying the model over).
Previously, we used pathlib's `with_suffix()` method to change add a
suffix (e.g. ".safetensors") to a model when installing it.
The intention is to add a suffix to the model's name - but that method
actually replaces everything after the first period.
This can cause different models to be installed under the same name!
For example, the FLUX models all end up with the same name:
- "FLUX.1 schnell.safetensors" -> "FLUX.safetensors"
- "FLUX.1 dev.safetensors" -> "FLUX.safetensors"
The fix is easy - append the suffix using string formatting instead of
using pathlib.
This issue has existed for a long time, but was exacerbated in
075345bffd in which I updated the names of
our starter models, adding ".1" to the FLUX model names. Whoops!
## Summary
Move client state persistence from browser to server.
- Add new client state persistence service to handle reading and writing
client state to db & associated router. The API mirrors that of
LocalStorage/IndexedDB where the set/get methods both operate on _keys_.
For example, when we persist the canvas state, we send only the new
canvas state to the backend - not the whole app state.
- The data is very flexibly-typed as a pydantic `JsonValue`. The client
is expected to handle all data parsing/validation (it must do this
anyways, and does this today).
- Change persistence from debounced to throttled at 2 seconds. Maybe
less is OK? Trying to not hammer the server.
- Add new persistence storage driver in client and use it in
redux-remember. It does its best to avoid extraneous persist requests,
caching the last data it persisted and noop-ing if there are no changes.
- Storage driver tracks pending persist actions using ref counts (bc
each slice is persisted independently). If there user navigates away
from the page during a persist request, it will give them the "you may
lose something if you navigate away" alert.
- This "lose something" alert message is not customizable (browser
security reasons).
- The alert is triggered only when the user closes the tape while a
persist network request is mid-flight. It's possible that the user makes
a change and closes the page before we start persisting. In this case,
they will lose the last 2 seconds of data.
- I tried making triggering the alert when a persist was waiting to
start, and it felt off.
- Maybe the alert isn't even necessary. Again you'd lose 2s of data at
most, probably a non issue. IMO after trying it, a subtle indicator
somewhere on the page is probably less confusing/intrusive.
- Fix an issue where the `redux-remember` enhancer was added _last_ in
the enhancer chain, which prevented us detecting when a persist has
succeeded. This required a small change to the `unserialze` utility
(used during rehydration) to ensure slices enhanced with `redux-undo`
are set up correctly as they are rehydrated.
- Restructure the redux store code to avoid circular dependencies. I
couldn't figure out how to do this without just smooshing it all into
the main `store.ts` file. Oh well.
Implications:
- Because client state is now on the server, different browsers will
have the same studio state. For example, if I start working on something
in Firefox, if I switch to Chrome, I have the same client state.
- Incognito windows won't do anything bc client state is server-side.
- It takes a bit longer for persistence to happen thanks to the
debounce, but there's now an indicator that tells you your stuff isn't
saved yet.
- Resetting the browser won't fix an issue with your studio state. You
must use `Reset Web UI` to fix it (or otherwise hit the appropriate
endpoint). It may be possible to end up in a Catch-22 where you can't
click the button and get stuck w/ a borked studio - I think to think
through this a bit more, might not be an issue.
- It probably takes a bit longer to start up, since we need to retrieve
client state over network instead of directly with browser APIs.
Other notes:
- We could explore adding an "incognito" mode, enabled via
`invokeai.yaml` setting or maybe in the UI. This would temporarily
disable persistence. Actually, I don't think this really makes sense, bc
all the images would be saved to disk.
- The studio state is stored in a single row in the DB. Currently, a
static row ID is used to force the studio state to be a singleton. It is
_possible_ to support multiple saved states. Might be a solve for app
workspaces.

Try it out. It's pretty straightforward. Error states are the main
things to test - for example, network blips. The new server-side
persistence driver is the only real functional change - everything else
is just kinda shuffling things around to support it.

Fix nodes ui: Make nodes dot background to be the same as the snap to grid size and position
Update to Flow.tsx
Changes the size and offset of the dots background to be the same size as the snap to grid, and also fix the background dot pattern alignment.
Currently, the snapGrid is 25x25, and the default background dot gap is 20x20, these do not align. This is fixed by making the gap property of the background the same as the snapGrid.
Additionally, there is a bug in the rectFlow background code that incorrectly sets the offset to be the centre of the dot pattern with the default offset of 0. To work around this issue, setting the background offset property to the snapGrid size will realign the dot pattern correctly.
I have logged a bug for the rectFlow background issue in its repo.
https://github.com/xyflow/xyflow/issues/5405
Update workflowSettingsSlice.ts
Change the default settings for auto layout nodeSpacing and layerSpacing to 30 instead of 32. This will make the x position of auto layed nodes land on the snap to grid positions.
Because the node width (320) + 30 = 350 which is divisible by the snap to grid size of 25.
We intermittently get an error like this:
```
TypeError: Cannot read properties of undefined (reading 'length')
```
This error is caused by a `redux-undo`-enhanced slice being rehydrated
without the extra stuff it adds to the slice to make it undoable (e.g.
an array of `past` states, the `present` state, array of `future`
states, and some other metadata).
`redux-undo` may need to check the length of the past/future arrays as
part of its internal functionality. These keys don't exist so we get the
error. I'm not sure _why_ they don't exist - my understanding of
`redux-undo` is that it should be checking and wrapping the state w/ the
history stuff automatically. Seems to be related to `redux-remember` -
may be a race condition.
The solution is to ensure we wrap rehydrated state for undoable slices
as we rehydrate them. I discovered the solution while troubleshooting
#8314 when the changes therein somehow triggered the issue to start
occuring every time instead of rarely.
* Add auto layout controls using elkjs to node editor
Introduces auto layout functionality for the node editor using elkjs, including a new UI popover for layout options (placement strategy, layering, spacing, direction). Adds related state and actions to workflowSettingsSlice, updates translations, and ensures elkjs is included in optimized dependencies.
* feat(nodes): Improve workflow auto-layout controls and accuracy
- The auto-layout settings panel is updated to use `Select` dropdowns and `NumberInput`
- The layout algorithm now uses the actual rendered dimensions of nodes from the DOM, falling back to estimates only when necessary. This results in a much more accurate and predictable layout.
- The ELKjs library integration is refactored to fix some warnings
* Update useAutoLayout.ts
prettier

* build(ui): import elkjs directly
* updated to use dagrejs for autolayout
updated to use dagrejs - it has less layout options but is already included
but this is still WIP as some nodes don't report the height correctly. I am still investigating this...
* Update useAutoLayout.ts
update to fix layout issues
* minor updates
- pretty useAutoLayout.ts
- add missing type import in ViewportControls.tsx
- update pnpm-lock.yaml with elkjs removed
* Update ViewportControls.tsx
pnpm fix
* Fix Frontend check + single node selection fix
Fix Frontend check - remove unused export from workflowSettingsSlice.ts
Update so that if you have a single node selected, it will auto layout all nodes, as this is a common thing to have a single node selected and means that you don't have to unselect it.
* feat(ui): misc improvements for autolayout
- Split popover into own component
- Add util functions to get node w/h
- Use magic wand icon for button
- Fix sizing of input components
- Use CompositeNumberInput instead of base chakra number input
- Add zod schemas for string values and use them in the component to
ensure state integrity
* chore(ui): lint

There was a subtle issue where the progress image wasn't ever cleared,
preventing the context menu from working on staging area preview images.
The staging area preview images were displaying the last progress image
_on top of_ the result image. Because the image elements were so small,
you wouldn't notice that you were looking at a low-res progress image.
Right clicking a progress image gets you no menu.
If you refresh the page or switch tabs, this would fix itself, because
those actions clear out the progress images. The result image would then
be the topmost element, and the context menu works.
Fixing this without introducing a flash of empty space as the progress
image was hidden required a bit of refactoring. We have to wait for the
result image element to load before clearing out the progress.
Result - progress images appear to "resolve" to result images in the
staging area without any blips or jank, and the context menu works after
that happens.
Was running into difficultlies reasoning about the logic and couldn't
write tests because it was all in react.
Moved logic outside react, updated context, make it testable.
Simplify the canvas auto-switch logic to not rely on the preview images
loading. This fixes an issue where offscreen preview images didn't get
auto-switched to. Images are now loaded directly.
Fix an issue in certain browsers/builds causing a runtime error.
A zod enum has a .options property, which is an array of all the options
for the enum. This is handy for when you need to derive something from a
zod schema.
In this case, we represented the possible focus regions in the zod enum,
then derived a mapping of region names to set of target HTML elements.
Why isn't important, but suffice to say, we were using the .options
property for this.
But actually, we were using .options.values(), then calling .reduce() on
that. An array's .values() method returns an _array iterator_. Array
iterators do not have .reduce() methods!
Except, apparently in some environments they do - it depends on the JS
engine and whether or not polyfills for iterator helpers were included
in the build.
Turns out my dev environment - and most user browsers - do provide
.reduce(), so we didn't catch this error. It took a large deployment and
error monitoring to catch it.
I've refactored the code to totally avoid deriving data from zod in this
way.
- Add a context manager to the SqliteDatabase class which abstracts away
creating a transaction, committing it on success and rolling back on
error.
- Use it everywhere. The context manager should be exited before
returning results. No business logic changes should be present.
- Apparently locales must use hyphens instead of underscores. This must
have been a fairly recent change that we didn't catch. It caused i18n to
throw for Brasilian Portuguese and both Simplified and Traditional
Mandarin. Change the locales to use the right strings.
- Move the theme + locale provider inside of the error boundary. This
allows errors with locals to be caught by the error boundary instead of
hard-crashing the app. The error screen is unstyled if this happens but
at least it has the reset button.
- Add a migration for the system slice to fix existing users' language
selections. For example, if the user had an incorrect language setting
of `zh_CN`, it will be changed to the correct `zh-CN`.
The range-based fetching logic had a subtle bug - it didn't keep track
of what the _current_ visible range is - only the ranges that the user
last scrolled to.
When an image was added to the gallery, the logic saw that the images
had changed, but thought it had already loaded everything it needed to,
so it didn't load the new image.
The updated logic tracks the current visible range separately from the
accumulated scroll ranges to address this issue.
When the user scrolls in the gallery, we are alerted of the new range of
visible images. Then we fetch those specific images.
Previously, each change of range triggered a throttled function to fetch
that range. The throttle timeout was 100ms.
Now, each change of range appends that range to a list of ranges and
triggers the throttled fetch. The timeout is increased to 500ms, but to
compensate, each fetch handles all ranges that had been accumulated
since the last fetch.
The result is far fewer network requests, but each of them gets more
images.
- Smaller staged image previews.
- Move autoswitch buttons to staging area toolbar, remove from settings
popover and the little three-dots menu. Use persisted autoswitch
setting, which is renamed from `defaultAutoSwitch` to
`stagingAreaAutoSwitch`.
- Fix issue with misaligned border radii in staging area preview images.
Required small changes to DndImage and its usage elsewhere.
- Fix issue where staging area toolbar could show up without any
previews in the list.
- Migrate canvas settings slice to use zod schema and inferred types for
its state.

Reverted incomplete change to how queue items are listed. In the future
I think we should redo it to work like the gallery. For now, it is back
the way it was in v5.
When percentage is zero, the progress bar looks the same as it does when
no generation is in progress. Render it as indeterminate (pulsing) when

Ensure disabled tabs are never mounted:
- Add didLoad flag to configSlice, default false
- Always merge in config - even it is is empty
- On first merge, set didLoad to true
- Until didLoad is true, mark _all_ tabs as disabled
This gets around an issue where tabs are all enabled for a brief moment
before the config is loaded.
A bit hacky but it works.

Revert unnecessary validation changes in multi-diffusion
Fix in python instead of graphbuilder
tidy(ui): remove extraneous comment
The previous logic had a subtle python bug related the scope and nested
generators.
Python generators are lazily evaluated - the expressions are stored and
only evaluated when needed (e.g. calling next() or list() on them)
The old logic used a variable `s`, which was continually overwritten as
the generator expressions were created. As a result, the final mappings
all use the _final_ value for `s`.
Following the consequences of this down the line, we find that collect
nodes can end up with multiple edges from exactly one of their ancestor
nodes, instead of one edge from each ancestor. Notably, it's only the
source _node_id_ that is affected - the source _fields_ have the correct
values.
So the invalid edges will point to a real node and a real field, but the
field exists on a different node.
---
This can result in a number of cryptic problems - include an error about
incompatible field types:
```
InvalidEdgeError: Field types are incompatible
(31758fd5-14a8-4de7-a840-b73ec1a1b94f.value ->
3459c793-41a2-4d82-9204-7df2d6d099ba.item)
```
Here are the conditions that lead to this error:
- The collect node has at least two incoming connections.
- The two incoming connections come from nodes of different types.
- The nodes both output a value of the same type, but the name of the
output field differs between them.
---
This commit uses non-generator logic to build up the mappings, avoiding
the issue entirely. As a bonus, it is much easier to read.
Previously we used python's own type introspection utilties to determine
input and output field types. We can use pydantic to get the field types
in a clearer, more direct way.
This improvement also exposed an awkward behaviour in this utility,
where it would return None when a field doesn't exist. I've added a
comment in the code describing the issue, but changing it would require
some significant changes and I don't want to risk breaking anything.

When we delete images, boards, or do any other board mutation, we need
to invalidate numerous query caches and related internal frontend state.
This gets complicated very quickly.
We can drastically reduce the complexity by having the backend return
some more information when we make these mutations.
For example, when deleting a list of images by name, we can return a
list of deleted image name and affected boards. The frontend can use
this information to determine which queries to invalidate with far less
tedium.
This will also enable the more efficient storage of images (e.g. in the
gallery selection). Previously, we had to store the entire image DTO
object, else we wouldn't be able to figure out which queries to
invalidate. But now that the backend tells us exactly what images/boards
have changed, we can just store image names in frontend state. This
amounts to a substantial improvement in DX and reduction in frontend
complexity.
When the invocation cache is used, we might skip all progress images. This can prevent auto-switch-on-first-progress from working, as we don't get any of those events.
It's much easier to only support auto-switch on complete.
This appears to be a bug in Chakra UI v2 - use of a fallback component makes the ref passed to an image end up undefined. Had to remove the skeleton loader fallback component.

In #7724 we made a number of perf optimisations related to enqueuing. One of these optimisations included moving the enqueue logic - including expensive prep work and db writes - to a separate thread.
At the same time manual DB locking was abandoned in favor of WAL mode.
Finally, we set `check_same_thread=False` to allow multiple threads to access the connection at a given time.
I think this may be the cause of #7950:
- We start an enqueue in a thread (running in bg)
- We dequeue
- Dequeue pulls a partially-written queue item from DB and we get the errors in the linked issue
To be honest, I don't understand enough about SQLite to confidently say that this kind of race condition is actually possible. But:
- The error started popping up around the time we made this change.
- I have reviewed the logic from enqueue to dequeue very carefully _many_ times over the past month or so, and I am confident that the error is only possible if we are getting unexpectedly `NULL` values from the DB.
- The DB schema includes `NOT NULL` constraints for the column that is apparently returning `NULL`.
- Therefore, without some kind of race condition or schema issue, the error should not be possible.
- The `enqueue_batch` call is the only place I can find where we have the possibility of a race condition due to async logic. Everywhere else, all DB interaction for the queue is synchronous, as far as I can tell.
This change retains the perf benefits by running the heavy enqueue prep logic in a separate thread, but moves back to the main thread for the DB write. It also uses an explicit transaction for the write.
Will just have to wait and see if this fixes the issue.
This reduces peak memory usage at a negligible cost. Queue items typically take on the order of seconds, making the time cost of a GC essentially free.
Not a great idea on a hotter code path though.
We've long suspected there is a memory leak in Invoke, but that may not be true. What looks like a memory leak may in fact be the expected behaviour for our allocation patterns.
We observe ~20 to ~30 MB increase in memory usage per session executed. I did some prolonged tests, where I measured the process's RSS in bytes while doing 200 SDXL generations. I found that it eventually leveled off at around 100 generations, at which point memory usage had climbed by ~900MB from its starting point.
I used tracemalloc to diff the allocations of single session executions and found that we are allocating ~20MB or so per session in `ModelPatcher.apply_ti()`.
In `ModelPatcher.apply_ti()` we add tokens to the tokenizer when handling TIs. The added tokens should be scoped to only the current invocation, but there is no simple way to remove the tokens afterwards.
As a workaround for this, we clone the tokenizer, add the TI tokens to the clone, and use the clone to when running compel. Afterwards, this cloned tokenizer is discarded.
The tokenizer uses ~20MB of memory, and it has referrers/referents to other compel stuff. This is what is causing the observed increases in memory per session!
We'd expect these objects to be GC'd but python doesn't do it immediately. After creating the cond tensors, we quickly move on to denoising. So there isn't any time for the GC to happen to free up its existing memory arenas/blocks to reuse them. Instead, python needs to request more memory from the OS.
We can improve the situation by immediately calling `del` on the tokenizer clone and related objects. In fact, we already had some code in the compel nodes to `del` some of these objects, but not all.
Adding the `del`s vastly improves things. We hit peak RSS in half the sessions (~50 or less) and it's now ~100MB more than starting value. There is still a gradual increase in memory usage until we level off.
* build: prevent `opencv-python` from being installed
Fixes this error: `AttributeError: module 'cv2.ximgproc' has no attribute 'thinning'`
`opencv-contrib-python` supersedes `opencv-python`, providing the same API + additional features. The two packages should not be installed at the same time to avoid conflicts and/or errors.
The `invisible-watermark` package requires `opencv-python`, but we require the contrib variant.
This change updates `pyproject.toml` to prevent `opencv-python` from ever being installed using a `uv` features called dependency overrides.

When a layer is initialized, we do not yet know its bbox, so we cannot fit the stage view to the layer. We have to wait for the bbox calculation to finish. Previously, we had no way to wait unti lthat bbox calculation was complete to take an action.
For example, this means we could not fit the layers to the stage immediately after creating a new layer, bc we don't know the dimensions of the layer yet.
This callback lets us do that. When creating a new canvas from an image, we now...
- Register a bbox update callback to fit the layers to stage
- Layer is created
- Canvas initializes the layer's entity adapter module (layer's width and height are set to zero at this point)
- Canvas calculates the bbox
- Bbox is updated (width and height are now correct)
- Callback is ran, fitting layer to stage
Also change import order to ensure CLI args are handled correctly. Had to do this bc importing `InvocationRegistry` before parsing args resulted in the `--root` CLI arg being ignored.
Add `heuristic_resize_fast`, which does the same thing as `heuristic_resize`, except it's about 20x faster.
This is achieved by using opencv for the binary edge handling isntead of python, and checking only 100k pixels to determine what kind of image we are working with.
Besides being much faster, it results in cleaner lines for resized binary canny edge maps, and has results in fewer misidentified segmentation maps.
Tested against normal images, binary canny edge maps, grayscale HED edge maps, segmentation maps, and normal images.
Tested resizing up and down for each.
Besides the new utility function, I needed to swap the `opencv-python` dep for `opencv-contrib-python`, which includes `cv2.ximgproc.thinning`. This function accounts for a good chunk of the perf improvement.

When we do our field type overrides to allow invocations to be instantiated without all required fields, we were not modifying the annotation of the field but did set the default value of the field to `None`.
This results in an error when doing a ser/de round trip. Here's what we end up doing:
```py
from pydantic import BaseModel, Field
class MyModel(BaseModel):
foo: str = Field(default=None)
```
And here is a simple round-trip, which should not error but which does:
```py
MyModel(**MyModel().model_dump())
# ValidationError: 1 validation error for MyModel
# foo
# Input should be a valid string [type=string_type, input_value=None, input_type=NoneType]
# For further information visit https://errors.pydantic.dev/2.11/v/string_type
```
To fix this, we now check every incoming field and update its annotation to match its default value. In other words, when we override the default field value to `None`, we make its type annotation `<original type> | None`.
This prevents the error during deserialization.
This slightly alters the schema for all invocations and outputs - the values of all fields without default values are now typed as `<original type> | None`, reflecting the overrides.
This means the autogenerated types for fields have also changed for fields without defaults:
```ts
// Old
image?: components["schemas"]["ImageField"];
// New
image?: components["schemas"]["ImageField"] | null;
```
This does not break anything on the frontend.

If provided, `<NavigateToModelManagerButton />` will render, even if `disabledTabs` includes "models". If provided, `<NavigateToModelManagerButton />` will run the callback instead of switching tabs within the studio.
The button's tooltip is now just "Manage Models" and its icon is the same as the model manager tab's icon ([CUBE!](https://www.youtube.com/watch?v=4aGDCE6Nrz0)).
There is a subtle change in behaviour with the new model probe API.
Previously, checks for model types was done in a specific order. For example, we did all main model checks before LoRA checks.
With the new API, the order of checks has changed. Check ordering is as follows:
- New API checks are run first, then legacy API checks.
- New API checks categorized by their speed. When we run new API checks, we sort them from fastest to slowest, and run them in that order. This is a performance optimization.
Currently, LoRA and LLaVA models are the only model types with the new API. Checks for them are thus run first.
LoRA checks involve checking the state dict for presence of keys with specific prefixes. We expect these keys to only exist in LoRAs.
It turns out that main models may have some of these keys.
For example, this model has keys that match the LoRA prefix `lora_te_`: https://civitai.com/models/134442/helloyoung25d
Under the old probe, we'd do the main model checks first and correctly identify this as a main model. But with the new setup, we do the LoRA check first, and those pass. So we import this model as a LoRA.
Thankfully, the old probe still exists. For now, the new probe is fully disabled. It was only called in one spot.
I've also added the example affected model as a test case for the model probe. Right now, this causes the test to fail, and I've marked the test as xfail. CI will pass.
Once we enable the new API again, the xfail will pass, and CI will fail, and we'll be reminded to update the test.
In the previous commit, the LLaVA model was updated to support partial loading.
In this commit, the SigLIP model is updated in the same way.
This model is used for FLUX Redux. It's <4GB and only ever run in isolation, so it won't benefit from partial loading for the vast majority of users. Regardless, I think it is best if we make _all_ models work with partial loading.
PS: I also fixed the initial load dtype issue, described in the prev commit. It's probably a non-issue for this model, but we may as well fix it.
The model manager has two types of model cache entries:
- `CachedModelOnlyFullLoad`: The model may only ever be loaded and unloaded as a single object.
- `CachedModelWithPartialLoad`: The model may be partially loaded and unloaded.
Partial loaded is enabled by overwriting certain torch layer classes, adding the ability to autocast the layer to a device on-the-fly. See `CustomLinear` for an example.
So, to take advantage of partial loading and be cached as a `CachedModelWithPartialLoad`, the model must inherit from `torch.nn.Module`.
The LLaVA classes provided by `transformers` do inherit from `torch.nn.Module`, but we wrap those classes in a separate class called `LlavaOnevisionModel`. The wrapper encapsulate both the LLaVA model and its "processor" - a lightweight class that prepares model inputs like text and images.
While it is more elegant to encapsulate both model and processor classes in a single entity, this prevents the model cache from enabling partial loading for the chunky vLLM model.
Fixing this involved a few changes.
- Update the `LlavaOnevisionModelLoader` class to operate on the vLLM model directly, instead the `LlavaOnevisionModel` wrapper class.
- Instantiate the processor directly in the node. The processor is lightweight and does its business on the CPU. We don't need to worry about caching in the model manager.
- Remove caching support code from the `LlavaOnevisionModel` wrapper class. It's not needed, because we do not cache this class. The class now only handles running the models provided to it.
- Rename `LlavaOnevisionModel` to `LlavaOnevisionPipeline` to better represent its purpose.
These changes have a bonus effect of fixing an OOM crash when initially loading the models. This was most apparent when loading LLaVA 7B, which is pretty chunky.
The initial load is onto CPU RAM. In the old version of the loaders, we ignored the loader's target dtype for the initial load. Instead, we loaded the model at `transformers`'s "default" dtype of fp32.
LLaVA 7B is fp16 and weighs ~17GB. Loading as fp32 means we need double that amount (~34GB) of CPU RAM. Many users only have 32GB RAM, so this causes a _CPU_ OOM - which is a hard crash of the whole process.
With the updated loaders, the initial load logic now uses the target dtype for the initial load. LLaVA now needs the expected ~17GB RAM for its initial load.
PS: If we didn't make the accompanying partial loading changes, we still could have solved this OOM. We'd just need to pass the initial load dtype to the wrapper class and have it load on that dtype. But we may as well fix both issues.
PPS: There are other models whose model classes are wrappers around a torch module class, and thus cannot be partially loaded. However, these models are typically fairly small and/or are run only on their own, so they don't benefit as much from partial loading. It's the really big models (like LLaVA 7B) that benefit most from the partial loading.

I am at loss as the to cause of this bug. The styles that I needed to change to fix it haven't been changed in a couple months. But these do seem to fix it.
Closes#7910
This query can have potentially large responses. Keeping them around for 24 hours essentially a hardcoded memory leak. Use the default for RTKQ of 60 seconds.
When users generate on the canvas or upscaling tabs, we parse prompts through dynamic prompts before invoking. Whenever the prompt or other settings change, we run dynamic prompts.
Previously, we used a redux listener to react to changes to dynamic prompts' dependent state, keeping the processed dynamic prompts synced. For example, when the user changed the prompt field, we re-processed the dynamic prompts.
This requires that all redux actions that change the dependent state be added to the listener matcher. It's easy to forget actions, though, which can result in the dynamic prompts state being stale.
For example, when resetting canvas state, we dispatch an action that resets the whole params slice, but this wasn't in the matcher. As a result, when resetting canvas, the dynamic prompts aren't updated. If the user then clicks Invoke (with an empty prompt), the last dynamic prompts state will be used.
For example:
- Generate w/ prompt "frog", get frog
- Click new canvas session
- Generate without any prompt, still get frog
To resolve this, the logic that keeps the dynamic prompts synced is moved from the listener to a hook. The way the logic is triggered is improved - it's now triggered in a useEffect, which is run when the dependent state changes. This way, it doesn't matter _how_ the dependent state changes - the changes will always be "seen", and the dynamic prompts will update.
Add `useCanvasIsBusySafe()` hook. This is like `useCanvasIsBusy()`, but when the canvas is not initialized, it gracefully falls back to false instead of raising.
Because app tabs are lazy-loaded, the canvas is not initialized until the user visits that tab. If the page loads up on the workflows tab, the canvas will be uninitialized until the user clicks on it.
This graceful fallback behaviour allows actions like sending an image to canvas to work even when the canvas is not yet initialized. These actions are exposed in the image context menu, and previously were hidden when the canvas was not initialized. We can now show these actions and use them even when the canvas is uninitialized.
- Add `useCanvasIsBusySafe()` hook
- Use the new hook in the image context menu for send to canvas actions
- Do not use `<CanvasManagerProviderGate />` in the image context menu (this was hiding the actions when canvas was uninitialized)
When calling `ctx.drawImage()`, if the image to be drawn has a width of height of 0, the call will raise.
In this change, I have carefully reviewed the call hierarchy for all of our own code that calls this method and ensured that each call has error handling.
Well, with one exception - I'm not sure how to handle errors in `invokeai/frontend/web/src/common/hooks/useClientSideUpload.ts`. But this should never be an issue in that hook - it's a Canvas problem.

Whether a workflow is published or not shouldn't be something stored on the client. It's properly server-side state.
This change removes the `is_published` flag from redux and updates all references to the flag to use the getWorkflow query.
It also updates the socket event listener that handles session complete events. When a validation run completes, we invalidate the tags for the getWorkflow query. We need to do a bit of juggling to avoid a race condition (documented in the code). Works well though.
Previously, we maintained an `isTouched` flag in redux state to indicate if a workflow had unsaved changes. We manually updated this whenever we changed something on the workflow.
This was tedious and error-prone. It also didn't handle undo/redo, so if you made a change to a node and undid it, we'd still think the workflow had unsaved changes.
Moving forward, we use a simpler and more robust strategy by hashing the server's version of the workflow and comparing it to the client's version of the workflow.
The hashing uses `stable-hash`, which is both fast and, well, stable. Most importantly, the ordering of keys in hashed objects does not change the resultant hash.
- Remove `isTouched` state entirely.
- Extract the logic that builds the "preview" workflow object from redux state into its own hook. This "preview" workflow is what we send to the server when saving a workflow. This "preview" workflow is effectively the client version of the workflow.
- Add `useDoesWorkflowHaveUnsavedChanges()` hook, which compares the hash of the client workflow and server workflow (if it exists).
- Add `useIsWorkflowUntouched()` hook, which compares the hash of the client workflow and the initial workflow that you get when you click new workflow.
- Remove `reactflow` workaround in the nodes slice undo/redo filter. When we set the nodes state while loading a workflow, `reactflow` emits a nodes size/placement change event. This triggered up our `isTouched` flag logic and marked the workflow as unsaved right from the get-go. With the new strategy to track touched status, this workaround can be removed.
- Update all logic that tracked the old `isTouched` flag to use the new hooks.
Previously, the workflow form's root element id was random. Every time we reset the workflow editor, the root id changed. This makes it difficult to check if the workflow editor is untouched (in its default state).
Now that root element's id is simply "root". I can't imagine any way that this would break anything.
This allows it to pull in sentencepiece on its own. In 0.10.0, it didn't have this package listed as a dependency, but in recent releases it does. So we are able to remove sentencepiece as an explicit dep.
The fixes in this module monkeypatched `torch` to resolve some issues with FP16 on macOS. These issues have long since been resolved.
Included in the now-removed fixes is `CustomSlicedAttentionProcessor`, which is intended to reduce memory requirements for MPS. This overrides `diffusers`' own `SlicedAttentionProcessor`.
Unfortunately, `attention_type: sliced` produces hot garbage with the fixes and black images without the fixes. So this class appears to now be a moot point.
Regardless, SDPA is supported on MPS and very efficient, so sliced attention is largely obsolete.
In https://github.com/pydantic/pydantic/pull/10029, pydantic made an improvement to its generated JSON schemas (OpenAPI schemas). The previous and new generated schemas both meet the schema spec.
When we parse the OpenAPI schema to generate node templates, we use some typeguard to narrow schema components from generic OpenAPI schema objects to a node field schema objects. The narrower node field schema objects contain extra data.
For example, they contain a `field_kind` attribute that indicates it the field is an input field or output field. These extra attributes are not part of the OpenAPI spec (but the spec allows does allow for this extra data).
This typeguard relied on a pydantic implementation detail. This was changed in the linked pydantic PR, which released with v2.9.0. With the change, our typeguard rejects input field schema objects, causing parsing to fail with errors/warnings like `Unhandled input property` in the JS console.
In the UI, this causes many fields - mostly model fields - to not show up in the workflow editor.
The fix for this is very simple - instead of relying on an implementation detail for the typeguard, we can check if the incoming schema object has any of our invoke-specific extra attributes. Specifically, we now look for the presence of the `field_kind` attribute on the incoming schema object. If it is present, we know we are dealing with an invocation input field and can parse it appropriately.
In `ObjectSerializerDisk`, we use `torch.load` to load serialized objects from disk. With torch 2.6.0, torch defaults to `weights_only=True`. As a result, torch will raise when attempting to deserialize anything with an unrecognized class.
For example, our `ConditioningFieldData` class is untrusted. When we load conditioning from disk, we will get a runtime error.
Torch provides a method to add trusted classes to an allowlist. This change adds an arg to `ObjectSerializerDisk` to add a list of safe globals to the allowlist and uses it for both `ObjectSerializerDisk` instances.
Note: My first attempt inferred the class from the generic type arg that `ObjectSerializerDisk` accepts, and added that to the allowlist. Unfortunately, this doesn't work.
For example, `ConditioningFieldData` has a `conditionings` attribute that may be one some other untrusted classes representing model-specific conditioning data. So, even if we allowlist `ConditioningFieldData`, loading will fail when torch deserializes the `conditionings` attribute.
This is a squash of a lot of scattered commits that became very difficult to clean up and make individually. Sorry.
Besides the new UI, there are a number of notable changes:
- Publishing logic is disabled in OSS by default. To enable it, provided a `disabledFeatures` prop _without_ "publishWorkflow".
- Enqueuing a workflow is no longer handled in a redux listener. It was hard to track the state of the enqueue logic in the listener. It is now in a hook. I did not migrate the canvas and upscaling tabs - their enqueue logic is still in the listener.
- When queueing a validation run, the new `useEnqueueWorkflows()` hook will update the payload with the required data for the run.
- Some logic is added to the socket event listeners to handle workflow publish runs completing.
- The workflow library side nav has a new "published" view. It is hidden when the "publishWorkflow" feature is disabled.
- I've added `Safe` and `OrThrow` versions of some workflows hooks. These hooks typically retrieve some data from redux. For example, a node. The `Safe` hooks return the node or null if it cannot be found, while the `OrThrow` hooks return the node or raise if it cannot be found. The `OrThrow` hooks should be used within one of the gate components. These components use the `Safe` hooks and render a fallback if e.g. the node isn't found. This change is required for some of the publish flow UI.
- Add support for locking the workflow editor. When locked, you can pan and zoom but that's it. Currently, it is only locked during publish flow and if a published workflow is opened.
This message is logged _every_ time we retrieve a list of models if there is an invalid model. Previously it logged the _whole_ row which can be a lot of data. Truncate the row to 64 characters to reduce log pollution.

Previously, reactflow appears to have handled an edge case when using its `applyChanges` utility. If a change was provided without an item, it would skip that change. For example, an "add edge" change that somehow passed `null` as the edge, instead of a valid edge.
In our workflow loading and validation logic, invalid edges were removed from the array using `delete edges[i]`. This left "holes" in the array of edges. We then asked `reactflow` to add these edges to state. When it encountered one of the "holes", it skipped over it.
In a recent release (unsure which, somewhere between the latest v11 and ~v12.4) this seems to have changed. It no longer skips over the "holes" and instead trusts the data. This can cause a couple issues:
- Error when loading the workflow if `reactflow` attempt to do anything with the nonexistent edge.
- If somehow the workflow makes it into state with "holes" in the array of edges, all sorts of other stuff breaks when our code does anything with the nonexistent edge.
Two-part fix:
- Update the invalid edge handling to not use `delete edges[i]`. Instead, as we check each edge, we add invalid ones to a set. Then, after all the checks are finished, filter out the invalid edges. The resultant edges array has no holes.
- Simplify the logic around setting nodes and edges in redux. Previously we were using `reactflow`'s `applyChanges` utils, but this does literally nothing except take extra CPU cycles. We can simply set the loaded nodes and edges directly in redux. Perhaps we were using `applyChanges` because it addressed the "holes" issue? Not sure. But we don't need it now.

## Summary
`timm` below 1.0.0 prevents llava models from working (broken in
transformers). but `controlnet-aux` pins `timm` to an earlier version
because otherwise it was breaking the ZoeDepth controlnet.
we don't use ZoeDepth (replaced by depthAnything), and downgrading
controlnet-aux seems to be acceptable.
more context here:
https://github.com/huggingface/controlnet_aux/issues/106https://github.com/huggingface/controlnet_aux/pull/101
Note that this results in some warnings on startup, stemming from
controlnet-aux:
we can probably silence the warnings as a separate enhancement

Before FLUX Fill was merged, we didn't do any checks for the model variant. We always returned "normal".
To determine if a model is a FLUX Fill model, we need to check the state dict for a specific key. Initially, this logic was too strict and rejected quantized FLUX models. This issue was resolved, but it turns out there is another failure mode - some fine-tunes use a different key.
This change further reduces the strictness, handling the alternate key and also falling back to "normal" if we don't see either key. This effectively restores the previous probing behaviour for all FLUX models.
Closes#7856Closes#7859
The polynomial fit isn't perfect and we end up with alpha values of 1 instead of 0 when applying the mask. This in turn causes issues on canvas where outputs aren't 100% transparent and individual layer bbox calculations are incorrect.

## Summary
This PR moves type definitions out of `config.py` into a new
`taxonomy.py` module.
The goal is to reduce clutter in `config.py`, and to resolve circular
import issues by isolating these types in a dedicated module with
(almost) no internal dependencies.
Because so many places import these definitions, these changes touch 73
files.
Additional changes:
- Removed star imports using "removestar" tool
- Added the commit to `.git-blame-ignore-revs` to avoid noise in git
blame history

In #7780 we added FLUX Fill support, and needed the probe to be able to distinguish between "normal" FLUX models and FLUX Fill models.
Logic was added to the probe to check a particular state dict key (input channels), which should be 384 for FLUX Fill and 64 for other FLUX models.
The new logic was stricter and instead of falling back on the "normal" variant, it raised when an unexpected value for input channels was detected.
This caused failures to probe for BNB-NF4 quantized FLUX Dev/Schnell, which apparently only have 1 input channel.
After checking a variety of FLUX models, I loosened the strictness of the variant probing logic to only special-case the new FLUX Fill model, and otherwise fall back to returning the "normal" variant. This better matches the old behaviour and fixes the import errors.
Closes#7822

Previously we used erode/dilate and a Gaussian blur to expand and fade the edges of Canvas masks. The implementation a number of problems:
- Erode/dilate kernel sizes were not calculated correctly, and extra iterations were run to compensate. The result is the blur size, which should have been pixels, was very inaccurate and unreliable.
- What we want is to add a "soft bleed" - like a drop shadow with no offset - starting from the edge of the mask, extending out by however many pixels. But Gaussian blur does not do this. The blurred area starts _inside_ the mask and extends outside it. So it kinda blurs inwards and outwards. We compensated for this by expanding the mask.
- Using a Gaussian blur can cause banding artifacts. Gaussian blur doesn't have a "size" or "radius" parameter in the sense that you think it should. It's a convolution matrix and there are _no non-zero values in the result_. This means that, far away from the mask, once compositing completes, we have some values that are very close to zero but not quite zero. These values are quantized by HTML Canvas, resulting in banding artifacts where you'd expect the blur to have faded to 0% alpha. At least, that is my understanding of why the banding artifacts occur.
The new node uses a better strategy to expand the mask and add the fade out effect:
- Calculate the distance from each white pixel to the nearest black pixel.
- Normalize this distance by dividing by the fade size in px, then clip the values to 0 - 1. The result represents the distance of each white pixel to its nearest black pixel as a percentage of the fade size. At this point, it is a linear distribution.
- Create a polynomial to describe the fade's intensity so that we can have a smooth transition from the masked region (black) to unmasked (white). There are some magic numbers here, deterined experimentally.
- Evaluate the polynomial over the normalized distances, so we now have a matrix representing the fade intensity for every pixel
- Convert this matrix back to uint8 and apply it to the mask
This works soooo much better than the previous method. Not only does it fix the banding issues, but when we enable "output only generated regions", we get a much smaller image. Will add images to the PR to clarify.
## Summary

## Summary
**Problem**
We want to have automated tests for model classification/probing, but
model files are too large to include in the source.
**Proposed Solution**
Classification/probing only requires metadata (key names, tensor
shapes), not weights.
This PR introduces "stripped" models - lightweight versions that retains
only essential metadata.
- Added script to strip models
- Added stripped models to automated tests
**Model size before and after "stripping":**

## Summary
The _goal_ of this PR is to make it easier to add an new config type.
This _scope_ of this PR is to integrate the API and does not include
adding new configs (outside tests) or porting existing ones.
One of the glaring issues of the existing *legacy probe* is that the
logic for each type is spread across multiple classes and intertwined
with the other configs. This means that adding a new config type (or
modifying an existing one) is complex and error prone.
This PR attempts to remedy this by providing a new API for adding
configs that:
- Is backwards compatible with the existing probe.
- Encapsulates fields and logic in a single class, keeping things
self-contained and easy to modify safely.
Below is a minimal toy example illustrating the proposed new structure:
```python
class MinimalConfigExample(ModelConfigBase):
type: ModelType = ModelType.Main
format: ModelFormat = ModelFormat.Checkpoint
fun_quote: str
@classmethod
def matches(cls, mod: ModelOnDisk) -> bool:
return mod.path.suffix == ".json"
@classmethod
def parse(cls, mod: ModelOnDisk) -> dict[str, Any]:
with open(mod.path, "r") as f:
contents = json.load(f)
return {
"fun_quote": contents["quote"],
"base": BaseModelType.Any,
}
```
To create a new config type, one needs to inherit from `ModelConfigBase`
and implement its interface.
The code falls back to the legacy model probe for existing models using
the old API.
This allows us to incrementally port the configs one by one.

In #7688 we optimized queuing preparation logic. This inadvertently broke retrying queue items.
Previously, a `NamedTuple` was used to store the values to insert in the DB when enqueuing. This handy class provides an API similar to a dataclass, where you can instantiate it with kwargs in any order. The resultant tuple re-orders the kwargs to match the order in the class definition.
For example, consider this `NamedTuple`:
```py
class SessionQueueValueToInsert(NamedTuple):
foo: str
bar: str
```
When instantiating it, no matter the order of the kwargs, if you make a normal tuple out of it, the tuple values are in the same order as in the class definition:
```
t1 = SessionQueueValueToInsert(foo="foo", bar="bar")
print(tuple(t1)) # -> ('foo', 'bar')
t2 = SessionQueueValueToInsert(bar="bar", foo="foo")
print(tuple(t2)) # -> ('foo', 'bar')
```
So, in the old code, when we used the `NamedTuple`, it implicitly normalized the order of the values we insert into the DB.
In the retry logic, the values of the tuple were not ordered correctly, but the use of `NamedTuple` had secretly fixed the order for us.
In the linked PR, `NamedTuple` was dropped for a normal tuple, after profiling showed `NamedTuple` to be meaningfully slower than a normal tuple.
The implicit order normalization behaviour wasn't understood, and the order wasn't fixed when changin the retry logic to use a normal tuple instead of `NamedTuple`. This results in a bug where we incorrectly create queue items in the DB. For example, we stored the `destination` in the `field_values` column.
When such an incorrectly-created queue item is dequeued, it fails pydantic validation and causes what appears to be an endless loop of errors.
The only user-facing solution is to add this line to `invokeai.yaml` and restart the app:
```yaml
clear_queue_on_startup: true
```
On next startup, the queue is forcibly cleared before the error loop is triggered. Then the user should remove this line so their queue is persisted across app launches per usual.
The solution is simple - fix the ordering of the tuple. I also added a type annotation and comment to the tuple type alias definition.
Note: The endless error loop, as a general problem, will take some thinking to fix. The queue service methods to cancel and fail a queue item still retrieve it and parse it. And the list queue items methods parse the queue items. Bit of a catch 22, maybe the solution is to simply delete totally borked queue items and log an error.

This document describes the implementation of user isolation features in the InvokeAI session queue and processing system to address issues identified in the enhancement request.
## Issues Addressed
### 1. Cross-User Image/Preview Visibility
**Problem:** When two users are logged in simultaneously and one initiates a generation, the generation preview shows up in both users' browsers and the generated image gets saved to both users' image boards.
**Solution:** Implemented socket-level event filtering based on user authentication:
**Problem:** When the job queue tab is open in multiple browsers and a generation is begun in one browser window, the queue does not update in the other window.
**Status:** This issue is likely resolved by the socket authentication and event filtering changes. The existing socket subscription mechanism (`subscribe_queue` event) already supports multiple connections per user. Testing is required to confirm this works correctly with the new authentication flow.
### 4. User Information Display

Canvas Projects provide a save/load mechanism for the entire canvas state. The feature serializes all canvas entities, generation parameters, reference images, and their associated image files into a ZIP-based `.invk` file. On load, it restores the full state, handling image deduplication and re-uploading as needed.
## File Format
The `.invk` file is a standard ZIP archive with the following structure:
```
project.invk
├── manifest.json
├── canvas_state.json
├── params.json
├── ref_images.json
├── loras.json
└── images/
├── {image_name_1}.png
├── {image_name_2}.png
└── ...
```
### manifest.json
Schema version and metadata. Validated on load with Zod.
```json
{
"version":1,
"appVersion":"5.12.0",
"createdAt":"2026-02-26T12:00:00.000Z",
"name":"My Canvas Project"
}
```
| Field | Type | Description |
|---|---|---|
| `version` | `number` | Schema version, currently `1`. Used for migration logic on load. |
| `appVersion` | `string` | InvokeAI version that created the file. Informational only. |
| `createdAt` | `string` | ISO 8601 timestamp. |
| `name` | `string` | User-provided project name. Also used as the download filename. |
### canvas_state.json
The serialized canvas entity tree. Type: `CanvasProjectState`.
Each entity contains its full state including all canvas objects (brush lines, eraser lines, rect shapes, images). Image objects reference files by `image_name` which correspond to files in the `images/` folder.
### params.json
The complete generation parameters state (`ParamsState`). Optional on load (older files may not have it). This includes all fields from the params Redux slice:
- Seamless tiling, mask blur, CLIP skip, VAE precision, CPU noise, color compensation
### ref_images.json
Global reference image entities (`RefImageState[]`). These are IP-Adapter / FLUX Redux configs with `CroppableImageWithDims` containing both original and cropped image references. Optional on load.
### loras.json
Array of LoRA configurations (`LoRA[]`). Each entry contains:
```typescript
typeLoRA={
id: string;
isEnabled: boolean;
model: ModelIdentifierField;
weight: number;
};
```
Optional on load. Like models, LoRA identifiers are stored as-is — if a LoRA is not installed when loading, the entry is restored but may not be usable.
### images/
All image files referenced anywhere in the state. Keyed by their original `image_name`. On save, each image is fetched from the backend via `GET /api/v1/images/i/{name}/full` and stored as-is.
## Key Source Files
| File | Purpose |
|---|---|
| `features/controlLayers/util/canvasProjectFile.ts` | Types, constants, image name collection, remapping, existence checking |
| `features/controlLayers/hooks/useCanvasProjectSave.ts` | Save hook — collects Redux state, fetches images, builds ZIP |
The `canvasProjectFile.ts` utility provides two parallel sets of functions:
**Collection** (`collectImageNames`): Walks the entire state tree and returns a `Set<string>` of all referenced `image_name` values. This is used by both save (to know which images to fetch) and load (to know which images to check/upload).
**Remapping** (`remapCanvasState`, `remapRefImages`): Deep-clones state objects and replaces `image_name` values using a `Map<string, string>` mapping. Only images that were re-uploaded with a different name are remapped. Images that already existed on the server are left unchanged.
- Global ref images → `CroppableImageWithDims.original.image.image_name` and `.crop.image.image_name`
## Extending the Format
### Adding new optional data (non-breaking)
Add a new JSON file to the ZIP. No version bump needed.
1.**Save**: Add `zip.file('new_data.json', JSON.stringify(data))` in `useCanvasProjectSave.ts`
2.**Load**: Read with `zip.file('new_data.json')` in `useCanvasProjectLoad.ts` — check for `null` so older project files without it still load
3.**Dispatch**: Add the appropriate Redux action to restore the data
### Adding new entity types with images
1. Extend `CanvasProjectState` type in `canvasProjectFile.ts`
2. Add collection logic in `collectImageNames()` to walk the new entity's objects
3. Add remapping logic in `remapCanvasState()` to update image names
4. Include the new entity array in both save and load hooks
5. Handle it in the `canvasProjectRecalled` reducer in `canvasSlice.ts`
### Breaking schema changes
1. Bump `CANVAS_PROJECT_VERSION` in `canvasProjectFile.ts`
2. Update the Zod manifest schema: `version: z.union([z.literal(1), z.literal(2)])`
3. Add migration logic in the load hook: check version, transform v1 → v2 before dispatching
## UI Architecture
### Save dialog
The save flow uses a **nanostore atom** (`$isOpen`) to control the `SaveCanvasProjectDialog`:
1.`useSaveCanvasProjectWithDialog()` — returns a callback that sets `$isOpen` to `true`
2.`SaveCanvasProjectDialog` (singleton in `GlobalModalIsolator`) — renders an `AlertDialog` with a name input
3. On save → calls `saveCanvasProject(name)` and closes the dialog
4. On cancel → closes the dialog
### Load dialog
The load flow uses a **nanostore atom** (`$pendingFile`) to decouple the file dialog from the confirmation dialog:
1.`useLoadCanvasProjectWithDialog()` — opens a programmatic file input (`document.createElement('input')`)
2. On file selection → sets `$pendingFile` atom
3.`LoadCanvasProjectConfirmationAlertDialog` (singleton in `GlobalModalIsolator`) — subscribes to `$pendingFile` via `useStore()`
4. On accept → calls `loadCanvasProject(file)` and clears the atom
5. On cancel → clears the atom
The programmatic file input approach was chosen because the context menu component uses `isLazy: true`, which unmounts the DOM tree when the menu closes — a hidden `<input>` element inside the menu would be destroyed before the file dialog returns.
This document outlines the process for reviewing and merging pull requests (PRs) into the InvokeAI repository.
## Review Process
### 1. Assignment
One of the repository maintainers will assign collaborators to review a pull request. The assigned reviewer(s) will be responsible for conducting the code review.
### 2. Review and Iteration
The assignee is responsible for:
- Reviewing the PR thoroughly
- Providing constructive feedback
- Iterating with the PR author until the assignee is satisfied that the PR is fit to merge
- Ensuring the PR meets code quality standards, follows project conventions, and doesn't introduce bugs or regressions
### 3. Approval and Notification
Once the assignee is satisfied with the PR:
- The assignee approves the PR
- The assignee alerts one of the maintainers that the PR is ready for merge using the **#request-reviews Discord channel**
### 4. Final Merge
One of the maintainers is responsible for:
- Performing a final check of the PR
- Merging the PR into the appropriate branch
**Important:** Collaborators are strongly discouraged from merging PRs on their own, except in case of emergency (e.g., critical bug fix and no maintainer is available).
### 5. Release Policy
Once a feature release candidate is published, no feature PRs are to
be merged into main. Only bugfixes are allowed until the final
release.
## Best Practices
### Clean Commit History
To encourage a clean development log, PR authors are encouraged to use `git rebase -i` to suppress trivial commit messages (e.g., `ruff` and `prettier` formatting fixes) after the PR is accepted but before it is merged.
### Merge Strategy
The maintainer will perform either a **3-way merge** or **squash merge** when merging a PR into the `main` branch. This approach helps avoid rebase conflict hell and maintains a cleaner project history.
### Attribution
The PR author should reference any papers, source code or
documentation that they used while creating the code both in the PR
and as comments in the code itself. If there are any licensing
restrictions, these should be linked to and/or reproduced in the repo
root.
## Summary
This policy ensures that:
- All PRs receive proper review from assigned collaborators
- Maintainers have final oversight before code enters the main branch
- The commit history remains clean and meaningful
- Merge conflicts are minimized through appropriate merge strategies
# Recall Parameters API - LoRAs, ControlNets, and IP Adapters with Images
## Overview
The Recall Parameters API supports recalling LoRAs, ControlNets (including T2I Adapters and Control LoRAs), and IP Adapters along with their associated weights and settings. Control Layers and IP Adapters can now include image references from the `INVOKEAI_ROOT/outputs/images` directory for fully functional control and image prompt functionality.
## Key Features
✅ **LoRAs**: Fully functional - adds to UI, queries model configs, applies weights
✅ **Control Layers**: Full support with optional images from outputs/images
✅ **IP Adapters**: Full support with optional reference images from outputs/images
✅ **Model Name Resolution**: Automatic lookup from human-readable names to internal keys
✅ **Image Validation**: Backend validates that image files exist before sending
## Endpoints

A new REST API endpoint has been added to the InvokeAI backend that allows programmatic updates to recallable parameters from another process. This enables external applications or scripts to modify frontend parameters like prompts, models, and step counts via HTTP requests.
When parameters are updated via the API, the backend automatically broadcasts a WebSocket event to all connected frontend clients subscribed to that queue, causing them to update immediately.
## How It Works
1.**API Request**: External application sends a POST request with parameters to update
2.**Storage**: Parameters are stored in client state persistence, associated with a queue ID
3.**Broadcast**: A WebSocket event (`recall_parameters_updated`) is emitted to all frontend clients listening to that queue
4.**Frontend Update**: Connected frontend clients receive the event and can process the updated parameters
5.**Immediate Display**: The frontend UI updates automatically with the new values
This means if you have the InvokeAI frontend open in a browser, updating parameters via the API will instantly reflect on the screen without any manual action needed.

- Provides the font dropdown, size slider/input, formatting toggles, and alignment buttons that appear when the Text tool is active.
## Rasterization pipeline
`renderTextToCanvas()` (`invokeai/frontend/web/src/features/controlLayers/text/textRenderer.ts`) converts the editor contents into a transparent canvas. The Text tool module configures the renderer with the active font stack, weight, styling flags, alignment, and the active canvas color. The resulting canvas is encoded to a PNG data URL and stored in a new raster layer (`image` object) with a transparent background.
Layer placement preserves the original click location:
- The session stores the anchor coordinate (where the user clicked) and current alignment.
-`calculateLayerPosition()` calculates the top-left position for the raster layer after applying the configured padding and alignment offsets.
- New layers are inserted directly above the currently-selected raster layer (when present) and selected automatically.
## Font stacks
Font definitions live in `invokeai/frontend/web/src/features/controlLayers/text/textConstants.ts` as ten deterministic stacks (sans, serif, mono, rounded, script, humanist, slab serif, display, narrow, UI serif). Each stack lists system-safe fallbacks so the editor can choose the first available font per platform.
To add or adjust fonts:
1. Update `TEXT_FONT_STACKS` with the new `id`, `label`, and CSS `font-family` stack.
2. If you add a new stack, extend the `TEXT_FONT_IDS` tuple and update the `canvasTextSlice` schema default (`TEXT_DEFAULT_FONT_ID`).
3. Provide translation strings for any new labels in `public/locales/*`.
4. The editor and renderer will automatically pick up the new stack via `getFontStackById()`.

The Text tool uses a set of predefined font stacks. When you choose a font, the app resolves the first available font on your system from that stack and uses it for both the editor overlay and the rasterized result. This provides consistent styling across platforms while still falling back to safe system fonts if a preferred font is missing.
## Size and spacing
- **Size** controls the font size in pixels.
- **Spacing** controls the line height multiplier (Dense, Normal, Spacious). This affects the distance between lines while editing the text.

## How to Save a Project
You can save from two places:
1.**Toolbar** — Click the **Archive icon** in the canvas toolbar, then select **Save Canvas Project**
2.**Context menu** — Right-click the canvas, open the **Project** submenu, then select **Save Canvas Project**
A dialog will ask you to enter a **project name**. This name is used as the filename (e.g., entering "My Portrait" saves as `My Portrait.invk`) and is stored inside the project file.
## How to Load a Project
1.**Toolbar** — Click the **Archive icon**, then select **Load Canvas Project**
2.**Context menu** — Right-click the canvas, open the **Project** submenu, then select **Load Canvas Project**
A file dialog will open. Select your `.invk` file. You will see a confirmation dialog warning that loading will replace your current canvas. Click **Load** to proceed.
### What Happens on Load
- Your current canvas is **completely replaced** — all existing layers, masks, reference images, and parameters are overwritten
- Images that are already present on your InvokeAI server are reused automatically (no duplicate uploads)
- Images that were deleted from the server are re-uploaded from the project file
- If the saved model is not installed on your system, the model identifier is still restored — you will need to select an available model manually
## Good to Know
- **No undo** — Loading a project replaces your canvas entirely. There is no way to undo this action, so save your current project first if you want to keep it.
- **Image deduplication** — When loading, images already on your server are not re-uploaded. Only missing images are uploaded from the project file.
- **File size** — The `.invk` file size depends on the number and resolution of images in your canvas. A project with many high-resolution layers can be large.
- **Model availability** — The project saves which model was selected, but does not include the model itself. If the model is not installed when you load the project, you will need to select a different one.
- **Persistent Settings**: Your custom hotkeys are saved and restored across sessions
- **Easy Reset**: Reset individual hotkeys or all hotkeys back to defaults
## How to Use
### Opening the Hotkeys Modal
Press `Shift+?` or click the keyboard icon in the application to open the Hotkeys Modal.
### Viewing Hotkeys
In **View Mode** (default), you can:
- Browse all available hotkeys organized by category (App, Canvas, Gallery, Workflows, etc.)
- Search for specific hotkeys using the search bar
- See the current key combination for each action
### Customizing Hotkeys
1. Click the **Edit Mode** button at the bottom of the Hotkeys Modal
2. Find the hotkey you want to change
3. Click the **pencil icon** next to it
4. The editor will appear with:
- **Input field**: Enter your new hotkey combination
- **Modifier buttons**: Quick-insert Mod, Ctrl, Shift, Alt keys
- **Help icon** (?): Shows syntax examples and valid keys
- **Live preview**: See how your hotkey will look
5. Enter your new hotkey using the format:
-`mod+a` - Mod key + A (Mod = Ctrl on Windows/Linux, Cmd on Mac)
-`ctrl+shift+k` - Multiple modifiers
-`f1` - Function keys
-`mod+enter, ctrl+enter` - Multiple alternatives (separated by comma)
6. Click the **checkmark** or press Enter to save
7. Click the **X** or press Escape to cancel
### Resetting Hotkeys
**Reset a single hotkey:**
- Click the counter-clockwise arrow icon that appears next to customized hotkeys
**Reset all hotkeys:**
- In Edit Mode, click the **Reset All to Default** button at the bottom
### Hotkey Format Reference
**Valid Modifiers:**
-`mod` - Context-aware: Ctrl (Windows/Linux) or Cmd (Mac)
-`ctrl` - Control key
-`shift` - Shift key
-`alt` - Alt key (Option on Mac)
**Valid Keys:**
- Letters: `a-z`
- Numbers: `0-9`
- Function keys: `f1-f12`
- Special keys: `enter`, `space`, `tab`, `backspace`, `delete`, `escape`
- Arrow keys: `up`, `down`, `left`, `right`
- And more...
**Examples:**
- ✅ `mod+s` - Save action
- ✅ `ctrl+shift+p` - Command palette
- ✅ `f5, mod+r` - Two alternatives for refresh
- ❌ `mod+` - Invalid (no key after modifier)
- ❌ `shift+ctrl+` - Invalid (ends with modifier)
## For Developers
For technical implementation details, architecture, and how to add new hotkeys to the system, see the [Hotkeys Developer Documentation](../contributing/HOTKEYS.md).
This feature adds a UI for synchronizing the models directory by finding and removing orphaned model files. Orphaned models are directories that contain model files but are not referenced in the InvokeAI database.
We recommend using the Invoke Launcher to install and update Invoke. It's a desktop application for Windows, macOS and Linux. It takes care of a lot of nitty gritty details for you.
Follow the [quick start guide](./quick_start.md) to get started.
!!! tip "Use the installer to update"
Using the installer for updates will not erase any of your data (images, models, boards, etc). It only updates the core libraries used to run Invoke.
Simply use the same path you installed to originally to update your existing installation.
Both release and pre-release versions can be installed using the installer. It also supports install through a wheel if needed.
Be sure to review the [installation requirements] and ensure your system has everything it needs to install Invoke.
## Getting the Latest Installer
Download the `InvokeAI-installer-vX.Y.Z.zip` file from the [latest release] page. It is at the bottom of the page, under **Assets**.
After unzipping the installer, you should have a `InvokeAI-Installer` folder with some files inside, including `install.bat` and `install.sh`.
## Running the Installer
!!! tip
Windows users should first double-click the `WinLongPathsEnabled.reg` file to prevent a failed installation due to long file paths.
Double-click the install script:
=== "Windows"
```sh
install.bat
```
=== "Linux/macOS"
```sh
install.sh
```
!!! info "Running the Installer from the commandline"
You can also run the install script from cmd/powershell (Windows) or terminal (Linux/macOS).
!!! warning "Untrusted Publisher (Windows)"
You may get a popup saying the file comes from an `Untrusted Publisher`. Click `More Info` and `Run Anyway` to get past this.
The installation process is simple, with a few prompts:
- Select the version to install. Unless you have a specific reason to install a specific version, select the default (the latest version).
- Select location for the install. Be sure you have enough space in this folder for the base application, as described in the [installation requirements].
- Select a GPU device.
!!! info "Slow Installation"
The installer needs to download several GB of data and install it all. It may appear to get stuck at 99.9% when installing `pytorch` or during a step labeled "Installing collected packages".
If it is stuck for over 10 minutes, something has probably gone wrong and you should close the window and restart.
## Running the Application
Find the install location you selected earlier. Double-click the launcher script to run the app:
=== "Windows"
```sh
invoke.bat
```
=== "Linux/macOS"
```sh
invoke.sh
```
Choose the first option to run the UI. After a series of startup messages, you'll see something like this:
```sh
Uvicorn running on http://127.0.0.1:9090 (Press CTRL+C to quit)
```
Copy the URL into your browser and you should see the UI.
## Improved Outpainting with PatchMatch
PatchMatch is an extra add-on that can improve outpainting. Windows users are in luck - it works out of the box.
On macOS and Linux, a few extra steps are needed to set it up. See the [PatchMatch installation guide](./patchmatch.md).
## First-time Setup
You will need to [install some models] before you can generate.
Check the [configuration docs] for details on configuring the application.
## Updating
Updating is exactly the same as installing - download the latest installer, choose the latest version, enter your existing installation path, and the app will update. None of your data (images, models, boards, etc) will be erased.
!!! info "Dependency Resolution Issues"
We've found that pip's dependency resolution can cause issues when upgrading packages. One very common problem was pip "downgrading" torch from CUDA to CPU, but things broke in other novel ways.
The installer doesn't have this kind of problem, so we use it for updating as well.
## Installation Issues
If you have installation issues, please review the [FAQ]. You can also [create an issue] or ask for help on [discord].

This guide is for administrators managing a multi-user InvokeAI installation. It covers initial setup, user management, security best practices, and troubleshooting.
## Prerequisites
Before enabling multi-user support, ensure you have:
- InvokeAI installed and running
- Access to the server filesystem (for initial setup)
- Understanding of your deployment environment
- Backup of your existing data (recommended)
## Initial Setup
### Activating Multiuser Mode
To put InvokeAI into multiuser mode, you will need to add the option
`multiuser: true` to its configuration file. This file is located at
`INVOKEAI_ROOT/invokeai.yaml` With the InvokeAI backend halted, add
the new configuration option to the end of the file with a text editor
so that it looks like this:
```yaml
# Internal metadata - do not edit:
schema_version:4.0.2
# Enable/disable multi-user mode
multiuser:true
```
Then restart the InvokeAI server backend from the command line or
using the launcher.
!!! note "Reverting to single-user mode"
If at any time you wish to revert to single-user mode, simply comment
out the `multiuser` line, or change "true" to "false". Then
restart the server. Because of the way that browsers cache pages,
users with open InvokeAI sessions may need to force-refresh their
browsers.
### First Administrator Account
When InvokeAI starts for the first time in multi-user mode, you'll see the **Administrator Setup** dialog.
**Setup Steps:**
1.**Email Address**: Enter a valid email address (this becomes your username)
* Example: `admin@example.com` or `admin@localhost` for testing
* Must be a valid email format
* Cannot be changed later without database access
2.**Display Name**: Enter a friendly name
* Example: "System Administrator" or your real name
* Can be changed later in your profile
* Visible to other users in shared contexts
3.**Password**: Create a strong administrator password
* **Minimum requirements:**
* At least 8 characters long
* Contains uppercase letters (A-Z)
* Contains lowercase letters (a-z)
* Contains numbers (0-9)
* **Recommended:**
* Use 12+ characters
* Include special characters (!@#$%^&*)
* Use a password manager to generate and store
* Don't reuse passwords from other services
4.**Confirm Password**: Re-enter the password
5. Click **Create Administrator Account**
!!! warning "Important"
Store these credentials securely! The
first administrator account can reset
the password to something new, but cannot
retrieve a lost one.
### Configuration
InvokeAI can run in single-user or multi-user mode, controlled by the `multiuser` configuration option in `invokeai.yaml`:
**Single-User Mode** (`multiuser: false` or option absent):
- No authentication required
- All functionality enabled by default
- All boards and images visible in unified view
- Ideal for personal use or trusted environments
**Multi-User Mode** (`multiuser: true`):
- Authentication required for access
- User isolation for boards, images, and workflows
- Role-based permissions enforced
- Ideal for shared servers or team environments
!!! warning "Mode Switching Behavior"
**Switching to Single-User Mode:** If boards or images were created in multi-user mode, they will all be combined into a single unified view when switching to single-user mode.
**Switching to Multi-User Mode:** Legacy boards and images created under single-user mode will be owned by an internal user named "system." Only the Administrator will have access to these legacy assets. A utility to migrate these legacy assets to another user will be part of a future release.
### Migration from Single-User
When upgrading from a single-user installation or switching modes:
1.**Automatic Migration**: The database will automatically migrate to multi-user schema when multi-user mode is first enabled
2.**Legacy Data Ownership**: Existing data (boards, images, workflows) created in single-user mode is assigned to an internal user named "system"
3.**Administrator Access**: Only administrators will have access to legacy "system"-owned assets when in multi-user mode
4.**No Data Loss**: All existing content is preserved
A utility to migrate legacy "system"-owned assets to specific user accounts will be available in a future release. Until then, administrators can access and manage all legacy content.
## User Management
### Creating Users
**Via Web Interface (Coming Soon):**
!!! info "Web UI for User Management"
A web-based user interface that allows administrators to manage users is coming in a future release. Until then, use the command-line scripts described below.
**Via Command Line Scripts:**
InvokeAI provides several command-line scripts in the `scripts/` directory for user management:
**useradd.py** - Add a new user:
```bash
# Interactive mode (prompts for details)
python scripts/useradd.py
# Create a regular user
python scripts/useradd.py \
--email user@example.com \
--password TempPass123 \
--name "User Name"
# Create an administrator
python scripts/useradd.py \
--email admin@example.com \
--password AdminPass123 \
--name "Admin Name"\
--admin
```
**userlist.py** - List all users:
```bash
# List all users
python scripts/userlist.py
# Show detailed information
python scripts/userlist.py --verbose
```
**usermod.py** - Modify an existing user:
```bash
# Change display name
python scripts/usermod.py --email user@example.com --name "New Name"

# InvokeAI Multi-User Support - Detailed Specification
## 1. Executive Summary
This document provides a comprehensive specification for adding multi-user support to InvokeAI. The feature will enable a single InvokeAI instance to support multiple isolated users, each with their own generation settings, image boards, and workflows, while maintaining administrative controls for model management and system configuration.
## 2. Overview
### 2.1 Goals
- Enable multiple users to share a single InvokeAI instance
- Provide user isolation for personal content (boards, images, workflows, settings)
- Maintain centralized model management by administrators
- Support shared boards for collaboration
- Provide secure authentication and authorization
- Minimize impact on existing single-user installations
### 2.2 Non-Goals
- Real-time collaboration features (multiple users editing same workflow simultaneously)
- Advanced team management features (in initial release)
- Migration of existing multi-user enterprise edition data
- Support for external identity providers (in initial release, can be added later)
## 3. User Roles and Permissions
### 3.1 Administrator Role
**Capabilities:**
- Full access to all InvokeAI features
- Model management (add, delete, configure models)
- User management (create, edit, delete users)
- View and manage all users' queue sessions
- Access system configuration
- Create and manage shared boards
- Grant/revoke administrative privileges to other users
**Restrictions:**
- Cannot delete their own account if they are the last administrator
- Cannot revoke their own admin privileges if they are the last administrator
### 3.2 Regular User Role
**Capabilities:**
- Create, edit, and delete their own image boards
- Upload and manage their own assets
- Use all image generation tools (linear, canvas, upscale, workflow tabs)
- Create, edit, save, and load workflows
- Access public/shared workflows
- View and manage their own queue sessions
- Adjust personal UI preferences (theme, hotkeys, etc.)
- Access shared boards (read/write based on permissions)
- **View model configurations** (read-only access to model manager)
- **View model details, default settings, and metadata**
**Restrictions:**
- Cannot add, delete, or edit models
- **Can view but cannot modify model manager settings** (read-only access)
- Cannot reidentify, convert, or update model paths
- Cannot upload or change model thumbnail images
- Cannot save changes to model default settings
- Cannot perform bulk delete operations on models
- Cannot view or modify other users' boards, images, or workflows
- Cannot cancel or modify other users' queue sessions
**Note**: Email/SMTP configuration is optional. Many administrators will not have ready access to an outgoing SMTP server. When email is not configured, the system provides fallback mechanisms by displaying setup links directly in the admin UI.

- [ ] Non-admin users cannot access model management
- [ ] Queue filtering works correctly for users and admins
- [ ] Session management works correctly (expiry, renewal, logout)
- [ ] All security tests pass
- [ ] API documentation is updated
- [ ] User and admin documentation is complete
- [ ] Migration from single-user works smoothly
- [ ] Performance is acceptable with multiple concurrent users
- [ ] Backward compatibility mode works (auth disabled)
## 19. Design Decisions
The following design decisions have been approved for implementation:
1.**OAuth2 Priority**: OAuth2/OpenID Connect integration will be a **future enhancement**. The initial release will focus on username/password authentication to keep scope manageable.
2.**Email Requirement**: Email/SMTP configuration is **optional**. Many administrators will not have ready access to an outgoing SMTP server. The system will provide fallback mechanisms (showing setup links directly in the admin UI) when email is not configured.
3.**Data Migration**: During migration from single-user to multi-user mode, the administrator will be given the **option to specify an arbitrary user account** to hold legacy data. The admin account can be used for this purpose if the administrator wishes.
4.**API Compatibility**: Authentication will be **required on all APIs**, but authentication will not be required if multi-user support is disabled (backward compatibility mode with `auth_enabled: false`).
5.**Session Storage**: The system will use **JWT tokens with optional server-side session tracking**. This provides scalability while allowing administrators to enable server-side tracking if needed.
6.**Audit Logging**: The system will **log authentication events and admin actions**. This provides accountability and security monitoring for critical operations.
## 20. Conclusion
This specification provides a comprehensive blueprint for implementing multi-user support in InvokeAI. The design prioritizes:
- **Security**: Proper authentication, authorization, and data isolation
- **Flexibility**: Future enhancement paths, optional features
The phased implementation approach allows for iterative development and testing, while the detailed specifications ensure all stakeholders have clear expectations of the final system.
Multi-User mode is a recent feature (introduced in version 6.12), which allows multiple individuals to share a single InvokeAI server while keeping their work separate and organized. Each user has their own username and login password, images, assets, image boards, customization settings and workflows.
Two types of users are recognized:
* A user with **Administrator** status can add, remove and modify other users, and can install models. They also have the ability to view the full session queue and pause or kill other users' jobs.
* **Non-administrator** users can modify their own profile but not others. They also do not have the ability to install or configure models, but must ask an Administrator to do this task.
Multiple users can be granted Administrator status.
***
## Getting Started
To activate Multi-User mode, open the `INVOKEAI_ROOT/invokeai.yaml` configuration file in a text editor. Add this line anywhere in the file:
```yaml
multiuser:true
```
You may also wish to make InvokeAI available to other machines on your local LAN. Add an additional line to `invokeai.yaml`:
```yaml
host:0.0.0.0
```
Restart the server. It will now be in multi-user mode. If you enabled
the `host` option, other users on your home or office LAN will be able
to reach it by browsing to the IP address of the machine the backend
is running on (`http://host-ip-address:9090`).
!!! tip "Do not expose InvokeAI to the internet"
It is not recommended to expose the InvokeAI host to the internet
due to security concerns.
### Initial Setup (First Time in Multi-User Mode)
If you're the first person to access a fresh InvokeAI installation in multi-user mode, you'll see the **Administrator Setup** dialog:
1. Enter your email address (this will be your login name)
2. Create a display name (this will be the name other users see)
3. Choose a strong password that meets the requirements:
- At least 8 characters long
- Contains uppercase letters
- Contains lowercase letters
- Contains numbers
4. Confirm your password
5. Click **Create Administrator Account**
You'll now be taken to a login screen and can enter the credentials
you just created.
### Adding and Modifying Users
If you are logged in as Administrator, you can add additional users. Click on the small "person silhouette" icon at the bottom left of the main Invoke screen and select "User Management:"
...where you can click "Create User" to add a new user.
The User Management screen also allows you to:
1. Temporarily change a user's status to Inactive, preventing them from logging in to Invoke.
2. Edit a user (by clicking on the pencil icon) to change the user's display name or password.
3. Permanently delete a user.
4. Grant a user Administrator privileges.
### Command-line User Management Scripts
Administrators can also use a series of command-line scripts to add, modify, or delete users. If you use the launcher, click the ">" icon to enter the command-line interface. Otherwise, if you are a native command-line user, activate the InvokeAI environment from your terminal.
The commands are named:
* **invoke-useradd** -- add a user
* **invoke-usermod** -- modify a user
* **invoke-userdel** -- delete a user
* **invoke-userlist** -- list all users
Pass the `--help` argument to get the usage of each script. For example:
--root ROOT, -r ROOT Path to the InvokeAI root directory. If omitted, the root is resolved in this order: the $INVOKEAI_ROOT environment
variable, the active virtual environment's parent directory, or $HOME/invokeai.
--email EMAIL, -e EMAIL
User email address
--password PASSWORD, -p PASSWORD
User password
--name NAME, -n NAME User display name (optional)
--admin, -a Make user an administrator
If no arguments are provided, the script will run in interactive mode.
```
***
## Logging in as a Non-Administrative User
If you are a registered user on the system, enter your email address and password to log in. The Administrator will be able to provide you with the values to use:
As an unprivileged user you can do pretty much anything that's allowed under single-user mode -- generating images, using LoRAs, creating and running workflows, creating image boards -- but you are restricted against installing new models, changing low-level server settings, or interfering with other users. More information on user roles is given below.
### Changing your Profile
To change your display name or profile, click on the person silhouette icon at the bottom left of the screen and choose "My Profile". This will take you to a screen that lets you change these values. At this time you can change your display name but not your login ID (ordinarily your contact email address).
***
## Understanding User Roles
In single-user mode, you have access to all features without restrictions. In multi-user mode, InvokeAI has two user roles:
### Regular User
As a regular user, you can:
- ✅ Create and manage your own image boards
- ✅ Generate images using all AI tools (Linear, Canvas, Upscale, Workflows)
- ✅ Create, save, and load your own workflows
- ✅ View your own generation queue
- ✅ Customize your UI preferences (theme, hotkeys, etc.)
- ✅ View available models (read-only access to Model Manager)
- ✅ View shared and public boards created by other users
- ✅ View and use workflows marked as shared by other users
You cannot:
- ❌ Add, delete, or modify models
- ❌ View or modify other users' private boards, images, or workflows
- ❌ Manage user accounts
- ❌ Access system configuration
- ❌ View or cancel other users' generation tasks
!!! tip "The generation queue"
When two or more users are accessing InvokeAI at the same time,
their image generation jobs will be placed on the session queue on
a first-come, first-serve basis. This means that you will have to
wait for other users' image rendering jobs to complete before
yours will start.
When another user's job is running, you will see the image
generation progress bar and a queue badge that reads `X/Y`, where
"X" is the number of jobs you have queued and "Y" is the total
number of jobs queued, including your own and others.
You can also pull up the Queue tab in order to see where your job
is in relationship to other queued tasks.
### Administrator
Administrators have all regular user capabilities, plus:
- ✅ Full model management (add, delete, configure models)
- ✅ Create and manage user accounts
- ✅ View and manage all users' generation queues
- ✅ View and manage all users' boards, images, and workflows (including system-owned legacy content)
- ✅ Access system configuration
- ✅ Grant or revoke admin privileges
***
## Working with Your Content in Multi-User Mode
### Image Boards
In multi-user mode, each user can create an unlimited number of boards and organize their images and assets as they see fit. Boards have three visibility levels:
- **Private** (default): Only you (and administrators) can see and modify the board.
- **Shared**: All users can view the board and its contents, but only you (and administrators) can modify it (rename, archive, delete, or add/remove images).
- **Public**: All users can view the board. Only you (and administrators) can modify the board's structure (rename, archive, delete).
To change a board's visibility, right-click on the board and select the desired visibility option.
Administrators can see and manage all users' image boards and their contents regardless of visibility settings.
### Going From Multi-User to Single-User Mode
If an InvokeAI instance was in multiuser mode and then restarted in single user mode (by setting `multiuser: false` in the configuration file), all users' boards will be consolidated in one place. Any images that were in "Uncategorized" will be merged together into a single Uncategorized board. If, at a later date, the server is restarted in multi-user mode, the boards and images will be separated and restored to their owners.
### Workflows
Each user has their own private workflow library. Workflows you create are visible only to you by default.
You can share a workflow with other users by marking it as **shared** (public). Shared workflows appear in all users' workflow libraries and can be opened by anyone, but only the owner (or an administrator) can modify or delete them.
To share a workflow, open it and use the sharing controls to toggle its public/shared status.
!!! warning "Preexisting workflows after enabling multi-user mode"
When you enable multi-user mode for the first time on an existing InvokeAI installation, all workflows that were created before multi-user mode was activated will appear in the **shared workflows** section. These preexisting workflows are owned by the internal "system" account and are visible to all users. Administrators can edit or delete these shared legacy workflows. Regular users can view and use them but cannot modify them.
### The Generation Queue
The queue shows your pending and running generation tasks.
**Queue Features:**
- View your current and completed generations
- Cancel pending tasks
- Re-run previous generations
- Monitor progress in real-time
**Queue Isolation:**
- You will see your own queue items, as well as the items generated by
either users, but the generation parameters (e.g. prompts) for other
users' are hidden for privacy reasons.
- Administrators can view all queues for troubleshooting
- Your generations won't interfere with other users' tasks
***
## Customizing Your Experience
### Personal Preferences
Your UI preferences are saved to your account and are restored when you log in:
- **Theme**: Choose between light and dark modes
- **Hotkeys**: Customize keyboard shortcuts
- **Canvas Settings**: Default zoom, grid visibility, etc.
- **Generation Defaults**: Default values for width, height, steps, etc.
These settings are stored per-user and won't affect other users.
***
## Troubleshooting
### Cannot Log In
**Issue:** Login fails with "Incorrect email or password"
**Solutions:**
- Verify you're entering the correct email address
- Check that Caps Lock is off
- Try typing the password slowly to avoid mistakes
- Contact your administrator if you've forgotten your password
**Issue:** Login fails with "Account is disabled"
**Solution:** Contact your administrator to reactivate your account
### Session Expired
**Issue:** You're suddenly logged out and see "Session expired"
**Explanation:** Sessions expire after 24 hours (or 7 days with "remember me")
**Solution:** Simply log in again with your credentials
### Cannot Access Features
**Issue:** Features like Model Manager show "Admin privileges required"
**Explanation:** Some features are restricted to administrators
**Solution:**
- For model viewing: You can view but not modify models
- For user management: Contact an administrator
- For system configuration: Contact an administrator
### Missing Boards or Images
**Issue:** Boards or images you created are not visible
**Possible Causes:**
1.**Filter Applied:** Check if a filter is hiding content
2.**Wrong User:** Ensure you're logged in with the correct account
3.**Archived Board:** Check the "Show Archived" option
**Solution:**
- Clear any active filters
- Verify you're logged in as the right user
- Check archived items
### Slow Performance
**Issue:** Generation or UI feels slower than expected
**Possible Causes:**
- Other users generating images simultaneously
- Server resource limits
- Network latency
**Solutions:**
- Check the queue to see if others are generating
- Wait for current generations to complete
- Contact administrator if persistent
### Generation Stuck in Queue
**Issue:** Your generation is queued but not starting
**Possible Causes:**
- Server is processing other users' generations
- Server resources are fully utilized
- Technical issue with the server
**Solutions:**
- Wait for your turn in the queue
- Check if your generation is paused
- Contact administrator if stuck for extended period

## Frequently Asked Questions
### Can other users see my images?
Not unless you change your board's visibility to "shared" or "public". All personal boards and images are private by default.
### Can I share my workflows with others?
Yes. You can mark any workflow as shared (public), which makes it visible to all users. Other users can view and use shared workflows, but only you or an administrator can modify or delete them.
### How long do sessions last?
- 24 hours by default
- 7 days if you check "Remember me" during login
### Can I use the API with multi-user mode?
Yes, but you'll need to authenticate with a JWT token. See the [API Guide](api_guide.md) for details.
### What happens if I forget my password?
Contact your administrator. They can reset your password for you.
### Can I have multiple sessions?
Yes, you can log in from multiple devices or browsers simultaneously. All sessions will use the same account and see the same content.
### Why can't I see the Model Manager "Add Models" tab?
Regular users can see the Models tab but with read-only access. Check that you're logged in and try refreshing the page.
### How do I know if I'm an administrator?
Administrators see an "Admin" badge next to their name in the top-right corner and have access to additional features like User Management.
### Can I request admin privileges?
Yes, ask your current administrator to grant you admin
privileges. Admin privileges will give you the ability to see all
other user's boards and images, as well as to add models and change
various server-wide settings.
