-
-The `inplace` field controls how local model Paths are handled. If
-True (the default), then the model is simply registered in its current
-location by the installer's `ModelConfigRecordService`. Otherwise, a
-copy of the model put into the location specified by the `models_dir`
-application configuration parameter.
-
-The `variant` field is used for HuggingFace repo_ids only. If
-provided, the repo_id download handler will look for and download
-tensors files that follow the convention for the selected variant:
-
-- "fp16" will select files named "*model.fp16.{safetensors,bin}"
-- "onnx" will select files ending with the suffix ".onnx"
-- "openvino" will select files beginning with "openvino_model"
-
-In the special case of the "fp16" variant, the installer will select
-the 32-bit version of the files if the 16-bit version is unavailable.
-
-`subfolder` is used for HuggingFace repo_ids only. If provided, the
-model will be downloaded from the designated subfolder rather than the
-top-level repository folder. If a subfolder is attached to the repo_id
-using the format `repo_owner/repo_name:subfolder`, then the subfolder
-specified by the repo_id will override the subfolder argument.
+The next few sections describe the various types of ModelSource that
+can be passed to `import_model()`. 
 
 `config` can be used to override all or a portion of the configuration
 attributes returned by the model prober. See the section below for
 details.
 
-`access_token` is passed to the download queue and used to access
-repositories that require it.

+This is used for a model that is located on a locally-accessible Posix
+filesystem, such as a local disk or networked fileshare.

+
+#### URLModelSource
+
+This is used for a single-file model that is accessible via a URL. The
+fields are:
+
+| **Argument**     | **Type**                     | **Default** | **Description**                           |

+
+The `AnyHttpUrl` class can be imported from `pydantic.networks`.
+
+Ordinarily, no metadata is retrieved from these sources. However,
+there is special-case code in the installer that looks for HuggingFace
+and Civitai URLs and fetches the corresponding model metadata from
+the corresponding repo.

+#### CivitaiModelSource
+
+This is used for a model that is hosted by the Civitai web site.

+| `version_id`     | int                          | None        | The ID of the particular version of the desired model. |
+| `access_token`   | str                          | None        | An access token needed to gain access to a subscriber's-only model. |
+
+Civitai has two model IDs, both of which are integers. The `model_id`
+corresponds to a collection of model versions that may different in
+arbitrary ways, such as derivation from different checkpoint training
+steps, SFW vs NSFW generation, pruned vs non-pruned, etc. The
+`version_id` points to a specific version. Please use the latter.
+
+Some Civitai models require an access token to download. These can be
+generated from the Civitai profile page of a logged-in
+account. Somewhat annoyingly, if you fail to provide the access token
+when downloading a model that needs it, Civitai generates a redirect
+to a login page rather than a 403 Forbidden error. The installer
+attempts to catch this event and issue an informative error
+message. Otherwise you will get an "unrecognized model suffix" error
+when the model prober tries to identify the type of the HTML login
+page.
+
+#### HFModelSource
+
+HuggingFace has the most complicated `ModelSource` structure:
+
+| **Argument**     | **Type**                     | **Default** | **Description**                           |
+|------------------|------------------------------|-------------|-------------------------------------------|
+| `repo_id`        | str                          | None        | The ID of the desired model. |
+| `variant`        | ModelRepoVariant             | ModelRepoVariant('fp16')      | The desired variant. |
+| `subfolder`      | Path                         | None        | Look for the model in a subfolder of the repo. |
+| `access_token`   | str                          | None        | An access token needed to gain access to a subscriber's-only model. |
+
+
+The `repo_id` is the repository ID, such as `stabilityai/sdxl-turbo`.
+
+The `variant` is one of the various diffusers formats that HuggingFace
+supports and is used to pick out from the hodgepodge of files that in
+a typical HuggingFace repository the particular components needed for
+a complete diffusers model. `ModelRepoVariant` is an enum that can be
+imported from `invokeai.backend.model_manager` and has the following
+values:
+
+| **Name**                   | **String Value**          |
+|----------------------------|---------------------------|
+| ModelRepoVariant.DEFAULT   | "default"                 |
+| ModelRepoVariant.FP16      | "fp16"                 |
+| ModelRepoVariant.FP32      | "fp32"                 |
+| ModelRepoVariant.ONNX      | "onnx"                 |
+| ModelRepoVariant.OPENVINO  | "openvino"             |
+| ModelRepoVariant.FLAX      | "flax"                 |
+
+You can also pass the string forms to `variant` directly. Note that
+InvokeAI may not be able to load and run all variants. At the current
+time, specifying `ModelRepoVariant.DEFAULT` will retrieve model files
+that are unqualified, e.g. `pytorch_model.safetensors` rather than
+`pytorch_model.fp16.safetensors`. These are usually the 32-bit
+safetensors forms of the model.
+
+If `subfolder` is specified, then the requested model resides in a
+subfolder of the main model repository. This is typically used to
+fetch and install VAEs.
+
+Some models require you to be registered with HuggingFace and logged
+in. To download these files, you must provide an
+`access_token`. Internally, if no access token is provided, then
+`HfFolder.get_token()` will be called to fill it in with the cached
+one.

-# The remainder of this documentation is provisional, pending implementation of the Download and Load services
-
-## Let's get loaded, the lowdown on ModelLoadService
-
-The `ModelLoadService` is responsible for loading a named model into
-memory so that it can be used for inference. Despite the fact that it
-does a lot under the covers, it is very straightforward to use.
-
-An application-wide model loader is created at API initialization time
-and stored in
-`ApiDependencies.invoker.services.model_loader`. However, you can
-create alternative instances if you wish.
-
-### Creating a ModelLoadService object
-
-The class is defined in
-`invokeai.app.services.model_loader_service`. It is initialized with
-an InvokeAIAppConfig object, from which it gets configuration
-information such as the user's desired GPU and precision, and with a
-previously-created `ModelRecordServiceBase` object, from which it
-loads the requested model's configuration information.
-
-Here is a typical initialization pattern:
-
-```
-from invokeai.app.services.config import InvokeAIAppConfig
-from invokeai.app.services.model_record_service import ModelRecordServiceBase
-from invokeai.app.services.model_loader_service import ModelLoadService
-
-config = InvokeAIAppConfig.get_config()
-store = ModelRecordServiceBase.open(config)
-loader = ModelLoadService(config, store)
-```
-
-Note that we are relying on the contents of the application
-configuration to choose the implementation of
-`ModelRecordServiceBase`.
-
-### get_model(key, [submodel_type], [context]) -> ModelInfo:
-
-*** TO DO: change to get_model(key, context=None, **kwargs)
-
-The `get_model()` method, like its similarly-named cousin in
-`ModelRecordService`, receives the unique key that identifies the
-model.  It loads the model into memory, gets the model ready for use,
-and returns a `ModelInfo` object. 
-
-The optional second argument, `subtype` is a `SubModelType` string
-enum, such as "vae". It is mandatory when used with a main model, and
-is used to select which part of the main model to load.
-
-The optional third argument, `context` can be provided by
-an invocation to trigger model load event reporting. See below for
-details.
-
-The returned `ModelInfo` object shares some fields in common with
-`ModelConfigBase`, but is otherwise a completely different beast:
-
-| **Field Name** | **Type**        |  **Description** |
-|----------------|-----------------|------------------|
-| `key`          | str                    | The model key derived from the ModelRecordService database |
-| `name`         | str                    | Name of this model |
-| `base_model`   | BaseModelType          | Base model for this model |
-| `type`         | ModelType or SubModelType   | Either the model type (non-main) or the submodel type (main models)|
-| `location`     | Path or str            | Location of the model on the filesystem |
-| `precision`    | torch.dtype            | The torch.precision to use for inference |
-| `context`      | ModelCache.ModelLocker | A context class used to lock the model in VRAM while in use |
-
-The types for `ModelInfo` and `SubModelType` can be imported from
-`invokeai.app.services.model_loader_service`.
-
-To use the model, you use the `ModelInfo` as a context manager using
-the following pattern:
-
-```
-model_info = loader.get_model('f13dd932c0c35c22dcb8d6cda4203764', SubModelType('vae'))
-with model_info as vae:
-	image = vae.decode(latents)[0]
-```
-
-The `vae` model will stay locked in the GPU during the period of time
-it is in the context manager's scope.
-
-`get_model()` may raise any of the following exceptions:
-
-- `UnknownModelException`  -- key not in database
-- `ModelNotFoundException` -- key in database but model not found at path
-- `InvalidModelException`  -- the model is guilty of a variety of sins
-  
-** TO DO: ** Resolve discrepancy between ModelInfo.location and
-ModelConfig.path.
-
-### Emitting model loading events
-
-When the `context` argument is passed to `get_model()`, it will

+## This Meta be Good: Model Metadata Storage
+
+The modules found under `invokeai.backend.model_manager.metadata`
+provide a straightforward API for fetching model metadatda from online
+repositories. Currently two repositories are supported: HuggingFace
+and Civitai. However, the modules are easily extended for additional
+repos, provided that they have defined APIs for metadata access.
+
+Metadata comprises any descriptive information that is not essential
+for getting the model to run. For example "author" is metadata, while
+"type", "base" and "format" are not. The latter fields are part of the
+model's config, as defined in `invokeai.backend.model_manager.config`.
+
+### Example Usage:
+
+```
+from invokeai.backend.model_manager.metadata import (
+   AnyModelRepoMetadata,
+   CivitaiMetadataFetch,
+   CivitaiMetadata
+   ModelMetadataStore,
+)
+# to access the initialized sql database
+from invokeai.app.api.dependencies import ApiDependencies
+
+civitai = CivitaiMetadataFetch()
+
+# fetch the metadata
+model_metadata = civitai.from_url("https://civitai.com/models/215796")
+
+# get some common metadata fields
+author = model_metadata.author
+tags = model_metadata.tags
+
+# get some Civitai-specific fields
+assert isinstance(model_metadata, CivitaiMetadata)
+
+trained_words = model_metadata.trained_words
+base_model = model_metadata.base_model_trained_on
+thumbnail = model_metadata.thumbnail_url
+
+# cache the metadata to the database using the key corresponding to
+# an existing model config record in the `model_config` table
+sql_cache = ModelMetadataStore(ApiDependencies.invoker.services.db)
+sql_cache.add_metadata('fb237ace520b6716adc98bcb16e8462c', model_metadata)
+
+# now we can search the database by tag, author or model name
+# matches will contain a list of model keys that match the search
+matches = sql_cache.search_by_tag({"tool", "turbo"})
+```
+
+### Structure of the Metadata objects
+
+There is a short class hierarchy of Metadata objects, all of which
+descend from the Pydantic `BaseModel`.
+
+#### `ModelMetadataBase`
+
+This is the common base class for metadata:
+
+| **Field Name** | **Type**        |  **Description** |
+|----------------|-----------------|------------------|
+| `name`        | str           | Repository's name for the model |
+| `author`      | str           | Model's author |
+| `tags`        | Set[str]      | Model tags |
+
+
+Note that the model config record also has a `name` field. It is
+intended that the config record version be locally customizable, while
+the metadata version is read-only. However, enforcing this is expected
+to be part of the business logic.
+
+Descendents of the base add additional fields.
+
+#### `HuggingFaceMetadata`
+
+This descends from `ModelMetadataBase` and adds the following fields:
+
+| **Field Name** | **Type**        |  **Description** |
+|----------------|-----------------|------------------|
+| `type`         | Literal["huggingface"]   | Used for the discriminated union of metadata classes|
+| `id`           | str              | HuggingFace repo_id |
+| `tag_dict`     | Dict[str, Any]   | A dictionary of tag/value pairs provided in addition to `tags` |
+| `last_modified`| datetime         | Date of last commit of this model to the repo |
+| `files`        | List[Path]       | List of the files in the model repo |
+
+
+#### `CivitaiMetadata`
+
+This descends from `ModelMetadataBase` and adds the following fields:
+
+| **Field Name** | **Type**        |  **Description** |
+|----------------|-----------------|------------------|
+| `type`         | Literal["civitai"]   | Used for the discriminated union of metadata classes|
+| `id`           | int                  | Civitai model id |
+| `version_name` | str                  | Name of this version of the model (distinct from model name) |
+| `version_id`   | int                  | Civitai model version id (distinct from model id) |
+| `created`      | datetime             | Date this version of the model was created |
+| `updated`      | datetime             | Date this version of the model was last updated |
+| `published`    | datetime             | Date this version of the model was published to Civitai |
+| `description`  | str                  | Model description. Quite verbose and contains HTML tags |
+| `version_description` | str           | Model version description, usually describes changes to the model |
+| `nsfw`         | bool                 | Whether the model tends to generate NSFW content |
+| `restrictions` | LicenseRestrictions  | An object that describes what is and isn't allowed with this model |
+| `trained_words`| Set[str]             | Trigger words for this model, if any |
+| `download_url` | AnyHttpUrl           | URL for downloading this version of the model |
+| `base_model_trained_on` | str         | Name of the model that this version was trained on |
+| `thumbnail_url` | AnyHttpUrl          | URL to access a representative thumbnail image of the model's output |
+| `weight_min`    | int                 | For LoRA sliders, the minimum suggested weight to apply |
+| `weight_max`    | int                 | For LoRA sliders, the maximum suggested weight to apply |
+
+Note that `weight_min` and `weight_max` are not currently populated
+and take the default values of (-1.0, +2.0). The issue is that these
+values aren't part of the structured data but appear in the text
+description. Some regular expression or LLM coding may be able to
+extract these values.
+
+Also be aware that `base_model_trained_on` is free text and doesn't
+correspond to our `ModelType` enum.
+
+`CivitaiMetadata` also defines some convenience properties relating to
+licensing restrictions: `credit_required`, `allow_commercial_use`,
+`allow_derivatives` and `allow_different_license`.
+
+#### `AnyModelRepoMetadata`
+
+This is a discriminated Union of `CivitaiMetadata` and
+`HuggingFaceMetadata`.
+
+### Fetching Metadata from Online Repos
+
+The `HuggingFaceMetadataFetch` and `CivitaiMetadataFetch` classes will
+retrieve metadata from their corresponding repositories and return
+`AnyModelRepoMetadata` objects. Their base class
+`ModelMetadataFetchBase` is an abstract class that defines two
+methods: `from_url()` and `from_id()`. The former accepts the type of
+model URLs that the user will try to cut and paste into the model
+import form. The latter accepts a string ID in the format recognized
+by the repository of choice. Both methods return an
+`AnyModelRepoMetadata`.
+
+The base class also has a class method `from_json()` which will take
+the JSON representation of a `ModelMetadata` object, validate it, and
+return the corresponding `AnyModelRepoMetadata` object.
+
+When initializing one of the metadata fetching classes, you may
+provide a `requests.Session` argument. This allows you to customize
+the low-level HTTP fetch requests and is used, for instance, in the
+testing suite to avoid hitting the internet.
+
+The HuggingFace and Civitai fetcher subclasses add additional
+repo-specific fetching methods:
+
+
+#### HuggingFaceMetadataFetch
+
+This overrides its base class `from_json()` method to return a
+`HuggingFaceMetadata` object directly.
+
+#### CivitaiMetadataFetch
+
+This adds the following methods:
+
+`from_civitai_modelid()` This takes the ID of a model, finds the
+default version of the model, and then retrieves the metadata for
+that version, returning a `CivitaiMetadata` object directly.
+
+`from_civitai_versionid()` This takes the ID of a model version and
+retrieves its metadata. Functionally equivalent to `from_id()`, the
+only difference is that it returna a `CivitaiMetadata` object rather
+than an `AnyModelRepoMetadata`.
+
+
+### Metadata Storage
+
+The `ModelMetadataStore` provides a simple facility to store model
+metadata in the `invokeai.db` database. The data is stored as a JSON
+blob, with a few common fields (`name`, `author`, `tags`) broken out
+to be searchable. 
+
+When a metadata object is saved to the database, it is identified
+using the model key, _and this key must correspond to an existing
+model key in the model_config table_. There is a foreign key integrity
+constraint between the `model_config.id` field and the
+`model_metadata.id` field such that if you attempt to save metadata
+under an unknown key, the attempt will result in an
+`UnknownModelException`. Likewise, when a model is deleted from
+`model_config`, the deletion of the corresponding metadata record will
+be triggered.
+
+Tags are stored in a normalized fashion in the tables `model_tags` and
+`tags`. Triggers keep the tag table in sync with the `model_metadata`
+table.
+
+To create the storage object, initialize it with the InvokeAI
+`SqliteDatabase` object. This is often done this way:
+
+```
+from invokeai.app.api.dependencies import ApiDependencies
+metadata_store = ModelMetadataStore(ApiDependencies.invoker.services.db)
+```
+
+You can then access the storage with the following methods:
+
+#### `add_metadata(key, metadata)`
+
+Add the metadata using a previously-defined model key.
+
+There is currently no `delete_metadata()` method. The metadata will
+persist until the matching config is deleted from the `model_config`
+table.
+
+#### `get_metadata(key) -> AnyModelRepoMetadata`
+
+Retrieve the metadata corresponding to the model key.
+
+#### `update_metadata(key, new_metadata)`
+
+Update an existing metadata record with new metadata.
+
+#### `search_by_tag(tags: Set[str]) -> Set[str]`
+
+Given a set of tags, find models that are tagged with them. If
+multiple tags are provided then a matching model must be tagged with
+*all* the tags in the set. This method returns a set of model keys and
+is intended to be used in conjunction with the `ModelRecordService`:
+
+```
+model_config_store = ApiDependencies.invoker.services.model_records
+matches = metadata_store.search_by_tag({'license:other'})
+models = [model_config_store.get(x) for x in matches]
+```
+
+#### `search_by_name(name: str) -> Set[str]
+
+Find all model metadata records that have the given name and return a
+set of keys to the corresponding model config objects.
+
+#### `search_by_author(author: str) -> Set[str]
+
+Find all model metadata records that have the given author and return
+a set of keys to the corresponding model config objects.
+
+# The remainder of this documentation is provisional, pending implementation of the Load service
+
+## Let's get loaded, the lowdown on ModelLoadService
+
+The `ModelLoadService` is responsible for loading a named model into
+memory so that it can be used for inference. Despite the fact that it
+does a lot under the covers, it is very straightforward to use.
+
+An application-wide model loader is created at API initialization time
+and stored in
+`ApiDependencies.invoker.services.model_loader`. However, you can
+create alternative instances if you wish.
+
+### Creating a ModelLoadService object
+
+The class is defined in
+`invokeai.app.services.model_loader_service`. It is initialized with
+an InvokeAIAppConfig object, from which it gets configuration
+information such as the user's desired GPU and precision, and with a
+previously-created `ModelRecordServiceBase` object, from which it
+loads the requested model's configuration information.
+
+Here is a typical initialization pattern:
+
+```
+from invokeai.app.services.config import InvokeAIAppConfig
+from invokeai.app.services.model_record_service import ModelRecordServiceBase
+from invokeai.app.services.model_loader_service import ModelLoadService
+
+config = InvokeAIAppConfig.get_config()
+store = ModelRecordServiceBase.open(config)
+loader = ModelLoadService(config, store)
+```
+
+Note that we are relying on the contents of the application
+configuration to choose the implementation of
+`ModelRecordServiceBase`.
+
+### get_model(key, [submodel_type], [context]) -> ModelInfo:
+
+*** TO DO: change to get_model(key, context=None, **kwargs)
+
+The `get_model()` method, like its similarly-named cousin in
+`ModelRecordService`, receives the unique key that identifies the
+model.  It loads the model into memory, gets the model ready for use,
+and returns a `ModelInfo` object. 
+
+The optional second argument, `subtype` is a `SubModelType` string
+enum, such as "vae". It is mandatory when used with a main model, and
+is used to select which part of the main model to load.
+
+The optional third argument, `context` can be provided by
+an invocation to trigger model load event reporting. See below for
+details.
+
+The returned `ModelInfo` object shares some fields in common with
+`ModelConfigBase`, but is otherwise a completely different beast:
+
+| **Field Name** | **Type**        |  **Description** |
+|----------------|-----------------|------------------|
+| `key`          | str                    | The model key derived from the ModelRecordService database |
+| `name`         | str                    | Name of this model |
+| `base_model`   | BaseModelType          | Base model for this model |
+| `type`         | ModelType or SubModelType   | Either the model type (non-main) or the submodel type (main models)|
+| `location`     | Path or str            | Location of the model on the filesystem |
+| `precision`    | torch.dtype            | The torch.precision to use for inference |
+| `context`      | ModelCache.ModelLocker | A context class used to lock the model in VRAM while in use |
+
+The types for `ModelInfo` and `SubModelType` can be imported from
+`invokeai.app.services.model_loader_service`.
+
+To use the model, you use the `ModelInfo` as a context manager using
+the following pattern:
+
+```
+model_info = loader.get_model('f13dd932c0c35c22dcb8d6cda4203764', SubModelType('vae'))
+with model_info as vae:
+	image = vae.decode(latents)[0]
+```
+
+The `vae` model will stay locked in the GPU during the period of time
+it is in the context manager's scope.
+
+`get_model()` may raise any of the following exceptions:
+
+- `UnknownModelException`  -- key not in database
+- `ModelNotFoundException` -- key in database but model not found at path
+- `InvalidModelException`  -- the model is guilty of a variety of sins
+  
+** TO DO: ** Resolve discrepancy between ModelInfo.location and
+ModelConfig.path.
+
+### Emitting model loading events
+
+When the `context` argument is passed to `get_model()`, it will
+retrieve the invocation event bus from the passed `InvocationContext`
+object to emit events on the invocation bus. The two events are
+"model_load_started" and "model_load_completed". Both carry the
+following payload:
+
+```
+payload=dict(
+	queue_id=queue_id,
+	queue_item_id=queue_item_id,
+	queue_batch_id=queue_batch_id,
+	graph_execution_state_id=graph_execution_state_id,
+	model_key=model_key,
+	submodel=submodel,
+	hash=model_info.hash,
+	location=str(model_info.location),
+	precision=str(model_info.precision),
+)
+```

-
-The UI is a fairly straightforward Typescript React app, with the Unified Canvas being more complex.
-
-Code is located in `invokeai/frontend/web/` for review.
-
-## Stack
-
-State management is Redux via [Redux Toolkit](https://github.com/reduxjs/redux-toolkit). We lean heavily on RTK:
-
-- `createAsyncThunk` for HTTP requests
-- `createEntityAdapter` for fetching images and models
-- `createListenerMiddleware` for workflows
-
-The API client and associated types are generated from the OpenAPI schema. See API_CLIENT.md.
-
-Communication with server is a mix of HTTP and [socket.io](https://github.com/socketio/socket.io-client) (with a simple socket.io redux middleware to help).
-
-[Chakra-UI](https://github.com/chakra-ui/chakra-ui) & [Mantine](https://github.com/mantinedev/mantine) for components and styling.
-
-[Konva](https://github.com/konvajs/react-konva) for the canvas, but we are pushing the limits of what is feasible with it (and HTML canvas in general). We plan to rebuild it with [PixiJS](https://github.com/pixijs/pixijs) to take advantage of WebGL's improved raster handling.
-
-[Vite](https://vitejs.dev/) for bundling.
-
-Localisation is via [i18next](https://github.com/i18next/react-i18next), but translation happens on our [Weblate](https://hosted.weblate.org/engage/invokeai/) project. Only the English source strings should be changed on this repo.
-
-## Contributing
-
-Thanks for your interest in contributing to the InvokeAI Web UI!
-
-We encourage you to ping @psychedelicious and @blessedcoolant on [Discord](https://discord.gg/ZmtBAhwWhy) if you want to contribute, just to touch base and ensure your work doesn't conflict with anything else going on. The project is very active.
-
-### Dev Environment
-
-**Setup** 
-
-1. Install [node](https://nodejs.org/en/download/). You can confirm node is installed with:
-```bash
-node --version
-```
-
-2. Install [pnpm](https://pnpm.io/) and confirm it is installed by running this:
-```bash
-npm install --global pnpm
-pnpm --version
-```
-
-From `invokeai/frontend/web/` run `pnpm install` to get everything set up.
-
-Start everything in dev mode:
-1. Ensure your virtual environment is running
-2. Start the dev server: `pnpm dev`
-3. Start the InvokeAI Nodes backend: `python scripts/invokeai-web.py # run from the repo root`
-4. Point your browser to the dev server address e.g. [http://localhost:5173/](http://localhost:5173/)
-
-### VSCode Remote Dev
-
-We've noticed an intermittent issue with the VSCode Remote Dev port forwarding. If you use this feature of VSCode, you may intermittently click the Invoke button and then get nothing until the request times out. Suggest disabling the IDE's port forwarding feature and doing it manually via SSH:
-
-`ssh -L 9090:localhost:9090 -L 5173:localhost:5173 user@host`
-
-### Production builds
-
-For a number of technical and logistical reasons, we need to commit UI build artefacts to the repo.
-
-If you submit a PR, there is a good chance we will ask you to include a separate commit with a build of the app.
-
-To build for production, run `pnpm build`.

+
+### Nodes
+
+Behind the scenes, InvokeAI has been completely rewritten to support
+"nodes," small unitary operations that can be combined into graphs to
+form arbitrary workflows. For example, there is a prompt node that
+processes the prompt string and feeds it to a text2latent node that
+generates a latent image. The latents are then fed to a latent2image
+node that translates the latent image into a PNG.
+
+The WebGUI has a node editor that allows you to graphically design and

 It is common to want to use both the same seed (for continuity) and random seeds (for variety). To define a seed, simply enter it into the 'Seed' field on a noise node. Conversely, the RandomInt node generates a random integer between 'Low' and 'High', and can be used as input to the 'Seed' edge point on a noise node to randomize your seed.
