-## Running node_modules binaries

-1. **Preferred** — spawn the executable directly from `node_modules/.bin/<tool>` (or the platform equivalent on Windows). This is what `script/lint.js` does for `oxlint`.
-2. **Acceptable** — invoke via `yarn <tool>` or `yarn run <tool>`, which resolves to the locally installed version without the registry fallback that `npx` performs.

+description: Handle built-in AI APIs with a local LLM implementation
+slug: local-ai-handler
+hide_title: true
+---
+
+# Local AI Handler
+
+> **This API is experimental.** It may change or be removed in future Electron releases.
+
+Electron supports [Prompt API](https://github.com/webmachinelearning/prompt-api)
+(`LanguageModel`) web API by letting you route calls to a local LLM running in a
+[utility process](../api/utility-process.md). Web content calls
+`LanguageModel.create()` and `LanguageModel.prompt()` like it would in any
+browser, while your Electron app decides which model handles the request.
+
+## How it works
+
+The local AI handler architecture involves three processes:
+
+1. **Main process** — creates `UtilityProcess`, and then registers it to handle
+   Prompt API calls for a given session via [`ses.registerLocalAIHandler()`](../api/session.md#sesregisterlocalaihandlerhandler-experimental).
+2. **Utility process** — runs a script that calls
+   [`localAIHandler.setPromptAPIHandler()`](../api/local-ai-handler.md#localaihandlersetpromptapihandlerhandler-experimental)
+   to supply a `LanguageModel` subclass.
+3. **Renderer process** — web content uses the standard `LanguageModel` API
+   (e.g. `LanguageModel.create()`, `model.prompt()`).
+
+When a renderer calls the Prompt API, Electron proxies the request through the
+main process to the registered utility process, which invokes your
+`LanguageModel` implementation and sends the result back directly to the renderer.
+
+## Prerequisites
+
+The Prompt API Blink feature must be enabled on any `BrowserWindow` that will
+use it with the `AIPromptAPI` feature. To enable multi-modal inputs, add the
+`AIPromptAPIMultimodalInput` as well.
+
+```js
+const win = new BrowserWindow({
+  webPreferences: {
+    enableBlinkFeatures: 'AIPromptAPI'
+  }
+})
+```
+
+## Quick start
+
+### 1. Create the utility process script
+
+The utility process script registers your `LanguageModel` subclass. The
+handler function receives a `details` object with information about the
+caller, and must return a class that extends `LanguageModel`.
+
+```js title='ai-handler.js (Utility Process)'
+const { localAIHandler, LanguageModel } = require('electron/utility')
+
+localAIHandler.setPromptAPIHandler((details) => {
+  // details.webContentsId — ID of the calling WebContents
+  // details.securityOrigin — origin of the calling page
+
+  return class MyLanguageModel extends LanguageModel {
+    static async create (options) {
+      // options.signal - AbortSignal to cancel the creation of the model
+      // options.initialPrompts - initial prompts to pass to the language model
+
+      return new MyLanguageModel({
+        contextUsage: 0,
+        contextWindow: 4096
+      })
+    }
+
+    static async availability () {
+      // Return 'available', 'downloadable', 'downloading', or 'unavailable'
+      return 'available'
+    }
+
+    async prompt (input) {
+      // input is a string or LanguageModelMessage[]
+      // Return a string response from your model, or a ReadableStream
+      // to return a streaming response.
+      return 'This is a response from your local LLM!'
+    }
+
+    async clone () {
+      return new MyLanguageModel({
+        contextUsage: this.contextUsage,
+        contextWindow: this.contextWindow
+      })
+    }
+
+    destroy () {
+      // Clean up model resources
+    }
+  }
+})
+```
+
+### 2. Register the handler in the main process
+
+Fork the utility process and register it as the AI handler for a session:
+
+```js title='main.js (Main Process)'
+const { app, BrowserWindow, utilityProcess } = require('electron')
+
+const path = require('node:path')
+
+app.whenReady().then(() => {
+  // Fork the utility process running your AI handler script
+  const aiHandler = utilityProcess.fork(path.join(__dirname, 'ai-handler.js'))
+
+  // Create a window with the Prompt API enabled
+  const win = new BrowserWindow({
+    webPreferences: {
+      enableBlinkFeatures: 'AIPromptAPI'
+    }
+  })
+
+  // Connect the AI handler to this session
+  win.webContents.session.registerLocalAIHandler(aiHandler)
+
+  win.loadFile('index.html')
+})
+```
+
+### 3. Use the Prompt API in your renderer
+
+Your web content can now use the standard `LanguageModel` API, which is a
+global available in the renderer:
+
+```html title='index.html (Renderer Process)'
+<script>
+async function askAI () {
+  const model = await LanguageModel.create()
+  const response = await model.prompt('What is Electron?')
+  document.getElementById('response').textContent = response
+}
+</script>
+
+<button onclick="askAI()">Ask AI</button>
+<p id="response"></p>
+```
+
+## Implementing a real model
+
+The quick-start example returns a hardcoded string. A real implementation
+would integrate with a local model. See [`electron/llm`](https://github.com/electron/llm)
+for an example of using `node-llama-cpp` to wire up GGUF (GPT-Generated Unified Format) models.
+
+## Clearing the handler
+
+To disconnect the AI handler from a session, pass `null`:
+
+```js @ts-type={win:Electron.BrowserWindow}
+win.webContents.session.registerLocalAIHandler(null)
+```
+
+After clearing, any `LanguageModel.create()` calls from renderers using that
+session will fail.
+
+## Security considerations
+
+The `details` object passed to your handler includes `webContentsId` and
+`securityOrigin`. Use these to decide whether to handle a request, and
+when to reuse a model instance versus providing a fresh instance to
+provide proper isolation between origins.

patches/chromium/disable_compositor_recycling.patch

@@ -6,10 +6,10 @@ Subject: fix: disabling compositor recycling
 Compositor recycling is useful for Chrome because there can be many tabs and spinning up a compositor for each one would be costly. In practice, Chrome uses the parent compositor code path of browser_compositor_view_mac.mm; the NSView of each tab is detached when it's hidden and attached when it's shown. For Electron, there is no parent compositor, so we're forced into the "own compositor" code path, which seems to be non-optimal and pretty ruthless in terms of the release of resources. Electron has no real concept of multiple tabs per window, so it should be okay to disable this ruthless recycling altogether in Electron.

@@ -7,10 +7,10 @@ Subject: feat: filter out non-shareable windows in the current application in
 This patch ensures that windows protected via win.setContentProtection(true) do not appear in full display captures via desktopCapturer.  This patch could be upstreamed but as the check is limited to in-process windows it doesn't make a lot of sense for Chromium itself.  This patch currently has a limitation that it only function for windows created / protected BEFORE the stream is started.  There is theoretical future work we can do via polling / observers to automatically update the SCContentFilter when new windows are made but for now this will solve 99+% of the problem and folks can re-order their logic a bit to get it working for their use cases.
