 # @tanstack/ai-anthropic
 
+## 0.23.0
+
+### Minor Changes
+
+- [#1837](https://github.com/TanStack/ai/pull/1837) [`824ee98`](https://github.com/TanStack/ai/commit/824ee98060983dd2b5728f288cecefa6a1250325) - Add computer use that runs the same code on OpenAI and on Anthropic. A driver controls the machine. The Playwright and sandbox drivers give each thread its own machine.
+
+  New packages:
+  - `@tanstack/ai-computer-use` adds `createComputerUse()`. It returns `tools`, a middleware, a safety-check interrupt, and `close`. Each `threadId` gets its own machine, action queue, and approvals. A thread that stays idle for `idleTimeout` (10 minutes by default) closes.
+  - `@tanstack/ai-computer-playwright` adds `playwrightComputer()`, which opens one browser page for each thread. `createPlaywrightComputerDriver()` controls one page that you give it. Both add a `navigate` tool that opens `http:` and `https:` URLs.
+  - `@tanstack/ai-computer-sandbox` adds `sandboxComputer()`, which creates one Linux desktop sandbox for each thread from any `@tanstack/ai-sandbox` provider, like `e2bSandbox({ template: 'desktop' })`. `createSandboxComputerDriver()` controls one sandbox that you give it.
+  - `@tanstack/ai-computer-local` adds `localComputer()`, which lets the model use the mouse, keyboard, and main screen of the machine that runs `chat()`. It works on Windows, macOS, and Linux with `@jitsi/robotjs`.
+
+  Changes in existing packages:
+  - `@tanstack/ai` adds `threadId` to `ToolExecutionContext`. It also adds the computer tool metadata reader in `@tanstack/ai/adapter-internals`.
+  - `@tanstack/ai-anthropic` and `@tanstack/openai-base` send the generic computer tool to the model as the native computer tool of the provider.
+  - `@tanstack/ai-openai` marks the models that support the `computer` tool.
+
+  ```ts
+  const computerUse = createComputerUse({
+    driver: playwrightComputer({ startUrl: 'https://tanstack.com' }),
+  })
+
+  chat({
+    adapter,
+    messages,
+    threadId,
+    tools: computerUse.tools,
+    middleware: [computerUse.middleware],
+    interrupts: [computerUse.interrupt],
+  })
+
+  await computerUse.close(threadId) // one thread
+  await computerUse.close() // every thread, and the browser
+  ```
+
+  The `ai-core` agent skill routes computer use to `@tanstack/ai-computer-use` and its three drivers.
+
+- [#1837](https://github.com/TanStack/ai/pull/1837) [`824ee98`](https://github.com/TanStack/ai/commit/824ee98060983dd2b5728f288cecefa6a1250325) - Run computer use on every Claude model that supports it.
+  - `computerUseTool()` takes `computer_toolset_20260801`, the only computer use version of Claude Opus 5.5, Sonnet 5.5, and Haiku 5.5. The model calls each action as its own tool. The adapter runs each call as one `computer` call with the action in `input.action`, and sends it back to Claude in the form that Claude sent. So one `execute` works for every version.
+  - `computerUseTool()` takes `computer_20251124`, with its `computer-use-2025-11-24` beta header.
+  - Each model now takes only the computer use versions that it supports. For example, `computer_20250124` on `claude-opus-4-6` is a type error, because Anthropic rejects that pair.
+  - `@anthropic-ai/sdk` is now `^0.135.0`.

Before, a request with the tool had no computer use beta, so Anthropic rejected it.
