36 - On the Claude API and Claude Models on Google Cloud (Google managed), Claude 5.5 and later models support computer use only through the `computer_toolset_20260801` toolset and return an error for the earlier `computer_20251124` and `computer_20250124` tool versions. To move an existing integration, see [Migrate from `computer_20251124`](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#migrate-from-computer-20251124). To move from `computer_20250124`, see [Move computer use to the toolset](https://platform.claude.com/docs/en/models/haiku-5-5/migration-guide#computer-use-toolset) in the Claude Haiku 5.5 migration guide.
37 - On Amazon Bedrock, Claude Opus 5.5, Claude Sonnet 5.5, and Claude Haiku 5.5 accept the earlier `computer_20251124` tool version as Claude Opus 5 and Claude Sonnet 5 do.
36 - Claude 5.5 and later models support computer use through the `computer_toolset_20260801` toolset. They return a 400 error for any computer use tool version they don't accept, such as `computer_20251124` on the Claude API. To move a `computer_20251124` integration to the toolset, see [Migrate from `computer_20251124`](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#migrate-from-computer-20251124).

3837 - Claude Opus 4.7, Claude Opus 4.6, Claude Sonnet 4.6, and Claude Opus 4.5 support computer use only through the earlier `computer_20251124` tool version, which requires a beta header; see [Earlier tool versions](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#earlier-tool-versions).

4948For tasks that stay inside webpages, the [browser use tool](https://platform.claude.com/docs/en/agents-and-tools/tool-use/browser-use-tool) is the closer fit: its member tools read and act on the page itself, and it doesn’t need a full desktop environment.

51<Note>
52 Computer use is available on the Claude API and [Claude Models on Google Cloud (Google managed)](https://platform.claude.com/docs/en/build-with-claude/claude-models-on-google-cloud/google-managed) as the `computer_toolset_20260801` toolset; see [API support](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#availability-feature-support) for the supported models.
50See [API support](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#availability-feature-support) for the models and platforms that support the toolset. [Earlier tool versions](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#earlier-tool-versions) lists each earlier version’s beta header and the models to use it with.

54 Existing `computer_20251124` integrations keep working on the models listed for it under [Earlier tool versions](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#earlier-tool-versions), and earlier tool versions remain available in beta for models and platforms that don’t support the toolset. See [Migrate from `computer_20251124`](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#migrate-from-computer-20251124) to upgrade, or [Earlier tool versions](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#earlier-tool-versions) for the beta headers.

21212116## Migrate from `computer_20251124`
21222117 
2123Upgrading from `computer_20251124` to the toolset is optional: the models listed for `computer_20251124` under [Earlier tool versions](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#earlier-tool-versions) keep accepting it with its beta header, so an existing integration keeps working until you change it. Claude 5.5 and later models are the exception on the Claude API and Claude Models on Google Cloud (Google managed): there they accept only the toolset. Upgrade an integration before you move it to one of them. On Amazon Bedrock, Claude Opus 5.5, Claude Sonnet 5.5, and Claude Haiku 5.5 accept `computer_20251124`. To upgrade, make the following changes together:
2118A `computer_20251124` integration works without changes on the models listed for that version under [Earlier tool versions](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#earlier-tool-versions). Upgrade the integration before you move it to a model that doesn’t accept `computer_20251124`, such as a Claude 5.5 model on the Claude API.
21242119 
2120To upgrade, make the following changes together:
2121 
212521221. **Remove the beta header.** Drop `anthropic-beta: computer-use-2025-11-24` from your requests. With the SDK, remove `betas` (csharp, go: `Betas`; java: `.addBeta()`) and call the Messages API through the standard client rather than the beta namespace.
212621232. **Change the `tools` entry.** Set `type` to `computer_toolset_20260801` and delete `name`, `display_width_px`, `display_height_px`, `display_number`, and `enable_zoom`. The toolset rejects each of these fields.
212721243. **Choose whether to keep zoom enabled.** Zoom is enabled by default on the toolset, whereas `enable_zoom` defaults to `false`. If your environment doesn’t implement zoom, add `"configs": {"zoom": {"enabled": false}}` to keep the previous behavior; otherwise implement it (see [Available actions](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#available-actions)).

21792176## Earlier tool versions
21802177 
2181Two earlier versions of the computer use tool remain available in beta for existing integrations, for models that don’t support the toolset, and on platforms where the toolset isn’t currently available. On Claude Platform on AWS, Amazon Bedrock, and Microsoft Foundry, computer use is available only through these earlier versions. Each requires its [beta header](https://platform.claude.com/docs/en/api/beta-headers) on every request, and their parameters are documented in the [beta Messages API reference](https://platform.claude.com/docs/en/api/beta/messages/create). With the SDK, pass the header through `betas` (csharp, go: `Betas`; java: `.addBeta()`) and use the beta namespace; only the computer use tool needs the header, not the bash or text editor tools in the same request.
