Anthropic moved five platform capabilities out of beta on the same day, and two of them are ours. Claude Computer Use is now generally available as the computer_toolset_20260801 toolset, with no beta header, batched actions — several in one turn — and zoom enabled by default.
The more interesting half is the new one. Claude Browser Use (browser_toolset_20260801) is a browser-only toolset that reads the page rather than a picture of it: read_page returns the accessibility tree with element references the model can act on by name, so a click targets an element rather than a coordinate that a layout shift can invalidate. It adds form input, tab management and download reporting on top.
Both toolsets run against a browser or desktop your own application hosts; nothing runs on Anthropic's side. Existing integrations pinned to computer_20251124 keep working but still need the beta header, and the request shape changed enough that Anthropic published a migration note.
Note the asymmetry in platform coverage. Computer use is documented on the Claude API, Claude Platform on AWS (beta), Amazon Bedrock (beta), Google Cloud and Microsoft Foundry (beta) — but platforms other than the Claude API and Google Cloud still offer only the earlier beta tool versions. Browser use is Claude API only.
