Anthropic SDK v0.124.0 Moves Files and Skills APIs to General Availability, Adds Computer Use and Browser Use Toolsets

Anthropic shipped version 0.124.0 of its anthropic-sdk-python library, marking the Files and Skills APIs as generally available (GA) and adding new toolsets for computer use and browser use, according to the release notes published on GitHub.

The release, tagged by Anthropic's automated stainless-app publishing bot on August 19, 2026, is documented in commit 9a09e84 and is available now via the standard Python package channels. The full diff against the prior release is published at v0.123.0...v0.124.0 on GitHub.

What changed

Two items are called out in the changelog under "Features":

• Files and Skills APIs reach GA status. These APIs, which had previously been available in preview or beta form, are now considered stable for production use. Anthropic has not published specific details in this release about rate limits, pricing, or SLA guarantees tied to GA status beyond the changelog entry itself.
• New computer use and browser use toolsets. The SDK now exposes toolsets for computer use and browser use, extending the categories of tool-calling capability developers can invoke through the Python client. Anthropic has previously supported computer use as a capability in earlier developer previews; this release formalizes it as a toolset within the SDK's Files and Skills surface area.

No pricing changes, deprecations, or breaking changes are listed in the release notes.

Context

The Files API allows developers to upload and reference documents and other assets in conversations with Claude models without re-sending raw content on every request. The Skills API lets developers package reusable capabilities that Claude can invoke. Moving both to GA signals that Anthropic considers the underlying infrastructure stable enough for production workloads rather than experimental use.

Computer use — the ability for a model to control a computer interface by interpreting screenshots and issuing mouse/keyboard actions — has been a focus area for Anthropic since earlier Claude model releases. Packaging it as a toolset in the SDK, alongside a new browser use toolset, suggests Anthropic is consolidating agentic capabilities into a more structured, discoverable interface for developers building automation and agent products on Claude.

What this means

This is an SDK and API-surface update, not a new model release — no new Claude checkpoint, weights, or version is being introduced. Its practical effect is on developer workflows: teams building on the Files, Skills, computer use, or browser use APIs can now treat those interfaces as stable rather than subject to breaking changes typical of beta features. For teams already building agentic or document-heavy Claude applications, this reduces integration risk. For teams evaluating whether to adopt these APIs, GA status is typically the signal to move from prototypes to production deployment.
