Browser Use now grades every run, and screenshot-heavy runs cost half as much
15 hours ago
Browser Use now grades every run with your own model, and notes what a site rejected or blocked even when the run succeeded. Screenshot-heavy runs cost about half as much, and the CLI starts its own Chromium when it can't use your Chrome. Also fixed: dead CDP addresses, slow cancels of cloud runs, and setup errors that a newer release would solve. Covers Browser Use 1.0.3, 1.0.4 and 1.0.5. Release notes 1.0.3: https://github.com/browser-use/browser-use/releases/tag/1.0.3 Release notes 1.0.4: https://github.com/browser-use/browser-use/releases/tag/1.0.4 Release notes 1.0.5: https://github.com/browser-use/browser-use/releases/tag/1.0.5 Full changelog: https://github.com/browser-use/browser-use/compare/1.0.2...1.0.5

Browser Use now grades every run. When the agent finishes, your own model makes one more quick request, checks the run against the task, and reports whether it worked, and if not, why.
The judge also notes what a site rejected, blocked or rate-limited, even when the run succeeded. Where a site pushed back, it now catches that every time, up from fewer than half. It checks screenshots too.
Screenshot-heavy runs now cost about half as much. Dropping one old screenshot per step broke the provider's prompt cache. Now they go in one batch past twenty, and the agent scores the same.
The command line now brings its own browser, like MCP. With no display, or remote debugging off, it starts Chromium and keeps it across calls until you reload. Named sessions get their own.
Three more fixes. A CDP address with nothing behind it fails in three seconds, not thirty. A cancelled cloud run frees the browser within ten seconds. And setup errors now say when upgrading would help.
Once you upgrade, the judge runs on every task. Its tokens count toward your bill. The release notes on GitHub show how to give it your own criteria, or switch it off.
