Anthropic published a 78.2% SWE-bench Verified score for Opus 4.8 with a minimal scaffold, a 1.4-point jump over the previous top entry. Lab-reported; the leaderboard maintainers have queued an independent run.
Anthropic moved the computer use tool out of beta as computer_toolset_20260801 (no beta header, batch actions in one turn, zoom on by default, per-member configs) and launched a new browser use tool (browser_toolset_20260801) that drives a browser via its accessibility tree, elements, forms, and tabs rather than screenshot-and-click, adding element references, form input, tab management, download reporting, and opt-in file upload. Both toolsets are available for Claude Fable 5, Mythos 5, Opus 5, Sonnet 5, and Opus 4.8.
Anthropic's API changelog announced batch processing over the full 1M-token context window at a 70% discount, plus prompt-caching improvements. Materially changes the economics of long-document extraction workloads.
