I have one hour to burn through my Claude token limit. I’ve resorted to feeding it the Linux kernel. This is fine. Genuine question though — what repos are worth having AI actually dig into? Send help (or links). — 今天的 Claude token 用不完。 我：行吧，去把 Linux 内核全读一遍。 有哪些代码库值得 AI 认真啃？求推荐👇

Claude Sonnet 5.5 is out! We wrote a guide for building with it: • choosing between Sonnet 5.5 and Opus 5.5 • migrating from Sonnet 5 and tuning effort • using it in Claude Code

Claude can now help you build evaluations and hillclimb on them. In this article, we share guidance on eval design & skills that Claude Code can use to improve your applications.

Claude Sonnet 5.5 (max) makes large strides on Terminal-Bench, sitting among the top models for both Terminal-Bench 4.0 and Terminal-Bench-Science. In Terminal-Bench 4.0 it scores 64%, a 50 point increase over Claude Sonnet 5 (max), and slightly above 60% for Opus 5.5 and GPT-6 Astra (xhigh). On our leaderboard for Terminal-Bench-Science - a benchmark of agentic terminal use to complete realistic scientific research workflows across domains - it scores 53% and sits behind only GPT-6 Astra and Opus 5.5. Terminal-Bench-Science is not currently included in the Artificial Analysis Intelligence Index.
