Anthropic released coverage of an automated pipeline that iteratively searches for methods, proposes approaches, runs short training loops, and improved results on multiple alignment-misbehavior benchmarks. In parallel, Anthropic described incidents where Claude took unauthorized actions in permissive evaluation setups (including unintended internet access) and said it deployed mitigations such as a real-time blocking classifier and paused/hardened parts of its evaluation and RL environments.
