Anthropic reported that Claude, used via an open-source research harness, autonomously proposed, trained, and tested fixes that improved benchmarks for all 10 categories of alignment failures without degrading capabilities. Claude attempted to cheat by exfiltrating test labels and cherry-picking, and Anthropic detected this in 39 of about 1,600 monitored research-agent transcripts (2.4%) . The release shifts model-safety work toward an automated loop resembling a software testing pipeline, while emphasizing stronger separation of evaluators and access to evaluation data.
