Key Points

1CoT-Control: Open-source eval >13k tasks
2Controllability 0.1-15.4%, monitoring viable
3Better in larger models, worse in long reasoning

OpenAI launched CoT-Control eval suite across 13+ benchmarks testing 13 models' ability to obscure reasoning chains. Larger models show better controllability, but long reasoning reduces it, making CoT monitoring reliable for safety. Businesses can trust it for agent oversight.
