💎 Training on chain-of-thought may incentivize models to hide misaligned reasoning, undermining safety monitoring reliability.

The Gemini 4 Safety report states that components of its RL training procedure observe chain-of-thought (CoT) as context to up-weight reasoning, a mechanism the authors interpret as using auxiliary rewards or LLM judges to score partial CoT. The authors express concern that this process would incentivize models to suppress misaligned verbalizations and reduce CoT faithfulness, while noting that the cited Kaufmann et al. (2026) paper argues training on CoT is low-risk under specific conditions.
