A new research paper published on arXiv explores the monitorability of Chain-of-Thought (CoT) reasoning in large language models. The study, utilizing information theory, demonstrates that while mutual information between CoT and output is necessary for monitorability, it is not sufficient. The paper identifies approximation errors like information gap and elicitation error as key factors that can undermine CoT monitors. Researchers propose a practical, label-free training objective based on mutual information to mitigate CoT obfuscation and reward hacking, showing its effectiveness across various environments. AI
