According to @OpenAI, the company has introduced a comprehensive framework and evaluation suite designed to measure chain-of-thought (CoT) monitorability in AI models. The system includes 13 distinct evaluations conducted across 24 diverse environments, enabling precise measurement of when and how models verbalize specific aspects of their internal reasoning processes. This development provides AI developers and enterprises with actionable tools to ensure more transparent, interpretable, and trustworthy AI outputs, directly impacting responsible AI deployment and regulatory compliance (source: OpenAI, openai.com/index/evaluating-chain-of-thought-monitorability).
