According to OpenAI, monitoring a model’s chain-of-thought (CoT) is significantly more effective for identifying issues than solely analyzing its actions or final outputs (source: OpenAI Twitter, Dec 18, 2025). By evaluating the step-by-step reasoning process, organizations can more easily detect logical errors, biases, or vulnerabilities within AI models. Longer and more detailed CoTs provide transparency and accountability, which are crucial for deploying AI in high-stakes business settings such as finance, healthcare, and automated decision-making. This approach offers tangible business opportunities for developing advanced AI monitoring tools and auditing solutions that focus on CoT analysis, enabling enterprises to ensure model robustness, regulatory compliance, and improved trust with end users.
