Chain-of-thought reasoning: from Google research to closing AI transparency
Chain-of-thought prompting, formalized by Google researchers in 2022, pushed models to work through problems step by step and changed how AI systems tackle reasoning tasks. The technique is now built natively into OpenAI's models, but the visibility it once offered into a model's internal steps is narrowing. That shift raises concerns about how developers and regulators can audit increasingly capable systems.
