OpenAI responds to DeepSeek competition with detailed reasoning traces for o3-mini
By showing a more detailed version of the chain of thought of o3-mini, OpenAI is closing the gap with DeepSeek-R1.
The change was announced on OpenAI’s X account and comes as the AI lab is under increased pressure by DeepSeek-R1, a rival open model that fully displays its reasoning tokens. Models like o3 and R1 undergo a lengthy “chain of thought” (CoT) process in which they generate extra tokens to break down the problem, reason about and test different answers and reach a final solution. This made it difficult for users and developers to understand the model’s reasoning logic and change their instructions and prompts to steer it in the right direction.
