I’m experiencing an issue with the o3 model when using the new responses endpoint. Even though I explicitly request detailed reasoning summaries with the following configuration: "reasoning": { "effort": "medium", "summary": "detailed" } In most cases (more than 90% of the time), the model do…

O3 model in API often omits reasoning summary despite reasoning.summary: detailed
