What Is the Responses API?
The Responses API (/v1/responses) is OpenAI's unified interface for building agentic applications, launched in March 2025. It fundamentally changes how you interact with OpenAI models by providing stateful conversations and a structured loop for reasoning and acting.
Key Innovation: Preserved Reasoning State
Unlike Chat Completions where reasoning is discarded between turns, Responses keeps the notebook open. The model's step-by-step thought processes survive into the next turn, improving performance by approximately 5% on TAUBench and enabling better multi-turn interactions.
