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.

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.

Build agentic AI applications with OpenAI's Responses API - the stateful successor to Chat Completions. Preserves reasoning across turns for 5% better multi-turn performance and 40-80% improved cache utilization. Use when: building AI agents with persistent reasoning, integrating MCP servers for external tools, using built-in Code Interpreter/File Search/Web Search, managing stateful conversations, implementing background processing for long tasks, or migrating from Chat Completions to gain polymorphic outputs and server-side tools.
