Key Points

1Caches state to minimize API overhead.
2Up to 4K tokens/sec with GPT-5.3-Codex-Spark.
3Keeps familiar API with previous_response_id.
439% faster in alpha tests.

OpenAI introduced persistent WebSocket connections in Responses API, caching conversation state to cut redundant processing in tool calls. Agent workflows speed up by up to 40%, letting devs build faster apps. Proven in alpha with Vercel and Cursor.
