Summary

Vercel's AI Gateway added WebSocket support for the OpenAI Responses API, letting clients hold a persistent connection and send only the new turn each time.

Key facts

AI Gateway now supports WebSocket mode for the OpenAI Responses API.
A persistent connection can stay open across turns.
Each turn is continued by sending only the new input.
The feature is live as of 2026-07-27.

Why it matters

Developers building on the Responses API can keep one connection open instead of reconnecting per turn, which may simplify streaming and multi-turn request handling.
