WebSocket support for OpenAI Responses API live on AI Gateway

UpdateVerifiedAdded Sep 22, 2026

AI Gateway now supports WebSocket mode for the OpenAI Responses API. You can keep a persistent connection open and continue each turn by sending only new input items plus previous_response_id , instead of re-sending the full context over a fresh HTTP request every turn.
