OpenAI WebSocket Mode for Responses API
Persistent connections for faster AI agents
WebSocket Mode for the Responses API allows developers to maintain a persistent connection with AI models instead of resending the full context on every agent interaction. By sending only incremental inputs, it significantly reduces overhead and improves efficiency in complex workflows. This approach can cut end to end latency by up to 40 percent when using heavy tool call processes, making AI agents, automations, and real time applications faster, more scalable, and more responsive.
