How OpenAI’s Responses API WebSocket Revamp Accelerates Agent Workflows by 40%

OpenAI identified API‑overhead as the new bottleneck after faster model inference and introduced a persistent WebSocket connection that caches conversation state, overlaps request phases, and preserves the original API shape, delivering up to a 40% end‑to‑end latency reduction and dramatically higher TPS.

How OpenAI’s WebSocket Mode Accelerates Tool-Intensive Responses API Workflows

OpenAI’s new WebSocket mode for the Responses API keeps a persistent connection, sending only incremental inputs and previous response IDs, which cuts overhead and can boost end‑to‑end speed by 20‑40% for workflows that involve many tool calls.
