Replace HTTP round-trips with persistent WebSocket connections; send only new input plus previous_response_id to cut context re-transmission overhead.
Summary
Multi-turn agentic workflows with 20+ tool calls see ~40% faster end-to-end execution. Reduces bandwidth and latency for stateful AI interactions, critical for real-time agent loops.

Implementation verdict
Replaces sequential HTTP calls with stateful WebSocket frames. Requires routing to wss://ai-gateway.vercel.sh/v1/responses and Bearer auth. Ready now—live on AI Gateway with store=false and ZDR compatible. Worth adopting if you're building multi-turn agents with frequent tool calls.
