Speeding up agentic workflows with WebSockets in the Responses API
Justy and Cody dig into OpenAI’s writeup on speeding up agentic workflows with WebSockets in the Responses API. Cody is skeptical of the hype around raw model speed, while Justy keeps pulling it back to user pain: long, repetitive agent loops that make coding tools feel sluggish. They land on a practical read — the transport change matters most when the model is fast enough that API overhead becomes the bottleneck — and they sketch a weekend experiment for building a tiny stateful agent loop.
