Previewing Ultrafast mode: GPT-5.6 Sol at up to 14X the speed
This is an API-only preview, so it mainly matters if your business builds tools on OpenAI's API for time-sensitive tasks like live customer support or fast financial lookups — it promises much faster responses from OpenAI's top model, but access is currently limited to select companies, so most everyday ChatGPT users won't see a change yet.
What changed
