GPT 5.1
GPT-5.1 upgrades GPT-5 with two models, Instant and Thinking. Instant is warmer and more conversational, now with adaptive reasoning for harder prompts and better instruction following. Thinking adapts its thinking time per task and writes clearer, easier to understand answers. Rollout starts in ChatGPT, then API.
