Summary
OpenAI has released GPT-5.1, an upgrade to its flagship GPT-5 model, featuring two new versions: GPT-5.1 Instant and GPT-5.1 Thinking. The update makes ChatGPT smarter and more enjoyable to use, with GPT-5.1 Instant described as 'warmer, more intelligent, and better at following instructions,' while GPT-5.1 Thinking is 'easier to understand and faster on simple tasks, and more persistent on complex ones.' The system now includes eight personality options (Default, Professional, Friendly, Candid, Quirky, Efficient, Nerdy, and Cynical) that users can toggle between, and queries are auto-matched to the most suitable model.
