US EditionOpenAI Launches ChatGPT 5.1 with 8 New Personalities, Warmer Tone, and Quicker Replies
OpenAI’s GPT-5.1 improves math and coding with two modes that allocate compute based on question difficulty and offers eight customizable personality presets.
- On November 12, 2025, OpenAI unveiled GPT-5.1, introducing two variants: GPT-5.1 Instant, described as `warmer, more intelligent, and better at following your instructions`, and GPT-5.1 Thinking, focused on tougher problems.
- Facing criticism that GPT-5 felt `colder`, OpenAI designed GPT-5.1 to restore connection and reports `significant improvements` in AIME 2025 and Codeforces performance.
- Users are initially routed automatically to the variant that best fits their prompt, with both GPT-5.1 Instant and GPT-5.1 Thinking assessing question difficulty and eight personality presets available.
- Early access begins this week for Pro, Plus, Go, and Business subscribers, followed by free users soon; both models join the API later this week, with Enterprise and Education plans previewing for one week and older GPT-5 versions accessible for three months.
- Walmart partnered with OpenAI to power conversational shopping via ChatGPT Instant Checkout, announced last month, while Adam Fry, product lead, posted a fix checklist for the macOS-only ChatGPT Atlas browser competing with Perplexity's Comet.
