OpenAI has officially launched GPT-5.1, enhancing its chatbot capabilities just three months after GPT-5’s debut. This model update introduces two variants: GPT-5.1 Instant, which is designed for quick, warm, and intelligent interactions, and GPT-5.1 Thinking, focused on complex problem-solving and thoughtful reasoning. Users will initially be automatically directed to the variant that best suits their needs. Along with these models, OpenAI has added eight new personality presets—Default, Professional, Friendly, Candid, Quirky, Efficient, Nerdy, and Cynical—enabling users to tailor their interactions. The update aims to reduce robotic responses, offering a more personal touch. Paid subscribers will experience this rollout first, with free users gaining access soon. The enhancements promise improved instruction-following and faster responses, boosting efficiency for productivity-focused users. For optimal use, check your options, experiment with personality presets, and stay informed about updates from OpenAI.
