Article Summary
OpenAI has unveiled GPT-5.1, a significant update to its ChatGPT model, focusing on enhanced user experience through customizable personalities. The new model, available in two variants – GPT-5.1 Instant and GPT-5.1 Thinking – offers users a selection of eight distinct conversational tones: Default, Professional, Friendly, Candid, Quirky, Efficient, Nerdy, and Cynical. This allows users to tailor the model’s responses to their specific needs and preferences. The ‘Instant’ version is designed to be ‘warmer, more intelligent, and better at following your instructions,’ while the ‘Thinking’ version prioritizes ease of understanding and speed on simple tasks, with enhanced persistence on complex ones. OpenAI is rolling out these models incrementally, initially through ChatGPT and then via a legacy dropdown menu for existing GPT-5 users. Alongside these core updates, OpenAI is experimenting with direct style fine-tuning settings, and is leveraging its strategic partnership with Microsoft, evident in the increasing integration of Anthropic’s models into products like Copilot. This follows a somewhat underwhelming initial reception to GPT-5 in August, leading to a temporary return of GPT-4o.Key Points
