OpenAI has introduced the GPT-5.1 family of AI models for its ChatGPT service, enhancing its capabilities. The GPT-5.1 Instant model provides faster, more natural responses, making it ideal for simple tasks while still capable of handling complex queries with adaptive reasoning. The GPT-5.1 Thinking model, focused on advanced reasoning, adjusts computational power based on query complexity, delivering quicker results for straightforward tasks and more detailed responses for difficult ones.
These models are rolling out to OpenAI’s paid users, including Pro, Plus, Go, and Business clients, with plans to extend access to free and guest users later. The new update also allows customization of ChatGPT’s conversational style, offering options like Professional, Candid, and Quirky. Legacy GPT-5.0 models will remain available for paid users for three more months. This follows OpenAI’s recent release of ChatGPT Atlas, a browser tool that enhances web browsing with AI-assisted features.
