刚刚，GPT-5.1发布，OpenAI开始拼情商

Core Insights - OpenAI has launched significant updates to the GPT-5 series, introducing GPT-5.1 Instant and GPT-5.1 Thinking models, which enhance both intelligence and communication style [1][11]. Model Features - GPT-5.1 Instant: This model is designed to be more user-friendly, providing responses that are both warm and intelligent, with improved instruction-following capabilities [1][2]. - GPT-5.1 Thinking: This advanced reasoning model is optimized for efficiency, allowing it to allocate more time to complex problems while responding quickly to simpler queries [6][10]. Performance Improvements - The new models exhibit significant enhancements in areas such as mathematics and programming assessments, as evidenced by improved performance in tests like AIME 2025 and Codeforces [4]. - GPT-5.1 Instant can utilize adaptive reasoning, allowing it to determine when to take time for deeper thought, resulting in more comprehensive and accurate answers [3][10]. User Experience - The responses from GPT-5.1 Thinking are clearer and use less technical jargon, making it easier for users to understand complex concepts [10]. - The default tone of GPT-5.1 Thinking is warmer and more empathetic, contributing to a more pleasant user interaction [10]. Availability - The rollout of GPT-5.1 Instant and GPT-5.1 Thinking will begin with paid users, followed by free users and those not logged in, with a transition period for users to adapt to the new models [11][14]. - Both models will be available in the API, with GPT-5.1 Instant and GPT-5.1 Thinking being integrated into the existing system for a smooth transition [14]. Naming Convention - The update is labeled as GPT-5.1 to signify meaningful improvements while still being part of the GPT-5 series, with future iterations expected to follow a similar naming pattern [15].
