GPT-5来了！免费用户也能用的“博士级”对话体验

Core Insights - OpenAI has launched GPT-5, which shows significant improvements in intelligence, speed, and accuracy, although it has not yet achieved Artificial General Intelligence (AGI) [1][2] - The release includes two new variants: GPT-5-mini and GPT-5-nano, catering to different user groups [2][3] - GPT-5 has demonstrated superior performance in programming and health-related tasks compared to previous models [5][6] Model Variants and Access - GPT-5-mini is lightweight, while GPT-5-nano is faster and cheaper, available only through API [2] - Free users will have access to GPT-5 and GPT-5-mini, while Plus subscribers ($20/month) will have increased usage limits [2] - Pro users ($200/month) will have unlimited access to GPT-5 and enhanced versions like GPT-5-pro and GPT-5-thinking [2][3] Performance Enhancements - GPT-5 outperformed previous models in various programming benchmarks, achieving scores such as 74.9% in SWE-Bench Verified and 88% in Aider Polyglot [5] - The model can handle complex tasks and provide clear instructions, making it an effective programming partner [5] - In health-related benchmarks, GPT-5-thinking showed significant improvements, although specific scores were noted [6] Reduction of Misinformation - The new model has significantly reduced the tendency to generate false information, with a 26% decrease in hallucination rates compared to GPT-4o and a 65% reduction for GPT-5-thinking [7] - OpenAI has implemented safety measures to ensure the model fails gracefully when unable to complete tasks [7] User Experience - The overall experience of using GPT-5 is reported to be very positive, especially for users who may not focus on the technical details of the model [8]
