OpenAI深夜放出GPT-5狙击谷歌！基准测试碾压前代模型，价格比Claude更便宜

Core Viewpoint - OpenAI has officially launched the GPT-5 model, marking a significant step towards artificial general intelligence (AGI), although it does not yet possess all the characteristics required for AGI [3][6]. Model Features and Improvements - GPT-5 is claimed to be smarter, faster, more practical, and more accurate than its predecessors, with a lower hallucination rate [3][17]. - The model can recognize when it cannot complete a task and avoids guessing, providing clearer explanations of its limitations [4]. - It features a context window of 256,000 tokens, an increase from the previous 200,000 tokens, allowing for better understanding of long conversations and documents [10]. New Model Variants - OpenAI introduced two new versions: GPT-5-mini and GPT-5-nano, with the latter being faster and cheaper [6][9]. - Free users can access GPT-5 and GPT-5-mini, while Plus subscribers enjoy higher usage limits and access to more powerful versions [8]. Pricing Structure - The pricing for API usage is set at $125 per million input tokens and $10 per million output tokens for GPT-5, while GPT-5-mini and GPT-5-nano have lower rates [9][30]. - Pro users can connect their Google services to ChatGPT, enhancing functionality [9]. Performance Metrics - GPT-5 outperformed previous models in various programming benchmarks, achieving scores of 74.9% in SWE-Bench Verified and 88% in Aider Polyglot [11]. - It is noted as the best-performing model in health-related tasks, significantly surpassing earlier models in specific benchmarks [16]. User Engagement and Feedback - ChatGPT currently has nearly 700 million weekly active users and 5 million paid enterprise users [18]. - The launch of GPT-5 has generated significant discussion on social media, with various industry leaders expressing their views [20][21]. Industry Impact - Microsoft has integrated GPT-5 across its platforms, highlighting its advancements in reasoning, programming, and conversation [22]. - The model is seen as a breakthrough in understanding complex documents, according to industry executives [24].
