马斯克编程模型限时免费，反应速度快，叫板GPT-5

Core Insights - Elon Musk's AI company xAI has launched a new programming model called Grok Code Fast 1, which is designed for efficient coding and quick responses at a competitive price point [1][3]. Pricing and Performance - Grok Code Fast 1 offers a context window length of 256K and features a pricing structure of $0.20 per million input tokens, $1.50 per million output tokens, and $0.02 per hundred million cached input tokens [3]. - The model's performance is reported to be comparable to leading models like GPT-5 and Gemini 2.5 Pro, but at a significantly lower cost, making it an attractive option for users [3][10]. Technical Capabilities - Grok Code Fast 1 excels in programming languages such as TypeScript, Python, Java, Rust, C++, and Go, and can perform various programming tasks with minimal supervision [3][6]. - The model has achieved a score of 70.8% in the SWE-Bench-Verified complete subset tests, indicating strong performance in real-world programming tasks [6]. User Experience - Users can rapidly develop prototypes, such as a battle simulator, within a day using Grok Code Fast 1, showcasing its efficiency in iterative design and control [4][7]. - The model is currently available for a limited-time free trial of seven days and can be integrated with platforms like GitHub Copilot and Cursor [10].
