On September 22, 2026, Elon Musk's xAI officially released its new large-scale model, Grok 4.7, positioning it as the most powerful model for programming and knowledge work currently available. The model adopts a new foundational architecture with 2.1 trillion parameters and undergoes extended reinforcement learning training, significantly enhancing its ability to handle complex tasks. It excels particularly in long-duration execution, self-checking, and professional knowledge work. Official tests show that it outperforms its predecessor, Grok 4.6, by a significant margin in benchmarks such as CursorBench 4.0, DeepSWE v1.1, and Terminal Bench 4.0, even surpassing competitors like GPT-5.6 Sol in some tests. Grok 4.7 also strengthens its capabilities in long-context management and result verification, with optimizations for professional scenarios (e.g., legal, financial analysis), enabling it to handle some tasks typically performed by lawyers, nurses, and other professionals. In terms of safety, the model employs a new protection system, performing exceptionally well in biosafety and cybersecurity benchmark tests. Pricing remains the same as the previous generation, with API pricing set at $2 per million input tokens and $6 per million output tokens. A faster version, offering doubled output speed at double the price, is also available, providing a clear cost-performance advantage. Currently, Grok 4.7 is available through Cursor, Grok Build, and Grok API, supporting third-party programming tools and cloud services.
