SpaceXAI has unveiled Grok 4.6, an artificial intelligence model that matches the capabilities of GPT-5.6 Sol on the Artificial Analysis Intelligence Index. The new version is priced at $2 for every million input tokens and $6 for every million output tokens. Grok 4.6 builds upon the previous 4.5 model, focusing on long-running agents and complex interactive and visual tasks.
It excels at handling intricate, multi-step tasks, such as research, analysis, coding, and application development. In tests, Grok 4.6 demonstrated strong performance in several agentic coding and knowledge work benchmarks, matching the performance of GPT-5.6 Sol. This new model is currently available in Cursor and Grok Build, with a fast variant available at double the price.
SpaceXAI has also enhanced Grok 4.6's safeguards to ensure the model remains useful and secure in various domains, including vulnerability patching, engineering design, and AI research. The company is offering two weeks of free usage to encourage users to explore the new model's capabilities.
