The new AI model is available via Grok Build, Cursor, and API for developers specializing in coding and knowledge work. SpaceXAI's latest release scored 19.6% on the Harvey Legal Agent Benchmark, outperforming GPT-5.6 Sol Max at 2.5% and Fable 5.1 Max at 6.7%. The model also reached 38.0% on Terminal-Bench 4.0 compared to 20.3% for Grok 4.6, while headline pricing remains at $2 per 1 million input tokens and $6 per 1 million output tokens.

Early user reports indicate pricing volatility and restrictive usage limits on the $300 per month supergrok heavy plan. Costs double for tasks exceeding 200,000 tokens or when utilizing a high-speed mode, according to some users. Elon Musk recommended utilizing the company's Build harness to achieve optimal results with the model's updated reasoning and self-verification capabilities.
