Elon Musk’s SpaceX introduced Grok 4.6 yesterday, ensuring that its AI model matched GPT-5.6 Sol on the Artificial Analysis Intelligence Index, a composite score of nine benchmarks, but performing at a significantly lower price.
This agent model, according to the company, has a particular focus on long-running agents: “It stays with complex tasks across many steps, whether researching a topic, analyzing information, working across a codebase, or turning an idea into a polished application or work artifact.”
Grok 4.6 was available yesterday in Cursor — recently acquired by SpaceX — and Grok Build. In addition, it’s available via the SpaceX AI API.
Its base API price remains $2 per million input tokens and $6 per million output tokens, the same rates SpaceXAI set for Grok 4.5.
The model documentation lists a 500,000-token context window, text and image inputs, structured outputs, reasoning, and function calling.
SpaceX acquired Cursor’s parent, Anysphere, for approximately $60 billion in stock.
Grok 4.7 is significantly better than 4.6 and should be ready in 3 to 4 weeks.
Initial training is complete and now we’re adding a massive amount of SpaceX company data in supplemental training. This will be something special.
