SpaceXAI, the company behind the Grok models, has officially released Grok 4.6. The update zeros in on long-running agents, more complex interactions, and vision-heavy tasks — and it's priced to make rivals wince: output tokens cost one-fifth as much as GPT-5.6 Sol.
The model is already live in Grok Build, Cursor, and the API, with integrations for OpenRouter, Vercel, and Cloudflare. To celebrate launch week, Cursor and Grok Build are both offering double usage.
As for performance, Grok 4.6 has reached the front tier. It's posting a strong score on the Artificial Analysis Intelligence Index.
