xAI launches Grok 4.7 for coding and knowledge work

Confirmed
On Monday, Sept. 21, 2026, xAI published Introducing Grok 4.7. The company calls it its most powerful model for coding and knowledge work — a new, larger base than Grok 4.6, trained with a longer reinforcement-learning run on harder multi-hour tasks, with stronger self-checking and longer-context handling. xAI says it is served at the same price and speed as Grok 4.6, starting at $2 per million input tokens and $6 per million output tokens, with a fast variant at twice the output speed and twice the price. The post puts Grok 4.7 at 46.3% on CursorBench 4.0 (xHigh) and says availability starts in Cursor, Grok Build, the Grok API, third-party coding harnesses, and cloud routers. xAI also describes a new safeguard stack and a 62.4% score on LatchBio’s biosafety benchmark. No separate system-card PDF was linked on the launch page the desk fetched.
