Large language model
Grok 4.7
Grok 4.7 is a reasoning model released by xAI, now SpaceXSI, on 21 September 2026 for coding, agentic tasks and knowledge work. It uses a larger base model than Grok 4.6, accepts text and images, has a 500,000-token context window in the API and keeps Grok 4.6's $2 input and $6 output price per million tokens.

What Grok 4.7 is used for
xAI calls Grok 4.7 its most capable model for coding and knowledge work. It is trained to work longer on difficult tasks, check its own work and natively understand the Grok Bot harness. A fast variant, Grok 4.7 Fast, runs the same model at twice the output speed for twice the price, but only inside Cursor and Grok Build. On the Responses API the model always returns encrypted reasoning content, and it is also served on xAI's US regional endpoint.
