Grok is xAI's language model family. As of October 2026 the recommended API model for code and chat is Grok 4.7 (grok-4.7), released September 21, 2026, with a 500K token context window, text and image input, a May 2026 knowledge cutoff, and reasoning effort from low up to xhigh. It costs $2 per million input tokens and $6 per million output tokens below 200K prompt tokens, and $4 and $12 above that. The API works with the OpenAI SDK by pointing it at api.x.ai, making it a drop-in replacement in existing codebases, and a per-model alias can track new versions automatically. Grok 4.7 Fast, at 2x standard token rates, is available only inside Cursor and Grok Build, billed through your plan there. Older models such as grok-4.6, grok-4.5, grok-4.3 and grok-4.20 remain listed if you need to pin a version.
