Grok 4.7

Grok 4.7, SpaceXSI's frontier model for coding, agentic tasks, and knowledge work, is now available on the xAI API as grok-4.7. It has a 500k context window, text and image inputs with text-only output, and no text output limit. Pricing is $2 / $0.50 / $6 per 1M tokens (input / cached input / output) below 200k prompt tokens, and $4 / $1 / $12 above. Reasoning effort supports low, medium, high (default), and xhigh. On the Responses API, grok-4.7 always returns reasoning.encrypted_content, even when include does not list it. It is also served on the US regional endpoint. Grok 4.7 Fast is the same model and costs 2x the standard token rates, or 1.5x for long-context requests. It's available only in Cursor and Grok Build, not on the public xAI API, and is billed through your plan there. See the Grok 4.7 overview and the announcement.
