The entry says the model has a 500k context window, accepts text and image inputs with text-only output, supports low, medium, high (default), and xhigh reasoning effort, and is also served on the US regional endpoint. It adds that Grok 4.7 Fast, the same model, is available only in Cursor and Grok Build, not on the public xAI API. Grok 4.7 follows Grok 4.6, which the release notes list on August 12. These are hosted models; no release of weights is described. USASI has not tested Grok 4.7. https://unitedstatesofamericasuperintelligence.com/news/xai-releases-grok-4-5/ https://unitedstatesofamericasuperintelligence.com/news/xai-releases-grok-4-5/ Tue, 13 Oct 2026 12:00:00 GMT release xAI's API release notes record that on July 8, 2026 Grok 4.5, described as a model for coding, agentic tasks, and knowledge work, became available on the xAI API with configurable reasoning effort (low, medium, or high, with high as the default).
