Grok model updates, safety identifier, and new documentation

The release notes document changes and additions to the SpaceXSI platform's offerings. The most significant change is a company name alteration from 'SpaceXAI' to 'SpaceXSI' across various descriptions. New entries detail the availability of Grok 4.7, Grok 4.6, and Grok 4.5 models on the xAI API, specifying their context windows, input/output capabilities, and pricing structures. Grok 4.7 and 4.6 feature a 500k context window, text and image inputs with text-only output, and no text output limit, priced at $2/$0.50/$6 per 1M tokens (input/cached input/output) below 200k prompt tokens, and $4/$1/$12 above. Grok 4.5 has simpler pricing at $2/1M input tokens and $6/1M output tokens. Reasoning effort settings are available for all three. A 'Grok 4.7 Fast' variant is mentioned but is exclusive to Cursor and Grok Build, not the public API. Additionally, a 'safety_identifier' feature, allowing applications to pass an end-user identifier for policy violation attribution, is now listed under the new company name. A new 'Image Prompting Guide' and integrations with Replit and LangChain are also noted. The last updated date moved from October 9, 2026, to October 10, 2026. What specific changes were made to existing models or their capabilities beyond the naming convention is not detailed in the provided text.
