xAI's developer documentation now uses the name SpaceXSI

As of October 11, 2026, xAI's developer documentation at docs.x.ai is titled "SpaceXSI Docs", describes itself as the official SpaceXSI API documentation, and opens with "Get started with SpaceX Super Intelligence". The page's structured data still names the organization xAI and lists "SpaceXAI Docs" among the site's alternate names, and the company's Greenhouse job board still carried the name SpaceXAI the same day. xAI has been a wholly owned subsidiary of SpaceX since February 2026. USASI has not found an official announcement of the new name, and no change to the company's legal name has been documented; the catalog record now reads "xAI (SpaceXSI)".123
