What they do
This provider appears in the source directory as 'SpaceXAI' and serves the Grok model family — historically developed by Elon Musk's xAI, which merged with X Corp in 2025. Grok models (Grok 3/4/4.x) emphasize reasoning, real-time X/Twitter data access, and an irreverent persona. Treat the 'SpaceXAI' branding as reported-by-source; the verified lineage is xAI.
