Grok Bot nows pick best AI model per query: Musk

SpaceX upgraded Grok Bot to select the optimal AI model—Claude Opus 5.5, MidJourney, or Suno—based on user queries. Announced by Elon Musk on October 7, following Grok 4.7's launch, the bot now uses smaller models for simple questions and larger ones for complex tasks. SpaceX is also exploring server rentals to train third-party AIs.
