Elon Musk says Grok Bot will route tasks to outside models like Claude Opus 5.5
Important note regarding Grok @Bot: Going forward, @SpaceX will use the best back end model for any given task, including Claude Opus 5.5, MidJourney, Suno and other leading APIs. Whatever is most likely to give you the best outcome.
Context
Grok Bot users would get whichever model fits the task best, including models from rival labs.
Grok Bot is the always-on agent product from SpaceXAI, the renamed xAI. Musk later added that simple questions will go to small, fast models and complex ones to large models. TestingCatalog noted the move could raise questions about expectations for future Grok models.
Deep dive
In an X post on October 7, Elon Musk said SpaceX will use the best back-end model for any given task in Grok Bot, naming Anthropic's Claude Opus 5.5, Midjourney and Suno. Those cover text and reasoning, images and music. Later that day he said most Bot requests are simple and will be handled by a fast version of Grok 4.8 once it comes out.
Grok Bot is SpaceXAI's agent app, in which each Bot works on its own cloud computer. A member of the Grok Bot team said on X that all Bots will run on Claude Opus 5.5 and can start cloud agents that use Cursor models.
The change turns Grok Bot from a showcase for in-house Grok models into a router across rival models, with SpaceXAI deciding which model handles which task.
What to expect next
Musk said the fast Grok 4.8 that will handle most simple requests is coming but gave no date. No rollout schedule, routing rules or pricing for the outside models have been published, and SpaceXAI has not said whether users will see or choose which model handled a task.
Data handling is an open question. Routing tasks to Anthropic, Midjourney or Suno means user content reaches those companies, and SpaceXAI had not published terms for that at the time of these posts.
