SpaceX's owner says its own agent product will route work to rival companies' models, including Anthropic's Claude Opus 5.5 (~21M views in five hours). A Grok Bot team member then said the Bots themselves will run on Opus 5.5.

Summary

Posted Oct 7, 2026 at 06:46 UTC, tagging Grok Bot's official X account (@bot) and @SpaceX. Musk says SpaceX will use "the best back end model for any given task" for Grok Bot. He names Anthropic's Claude Opus 5.5, Midjourney (images) and Suno (music) plus "other leading APIs", and gives no details on access, pricing, opt-outs or data handling. He posted nothing further in the thread.

Within half an hour, Grok Bot team member @poteto (X bio "Grok @Bot at @SpaceXAI") quote-posted it as "Grok Bot is getting an upgrade!" (https://x.com/poteto/status/2107728968501903652). In replies she said the Bot "itself will run on a different model, opus 5.5 is rolling out right now" (https://x.com/poteto/status/2107733029879943391) and that "all bots will be powered by opus 5.5, and they can spawn cloud agents of whatever cursor models we have" (https://x.com/poteto/status/2107735424089424174, ~106K views). She also said model choice is "automatic!" (https://x.com/poteto/status/2107735520885584135).

Top replies under Musk's post asked for an opt-out from data going to Anthropic, whether GPT models were included and whether it costs extra. Covered on Oct 7 by RuntimeWire, dev.ua, TVC News and KuCoin/BlockBeats. No tier-1 outlet had covered it by ~11:40 UTC.

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.
