Grok Bot goes multi-model: Musk says it will pick the best AI for each task
On October 7, 2026, Elon Musk said Grok Bot will use the best back end model for each task, naming Claude Opus 5.5, Midjourney, and Suno. What he said, what is still unknown, and what home users should check.

If you use Grok Bot at home, the AI doing the work behind your Bot may soon come from more than one company. Early on October 7, 2026, Elon Musk posted on X that Grok Bot will use whichever back end model fits the task best, including models and services that SpaceXAI does not make.
This is a direction, not a new button in the app. There is nothing to install today. But it changes what you should assume about where your requests go, so it is worth five minutes.
What Musk posted
Here is the post on X, word for word:
Important note regarding Grok @Bot:
Elon Musk (@elonmusk), October 7, 2026
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.
The services he named:
- Claude Opus 5.5: Anthropic’s general purpose AI model
- Midjourney: an AI image generator
- Suno: an AI music generator
- “Other leading APIs”: not named
Coverage from RuntimeWire, City AM, and TechCity Authority reports the same wording. RuntimeWire puts it plainly: the post “describes a direction, not a technical launch.”
Quick background
SpaceXAI launched Grok Bot in beta in August as “always-on agents” that get their own cloud computer, sign in to your tools, and keep working after you step away. It comes with paid Cursor plans or a linked SuperGrok subscription.
On September 21, 2026, SpaceXAI released Grok 4.7 and said it trained that model “to natively understand the Grok Bot harness.” That is useful context for why this post surprised people. Musk’s post does not mention Grok 4.7 at all. It talks about picking the best tool for each job, from whichever company makes it.
If you want the longer history of xAI’s own models, see our Grok 4.5 launch note.
What is still unknown
The post is two sentences. It leaves the questions home users actually care about unanswered:
- Timing. Musk said “going forward” but gave no date for when outside models start handling tasks.
- Whether you can see the model. Nothing says the app will tell you which company handled a request, or let you choose. Grok Bot’s admin documentation currently says “Cursor manages model selection,” so the choice is not in your hands today.
- Costs. No word on whether outside models change pricing or use up your plan’s included usage faster.
- Your data. Sending a task to Claude, Midjourney, or Suno means that request goes to another company. The post does not say what gets shared, under which terms, or whether you can opt out.
RuntimeWire and TechCity Authority both flag these same gaps. Until SpaceXAI publishes details, treat them as open questions, not as answered either way.
What to do at home
None of this needs a panic setting change. It is a good moment for some basic hygiene, the same kind we suggested when third-party AI agents came to Google Home.
- Review what your Bots can reach. Open Grok Bot and look at the apps and accounts you have connected. Disconnect anything a Bot no longer needs. Fewer connections means less that could travel with a request.
- Keep approvals on. Grok Bot can ask before sensitive actions. SpaceXAI’s own security guidance suggests keeping sending, purchasing, and deleting behind approval, and choosing Allow once over Always allow for anything touching money or accounts.
- Never paste passwords into chat. When a Bot needs a login, use the app’s masked secret request or secure form instead.
- Check your privacy settings. Grok Bot follows your Cursor account data settings, including training opt-out. Make sure they say what you think they say.
- Watch the changelog. SpaceXAI posts Grok Bot changes on its public changelog. That is where a model picker, a new usage rule, or a data notice would show up first.
Do this / don’t do that
Do
- Read the actual post before trusting a headline about it.
- Assume a request you hand to a Bot could be processed by a company other than SpaceXAI once routing begins.
- Keep the sensitive stuff (banking, medical, family records) out of Bot tasks until SpaceXAI explains data handling.
- Check the changelog and your usage page over the next few weeks.
Don’t
- Do not assume every task already goes to Claude, Midjourney, or Suno. Musk did not give a start date or say which tasks go where.
- Do not assume Grok Bot is “Grok only” either. The stated plan is to use whatever works best.
- Do not turn on Always allow to save a few clicks while the details are still unclear.
Bottom line
On October 7, 2026, Elon Musk posted that Grok Bot will use “the best back end model for any given task,” naming Claude Opus 5.5, Midjourney, and Suno. That is a real shift for a product from an AI lab that also builds its own models, including Grok 4.7 in September. Timing, visibility, cost, and data handling are still unannounced. At home: trim what your Bots can reach, keep approvals on, check your privacy settings, and watch the changelog. That is the whole job for now.
