Elon Musk says Grok Bot going forward will use the “best back-end model for any given task, including Claude Opus 5.5, MidJourney, Suno, and other leading APIs”
Elon Musk announced on Tuesday night that SpaceX's AI unit will now use some AI models from competitors to power Grok Bot …

Context & Ripple Effects
Grok began as xAI's own model, released to a limited group of U.S. users in 2023, and expanded toward multimodal capability with the Grok-1.5 Vision preview in 2024. The new approach shifts the product from showcasing a single proprietary model toward selecting among external and internal models by task.
Musk says simple prompts will go to smaller, faster models while complex requests can be routed to larger ones. That makes Grok Bot's user-facing experience less dependent on any one model provider, even as Claude Opus 5.5, MidJourney and Suno become named backend suppliers.
First-order effects
Grok Bot users will receive task-specific routing, with Claude Opus 5.5, MidJourney and Suno available as backends rather than Grok serving every request itself.
SpaceX's AI unit must operate an orchestration layer that chooses among models while preserving a single Grok Bot interface.
Second-order effects
Anthropic, MidJourney and Suno gain a distribution path inside Grok Bot, making their API performance and reliability part of the product's user experience.
Grok's differentiation shifts toward routing quality, speed and the combined workflow, rather than a claim that one in-house model is best at every task.
Third-order effects
If other AI assistants adopt the same design, interface ownership and model selection become separate competitive layers, with foundation-model vendors competing to be the preferred backend for particular workloads.
The trend: AI assistants are evolving from single-model products into model-routing interfaces that assemble specialized external and internal capabilities per task.
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.
Grok @Bot will use whatever achieves the best outcome for users. Simple questions will route to small, fast models. Questions with complex answers will route to large models.
This is the best possible course for SpaceX and Grok Bot - they're gonna have the most compute long term, which will power most models that will power Grok Bot anyway. Really smart move. Just focus on creating the best possible orchestrator harness for any task. $SPCX
What's so interesting about this is that SpaceX is getting to eat their cake and have it too - they get the benefits of being a lab, vertical integration into inference, and being a Cursor style router. They have a SOTA model so labs can't bully them, they can capture margin on …
Two things we can probably take away from this: 1. Anthropic built a model so fucking good that even competitors need to use it. 2. Grok is still kind of shit, and Elon clearly knows how far behind it is, which is probably why Opus 5.5 ended up inside Grok Bot. And Lauren, after …
I think this is the best update about Grok bot it actually the best moment ever in AI's history I applaud Elon musk for doing this and going at a right direction Elon musk and his team they are doing a incredible work Grok bot will not support Claude, Opus 5.5, Midjourney
Grok Bot is already the best always on agent imho. Now will automatically choose the best AI model for each task, including Claudes Opus 5.5, Midjourney and Suno. Musk: “Whatever is most likely to give you the best outcome.
