Musk outlines Grok Bot use of third-party AI models

SpaceX will select a backend model for each task, Elon Musk said, naming Claude Opus 5.5, Midjourney and Suno. The statement sets out an intended product approach for Grok Bot, but does not identify which tasks will use which model. No regulator, legal process or formal decision is identified in the report.

The development is a change in how Grok Bot may draw on AI models, according to Musk’s statement reported by TNW. The report does not describe a law, investigation, consultation or agreement governing the planned use. It also does not say that any authority has reviewed or approved the arrangement.

Grok Bot is an agent app

Grok Bot is described as an AI agent app from SpaceXAI, the AI business Musk folded into SpaceX. The app launched in August. Each Bot runs on its own computer and can carry out several tasks in parallel, according to the source.

The stated selection principle is to use the backend model most likely to provide the best outcome for a given task. That describes the intended routing choice in general terms, rather than a binding allocation of work among named models. The report gives no technical explanation of how the selection is made or measured.

Named providers receive no stated allocation

Musk’s announcement names Claude Opus 5.5, Midjourney and Suno, alongside other leading APIs. The source does not identify the tasks, data or circumstances associated with any one of them. It therefore leaves the practical scope of external model use open.

The report characterises Anthropic, Midjourney and Suno as building models for text, images and music. That description does not establish that Grok Bot will route text, image or music tasks to a particular named provider. No statements from those companies are included, and no response from them is reported.

Access problems have no official cause

The account says the plan followed reports of problems reaching Grok on mobile and web services a day earlier, as reported by City AM. SpaceXAI gave no official cause for those access problems. Musk did not say that the planned use of external models was a remedy or that the two developments were connected.

The report also describes other product and market context. Since late September, teams have been able to publish a shared Bot for colleagues to use in the app or Slack, according to the product changelog. The source offers no user totals or other figures to establish adoption, and describes no legal conditions for that feature.

Musk launched xAI in 2023 to compete with OpenAI and invested heavily in computing for Grok models, the report says. It also says Musk announced that SpaceXAI would take the name SpaceXSI. Neither point supplies further detail about oversight, data handling or the terms for external model access.

The unanswered issues include the tasks involved, the selection criteria and any contractual limits on model use. The report names no authority and gives no legal status for the plan. SpaceXAI has not provided an official cause for the separate access problems in the account. Further statements from SpaceXAI or the named providers would clarify implementation, while the present report records no such responses.
