Elon Musk says Grok Bot will use the "best back end model for any given task, including Claude Opus 5.5, MidJourney, Suno" (Grace Kay/The Information)

Elon Musk has announced that his Grok Bot will use the "best back-end model for any given task". This includes Anthropic's Claude Opus 5.5, according to The Information, as well as image generator MidJourney and AI music platform Suno.

The move marks a shift away from relying exclusively on its own technology, with Grok now able to route work to outside models it judges best suited to a particular request.

Musk launched xAI in 2023 as a direct challenger to OpenAI and Anthropic, and has poured billions of dollars into building Grok. City AM reports that this decision also gives Anthropic another commercial boost as the AI company takes an increasingly large share of business spending.
