Elon Musk says SpaceX‘s AI agent, Grok Bot, will use models from AI music platform Suno.
Musk named Suno alongside Anthropic‘s Claude Opus 5.5 and image generator Midjourney in a post on X on Wednesday (October 7).
Grok Bot, which launched in beta in August, is an AI agent app developed by SpaceXAI.
SpaceXAI is the AI company Musk founded in 2023 as xAI, which SpaceX acquired in February and renamed in July. Musk said on October 4 that it will be renamed again, as SpaceXSI, but gave no date for the change.
Musk wrote: “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.”
The post did not specify which tasks Grok Bot would route to which model, or when the change would take effect. In a follow-up post, Musk said simple questions would be routed to small, fast models and complex ones to large models.
For Claude, the change appears to be underway: a member of the Grok Bot team said on X that Opus 5.5 was rolling out and would power all Bots on the app. SpaceXAI has not said when music tasks will be routed to Suno.
Nor did Musk say how SpaceX would access Suno‘s technology.
Suno does not currently offer an official public API. MBW reported in July that the company was exploring the launch of one.
The company’s Chief Product Officer, Jack Brody, revealed those plans in a LinkedIn post on July 1, with a form for developers to express interest.
“Ahead of our partner powered model, we’re exploring a developer API and want to hear from you before we start building,” Brody wrote. “We plan to start with a curated group of partners so we can develop this thoughtfully, and we’re especially interested in applications that unlock experiences generative music makes possible for the first time.”
Suno did not give a timeline for the API’s launch at the time.
Suno co-founder and CEO Mikey Shulman said on October 1 that the company has moved past the paid subscriber and revenue figures it disclosed in February.
“The last stats that we released were 2 million subscribers, $300 million in revenue. We are far beyond that by now,” Shulman said, speaking at Bloomberg‘s Screentime conference in Los Angeles.
In June, Suno raised over USD $400 million in a Series D round at a USD $5.4 billion post-money valuation.
Suno settled Warner Music Group‘s copyright lawsuit against it in November 2025 and struck a licensing deal with the major.
It has since signed licensing deals with BMG and Believe, and launched its v6 suite of models, developed with all three partners, on September 9.
Suno retired its earlier models on the same day.
Universal Music Group and Sony Music Entertainment, neither of which has licensed Suno, filed a second copyright lawsuit against the company in Boston federal court on September 18.
The complaint accuses Suno of copying 60,202 of the labels’ recordings without a license and alleges that v6 was developed using outputs of Suno’s earlier models, which were trained on those recordings.
“Training a ‘new’ model on the outputs of an infringing model does not eliminate the infringement; it launders it,” the Universal and Sony complaint states. “…v6 is not a fresh start; it is the fruit of the same poisoned tree.”
“These claims remain fundamentally flawed on both the facts and the law,” Suno said in a statement.
Anthropic, whose Claude Opus 5.5 model was named first in Musk’s post, also faces music copyright litigation.
Independent music company Round Hill Music sued both Anthropic and Suno for copyright infringement on August 17 in the US District Court for the Northern District of California.
Each complaint seeks statutory damages of up to USD $150,000 per work willfully infringed, with Round Hill saying the total in each case could “potentially approach or conceivably exceed $1 billion.”
Anthropic was already defending three music copyright cases in the same district.
Concord Music Group, Universal Music Publishing Group, and ABKCO first sued Anthropic in Nashville in October 2023, in a case later transferred to California.
The same publishers filed a second suit in January 2026 over more than 20,000 songs, seeking over USD $3 billion.
BMG Rights Management brought a third case in March 2026 over 493 compositions.
Sony Music Publishing and Warner Chappell Music sued Anthropic in the same court on August 28, 11 days after Round Hill, meaning the publishing arms of all three majors are now litigating against the company.
SpaceX and Anthropic have an existing commercial relationship.
In May, Anthropic signed a deal to use the entire compute capacity of SpaceX’s Colossus 1 data center in Memphis, Tennessee, and later expanded the partnership to include capacity at Colossus 2.Music Business Worldwide
