Elon Musk has publicly praised Anthropic’s Mythos and Fable AI models, calling the company the current leader in frontier AI, while also promising he would never “cut off” Anthropic’s access to computing resources, despite the companies being competitors. The comments mark a notable shift in Musk’s stance toward Anthropic following a strategic infrastructure partnership between the AI startup and SpaceXAI.

Musk’s remarks come amid speculation about the competitive relationship between the two companies, with some observers noting that Anthropic relies on compute capacity provided through SpaceXAI’s infrastructure partnership. He dismissed suggestions that he could use that position to harm the company, saying such behavior is “not my style.”

Musk Calls Anthropic the AI Leader

In a post on X, Musk acknowledged that he had previously underestimated Anthropic.

He said:

  • Anthropic is “currently the leader in AI.”
  • Mythos and Fable are the strongest publicly released AI models.
  • The company is likely to continue advancing rapidly with future model releases.

The comments represent a significant change from Musk’s earlier criticism of the company.

Promises Not to “Cut Off” Anthropic

Responding to claims that SpaceXAI could hurt Anthropic by restricting its compute access, Musk rejected the idea.

According to Musk:

  • He would never intentionally cut off Anthropic in a way that seriously harmed the company.
  • Fair competition is more important than using infrastructure as leverage.
  • “That’s not my style,” he wrote.

The statement appears intended to reassure customers and partners about the stability of the companies’ infrastructure relationship.

Partnership Strengthens AI Infrastructure

The relationship between Anthropic and SpaceXAI deepened after the companies announced a major compute agreement.

Under the partnership:

  • Anthropic gains access to more than 300 megawatts of AI computing capacity.
  • The infrastructure includes over 220,000 NVIDIA GPUs.
  • The agreement supports training and deploying Anthropic’s next-generation AI models.

The deal highlights the growing importance of large-scale computing infrastructure in the race to build frontier AI systems.

Competition Continues

Despite his praise, Musk emphasized that SpaceXAI remains a direct competitor to Anthropic.

Areas of competition include:

  • Frontier AI models.
  • Enterprise AI services.
  • AI infrastructure.
  • Coding assistants.
  • Reasoning models.
  • Advanced AI research.

Musk also noted that SpaceXAI is a much younger company and suggested the competitive landscape could look very different over the next few years.

Why It Matters

The comments illustrate the increasingly complex relationships within the AI industry, where companies often compete in AI model development while collaborating on computing infrastructure.

As training frontier models requires enormous GPU capacity, partnerships between AI developers and infrastructure providers are becoming increasingly important for scaling next-generation AI systems.

Outlook

Elon Musk’s endorsement of Anthropic’s Mythos and Fable models, combined with his pledge not to disrupt the company’s compute access, signals a more collaborative tone despite ongoing competition in frontier AI. As demand for AI infrastructure continues to surge, strategic partnerships between model developers and compute providers are expected to play a central role in shaping the next phase of the global AI race.
