Anthropic is actively engaging with the Trump administration about its latest frontier AI model, Mythos, even as the company navigates an ongoing dispute with the Pentagon, co-founder Jack Clark revealed Monday at the Semafor World Economy Summit in Washington.
The conflict stems from a disagreement over safety guardrails governing military use of Anthropic's AI technology. The dispute escalated last month when the Department of Defense designated Anthropic a supply-chain risk, effectively banning the company and its contractors from Pentagon partnerships. Despite the friction, Clark emphasized that national security remains a top priority for the firm.
"We have a narrow contracting dispute, but I don't want that to get in the way of the fact that we care deeply about national security," Clark said. He confirmed that Anthropic is briefing government officials on Mythos and plans to maintain that transparency with future model releases as well.
Mythos, which Anthropic unveiled on April 7, is the company's most advanced model to date, built with enhanced capabilities for coding and agentic tasks — meaning it can operate with a significant degree of autonomy. While those features represent a major leap forward in AI development, cybersecurity experts have flagged serious concerns. The model's advanced coding ability reportedly gives it an unprecedented capacity to detect software vulnerabilities and generate potential exploits, raising alarms across sectors including banking and critical infrastructure.
The legal battle between Anthropic and the Pentagon continues to unfold. A federal appeals court in Washington, D.C. recently declined to block the military's blacklisting of Anthropic, siding with the Trump administration. However, a separate appeals court reached the opposite conclusion in a related legal challenge filed by the company, leaving the matter unresolved.
The full scope of Anthropic's government discussions, including which agencies are involved beyond the Pentagon, has not been publicly disclosed.
