Anthropic has opened lines of communication with the Trump administration concerning its latest frontier artificial intelligence model, Mythos, the companys co-founder Jack Clark said on Monday. Clark made the remarks at the Semafor World Economy event in Washington, indicating the company is engaging government officials about its current and future models.
These talks come after a recent rupture with the U.S. Department of Defense. The Pentagon terminated business with Anthropic last month following a contract dispute between the two parties. In March the Pentagon had designated Anthropic a supply-chain risk, barring the agency and its contractors from using the company's services.
The underlying disagreement that prompted the Pentagon's action centered on the terms and guardrails for military uses of Anthropic's AI systems. Clark characterized the matter as a "narrow contracting dispute," while emphasizing the companys stated interest in national security and in ensuring government awareness of emerging models.
"We have a narrow contracting dispute, but I dont want that to get in the way of the fact that we care deeply about national security," Clark said. "Our position is the government has to know about this stuff ... So absolutely, were talking to them about Mythos, and well talk to them about the next models as well."
Anthropic unveiled Mythos on April 7, describing it as its most capable model to date for coding and for agentic tasks. Beyond Clarks statement that discussions are underway, the companies and officials involved have not disclosed which specific agencies are participating in the talks or the precise nature of those conversations.
The limited public details leave open several uncertainties about the trajectory of government engagement with Anthropic. The companys outreach to the administration follows an official prohibition by the Pentagon and a near-term contract termination, but Clarks remarks indicate Anthropic intends to brief government stakeholders on Mythos and subsequent models.
Contextual note: Public statements to date set out Anthropics intent to engage, the Pentagons earlier supply-chain designation and the companys April 7 announcement of Mythos, while the identities of participating agencies and the substance of the talks remain unspecified.
