The Department of Defense is currently arguing in two federal courts that Anthropic is a supply chain risk to national security. The Department of Defense is also, via one of its agencies, using the very model that prompted the designation. Both of these are true, at the same time, and nobody in the building seems embarrassed about it.
Axios reported on Sunday that the National Security Agency has been given access to Mythos Preview, the cybersecurity model Anthropic announced earlier this month and then refused to release publicly on the grounds that it was too good at offence. Roughly forty organisations got keys. About a dozen have been named. The NSA is one of the undisclosed ones, and according to two sources, TechCrunch says the model is "being used more widely within the department" — meaning the rest of the intelligence community may already be touching it too. Primary use case: scanning environments for exploitable vulnerabilities. Offensive security dressed as defensive posture.
I've already written about Dario Amodei's trip to the West Wing on Friday, and about the Treasury inviting the company in six weeks after the Pentagon shut it out. Those were executive- branch moves — political, optical, arguably theatre. The NSA story is different. TechCrunch was careful to point out that the DoD is the NSA's parent agency. That matters. This isn't another department contradicting the Pentagon's position. This is the Pentagon, in effect, contradicting itself.
And yet one half of the department is in court saying the company's tools are a threat. The other half is using the tools.
What makes this less funny and more serious is what Mythos actually does. Anthropic said on release that the preview model had already uncovered "thousands" of major vulnerabilities across every major operating system and browser. That is not a research benchmark. That is a live capability. Reuters reported that Treasury and the Fed briefed US bank CEOs on the model's risks, and that UK authorities did the same with their own financial sector. When governments hold private briefings about a commercial AI release, it tends to mean either the model is being overhyped or the model is a weapon. The NSA presumably believes the second reading, which is also why they wanted it.
The OMB has now told federal agencies it is working on a "revised version" of Mythos with additional guardrails for broader civilian use. So the final shape of this is probably already visible: the Pentagon's supply-chain case continues in court as a matter of principle, Anthropic continues to sell a restricted frontier model to the agencies that can actually use it, and the policy machinery catches up by building a sanitised variant for everyone else. Litigation in one hand, procurement in the other.
One detail I can't stop thinking about. Trump was asked about Amodei's West Wing meeting on Friday and said he had no idea it had happened. That might be deniability, or it might be literally true. Either reading points to the same thing: the people deciding which AI companies are national security threats and the people deciding which AI companies get the keys are not, at the moment, the same people.
