NSA using Anthropic's Mythos despite Pentagon blacklist

The National Security Agency is using Anthropic's Mythos Preview model, even as the Department of Defense maintains the company is a supply chain risk and pursues legal action to cut it off. The Pentagon moved in February to blacklist Anthropic and force vendors to follow suit, yet the NSA and potentially other DoD units now have access to Mythos, one of roughly 40 organisations granted use of the model due to its offensive cyber capabilities. Anthropic CEO Dario Amodei met White House officials on Friday to discuss government use of Mythos. The contradiction highlights a rift between the Pentagon's contractual dispute with Anthropic over acceptable use policies and the intelligence community's need for cutting-edge security tools.
