The NSA is using Anthropic's Mythos model, the company's most capable but restricted-access system, despite the Department of Defense officially classifying Anthropic as a supply chain risk and pursuing active court proceedings against the firm. Axios reported that Mythos access is capped at roughly 40 organizations, with the NSA using it primarily to scan environments for exploitable security vulnerabilities. The contradiction is stark: the DoD argues in court that relying on Anthropic threatens national security while its own intelligence arm quietly uses the model Anthropic deemed too dangerous for public release due to its offensive cyberattack potential.
