NSA using Anthropic's Mythos model despite US blacklist

The US National Security Agency is reportedly using Anthropic's Mythos model, despite the company appearing on a government blacklist, according to Axios. The discrepancy raises questions about how federal procurement rules apply to AI models and whether exceptions exist for intelligence agencies. No further details on the nature of the blacklist, the NSA's use case, or Anthropic's response are available from the Reuters report. The story matters because it suggests a gap between stated policy and operational practice in government AI adoption.
