Key point

NSA is using Anthropic's Mythos Preview despite a Department of Defense blacklist.

Details

It has been reported that the US NSA is using Anthropic's Mythos Preview AI tool.

This contradicts the situation in which the Department of Defense designated Anthropic as a supply-chain risk, putting the brakes on government contracts. Reuters, in reporting this, stated that it was unable to independently confirm it immediately.

  • Anthropic, the NSA, and the Department of Defense did not immediately respond to requests for comment.
  • Last week, the Trump administration and Anthropic CEO Dario Amodei discussed collaboration within the government.
  • Anthropic has been introducing Mythos as its most powerful coding and agentic model.
