The U.S. National Security Agency (NSA) is reportedly employing Anthropic's Mythos model, even though the Pentagon has classified Anthropic as a "supply chain risk." This development, reported by Axios, highlights a divergence in the approach to Anthropic's technology between different U.S. government entities. The Pentagon's blacklisting of Anthropic raises concerns about potential security vulnerabilities, yet the NSA's use of the Mythos model suggests a continued reliance on its capabilities.
