The Pentagon has reaffirmed that Anthropic remains blacklisted as a national security risk, even as officials separately assess the implications of its advanced AI model, Mythos, according to CNBC.
Defense Department CTO Emil Michael said Mythos represents a broader cybersecurity concern due to its ability to detect and fix vulnerabilities.
WSJ: The White House has blocked Anthropic’s push to expand access to Mythos, Anthropic's new powerful model that can reportedly find and exploit software flaws at a level serious enough to trigger national-security controls.

The report said Anthropic was designated a supply chain risk after failing to reach an agreement with the Department of Defense over how its AI tools would be used.
As a result, contractors must certify they are not using Anthropic’s models. The company has challenged the decision in court.
Michael noted that guardrails around AI use remain under negotiation across the industry. Meanwhile, the Pentagon has signed agreements with major tech firms including OpenAI, Google, and Microsoft to deploy AI systems on classified networks for operational use.
