The United States National Security Agency is utilizing Anthropic's Mythos Preview AI tool despite a formal supply-chain risk designation from the Pentagon. The model is reportedly being used more widely within the department.

A federal judge in California has blocked the Pentagon's attempt to label Anthropic as a supply chain risk, ruling that this action violated the company's constitutional rights. The judge stated that no statute supports branding an American company as a potential adversary for expressing disagreement with the government.

Anthropic has filed a lawsuit against the Trump administration to challenge the designation of its operations as a 'supply chain risk.' The company seeks to reverse this classification, which could impact its business activities.

The Pentagon has officially designated Anthropic as a supply-chain risk, indicating that the company's AI tools pose security threats. As a result, Anthropic will be cut off from partners that collaborate with the Defense Department.

OpenAI stated that it does not consider Anthropic to be a supply chain risk and has communicated this position to the Department of War.
