Anthropic has been designated as a supply chain risk to America's national security by the Department of War, which the company believes is not legally sound and plans to challenge in court. The designation primarily affects the use of Anthropic's AI model, Claude, by customers with contracts with the Department of War. Anthropic's CEO, Dario Amodei, apologized for an internal memo leak that was critical of the government's actions. The company is committed to supporting the national security community and advancing US national security.
