Microsoft has formally intervened in a legal battle between Anthropic and the Pentagon, warning that a 'national security supply-chain risk' designation against the AI firm could cripple U.S. military capabilities. The dispute centers on Anthropic's refusal to allow its Claude AI models to be used for autonomous lethal warfare, leading to an unprecedented blacklisting typically reserved for foreign adversaries.
Major investors including Amazon and Lightspeed are moving to de-escalate a high-stakes conflict between Anthropic and the Department of War over AI safety protocols. The dispute centers on Anthropic's refusal to allow its Claude AI to be used for autonomous weapons or mass surveillance, risking a total ban from federal defense work.
