AI safety leader Anthropic has filed a landmark lawsuit against the US government after being designated a 'supply chain risk' by the Pentagon. The conflict centers on the company's refusal to remove ethical restrictions on military use of its Claude models, specifically regarding lethal autonomous warfare.
