US government tightens AI procurement rules. The Trump administration has established strict guidelines for civilian artificial-intelligence contracts, requiring companies to grant the government an irrevocable license to use their AI systems for all lawful purposes. This move follows a significant clash between the Pentagon and Anthropic, which the Defense Department designated a supply-chain risk after months of disputes over safety safeguards. The General Services Administration has terminated Anthropic's OneGov deal, ending the company's access to federal contracts across executive, legislative, and judicial branches. New guidelines mandate that AI contractors cannot encode partisan or ideological judgments into systems and must disclose modifications made to comply with non-US regulatory frameworks.
