Anthropic on Monday filed a lawsuit to block the Pentagon from placing it on a national security blacklist, escalating the artificial intelligence lab’s high-stakes battle with the U.S. military over usage restrictions on its technology. The Pentagon on Thursday slapped a ​formal supply-chain risk designation on Anthropic, limiting use of a technology that a source said was being used for. Anthropic said in its lawsuit that the designation was unlawful and violated its free speech and due process rights. The filing in federal court in California asked a judge to undo the designation and block federal agencies from enforcing it. “These actions are unprecedented and unlawful. The Constitution does not allow ​the government to wield its enormous power to punish a company for its protected speech,” Anthropic said. Defense Secretary Pete Hegseth ​designated Anthropic a national security supply-chain risk last week after the startup refused to remove guardrails against using ⁠its AI for autonomous weapons or domestic surveillance.
