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 military operations in Iran. ADVERTISEMENTAnthropic said in its lawsuit that the designation was unlawful and violated its free speech and due process rights. 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. Microsoft-backed OpenAI announced a deal to use its technology in the Defense Department network shortly after Hegseth moved to blacklist Anthropic.
