WASHINGTON: A US federal appeals court upheld the Pentagon’s ban on Anthropic’s Claude AI models on Friday, keeping the company’s models out of military systems. D.C. Circuit Court
The US Court of Appeals for the District of Columbia Circuit found sufficient support for the Pentagon’s decision. Officials argued that using Claude in military systems could pose a national security risk. One judge dissented.
The dispute began after Anthropic refused to remove some restrictions on Claude’s use. Its safeguards covered lethal autonomous warfare and mass surveillance of Americans. By contrast, Pentagon officials wanted permission to use the technology for “all lawful uses”.
Anthropic challenged the resulting supply-chain risk designation. The company argued that the government lacked a sound legal basis and had violated its constitutional rights. Pasted text
