The Pentagon previously requested Anthropic, OpenAI, Google, and xAI allow the use of their AI models for “all lawful purposes,” to which Anthropic put up the most resistance over fears its AI models could be used for autonomous weapons systems and mass domestic surveillance.

A senior official in the Department of Defense accused Anthropic of "lying" about how the U.S. military intends to use the private tech firm's Claude AI system.

The administration is threatening both to blacklist the company and to force it to allow its Claude AI model to be used as the Pentagon wishes.

The Pentagon weighs a blacklist and Defense Production Act pressure on Anthropic, demanding "all lawful use" of Claude in classified systems.

Pentagon gives Anthropic until Friday to remove military restrictions on Claude AI model or face contract termination and Defense Production Act.

Defense Secretary Pete Hegseth gave Anthropic until Friday at 5 p.m. to grant the military unresticted use of its AI technology.

The US Pentagon is pressurising Anthropic to lift AI guardrails for US military use, giving the AI company a deadline until7.
