The Pentagon replaced Anthropic’s AI with Elon Musk’s Grok in classified systems, citing unrestricted access demands.

The U.S. Pentagon has approved Elon Musk’s xAI to deploy its Grok AI in classified military systems, replacing Anthropic’s Claude, which was restricted from use in autonomous weapons and mass surveillance. The shift follows pressure on Anthropic to allow “all lawful purposes” access, a demand the company refused. Grok, despite past issues with harmful content, agreed to the Pentagon’s terms. The department is also negotiating with Google and OpenAI for classified AI use, aiming to diversify its AI partnerships while ensuring security and reliability.
