On the opposite aspect is judicial administration of how, and thru whom, the Division of Warfare secures very important AI expertise throughout an energetic army battle. For that cause, we deny Anthropic’s movement for a keep pending evaluate on the deserves.”
With the cut up choices by the 2 courts, Anthropic is excluded from DOD contracts however is ready to proceed working with different authorities businesses whereas litigation performs out. Protection contractors shall be prohibited from utilizing Claude of their work with the company, however they’ll use it for different instances.

The corporate was the primary to deploy its fashions throughout the DOD’s labeled networks, and it was championed for its potential to combine with current Protection contractors like Palantir.
Anthropic signed a $200 million contract with the Pentagon in July, however as the corporate started negotiating Claude’s deployment on the DOD’s GenAI.mil AI platform in September, talks stalled.
The DOD needed Anthropic to grant the Pentagon unfettered entry to its fashions throughout all lawful functions, whereas Anthropic needed assurance that its expertise wouldn’t be used for totally autonomous weapons or home mass surveillance.
