Anthropic Files Suit In Pentagon AI Dispute

“Anthropic filed a lawsuit Monday against the Trump administration for designating the artificial-intelligence company a security threat and trying to cancel its federal contracts.

 

Shortly after Anthropic filed its lawsuit, 37 AI researchers at competitors OpenAI and Google filed a brief urging the court to side with Anthropic, highlighting how the fight has rippled through Silicon Valley.

 

In designating Anthropic a supply-chain risk for the Pentagon and directing agencies to cut ties with the company, the administration went beyond its statutory authority with harsh retaliation because Anthropic didn't agree on how AI should be used by the Defense Department, the company argued.

 

"Defendants are seeking to destroy the economic value created by one of the world's fastest-growing private companies, which is a leader in responsibly developing an emergent technology of vital significance to our nation," Anthropic said in its complaint filed in the Northern District of California. The company asked the court to declare the moves unlawful and said that the case is critical for other businesses that may disagree with the government.

 

Anthropic listed the Defense Department, Defense Secretary Pete Hegseth, a host of federal agencies and many other administration officials as defendants.

 

"President Trump will never allow a radical-left, woke company to jeopardize our national security by dictating how the greatest and most powerful military in the world operates," a White House spokeswoman said.

 

The Defense Department declined to comment.

 

The group of 37 researchers from ChatGPT maker OpenAI and Google supporting Anthropic includes Jeff Dean, chief scientist at Google's DeepMind AI lab. Dean has been an architect of Google's AI strategy and works closely with Google DeepMind Chief Executive Demis Hassabis. Dean and the other researchers backed Anthropic's concerns about guardrails.

 

In contract negotiations with the Defense Department, Anthropic wanted explicit guarantees that its AI tools wouldn't be used for mass domestic surveillance or autonomous weapons. The Pentagon said it wouldn't do those things and always follows the law, so the company should trust it to use AI in all lawful scenarios.

 

The clash escalated on Feb. 27 when Hegseth said he would designate the company a supply-chain risk, an action normally used on businesses from overseas adversaries. The designation requires top Pentagon officials to demonstrate there is a security threat.

 

"Seeking judicial review does not change our longstanding commitment to harnessing AI to protect our national security, but this is a necessary step to protect our business, our customers and our partners," an Anthropic spokeswoman said.” [1]
