Anthropic sues to block Pentagon blacklisting over AI use restrictions

Anthropic on Monday filed a lawsuit to block the Pentagon from placing it on a national security blacklist, escalating the artificial intelligence lab’s high-stakes battle with the U.S. military over usage restrictions on its technology.

Anthropic said in its lawsuit that the designation was unlawful and violated its free speech and due process rights. The filing in federal court in California asked a judge to undo the designation and block federal agencies from enforcing it.
