US judge blocks Pentagon’s Anthropic blacklisting

Anthropic's lawsuit in California federal court alleges that Defence Secretary Pete Hegseth overstepped his authority when he designated Anthropic a national security supply-chain risk, a label the government can apply to companies that expose military systems to potential infiltration or sabotage by adversaries.

Anthropic argues that AI models are not reliable enough to be ​safely used in autonomous weapons and that it opposes domestic surveillance as a violation of rights, but the Pentagon says private companies ‌should not ⁠be able to constrain military action.

In its March 9 lawsuit, Anthropic alleged the government violated its right to free speech under the First Amendment of the Constitution by retaliating ​against its views on AI ​safety.
