The short version

U.S. District Judge Rita Lin ruled Thursday that the Pentagon unconstitutionally retaliated against AI startup Anthropic by designating it a supply chain risk.
The legal battle arose after Anthropic refused to allow its Claude AI models to be used for mass surveillance or autonomous armed weapons.
The ruling vacates the risk designation and orders the Pentagon to rescind directives restricting federal contractors from using Anthropic's technology.
The government is expected to appeal the decision, while a separate, related lawsuit filed by Anthropic remains pending in a Washington, D.C., federal appeals court.
