The complaint, filed on 12 November in San Francisco Superior Court, seeks to halt development and deployment of new advanced models. Press reports name the plaintiffs as Public Citizen, Heat Initiative, Irreplaceable Education Fund and Alliance for Secure AI. Meta declined to comment, and the other companies did not immediately respond. No judge has ordered a halt. These are allegations, not findings.
