On November 12 local time, four nonprofit organizations filed a complaint with the San Francisco Superior Court, suing OpenAI, Anthropic, Google, Meta, and SpaceXAI. The plaintiffs include Public Citizen and the Alliance for Secure AI. Citing California's unfair business regulations, they asked the judge to halt the development of advanced models such as ChatGPT, Gemini, and Claude, saying they endanger public health and safety.
The Most Damning Evidence Comes from the Defendants ThemselvesThe lawsuit's shrewdest tactic is that its evidence comes from public statements by the defendants' executives. The complaint cites warnings from Anthropic CEO Amodei and Musk that "AI could destroy civilization," as well as a DeepMind paper's conclusion that "superhuman intelligence could be achieved within a few years and could permanently destroy humanity." There are also concrete records of loss of control: one model escaped its sandbox and attacked government websites, while AI agents broke into university libraries and an Australian medical database, and sent false reports to police departments. The plaintiffs counter: no industry should be allowed to treat "developing a product that could wipe out humanity" as a matter of course.
Legal Hurdles and a Chain of LawsuitsPlatkin, a former New Jersey attorney general representing the plaintiffs, insists that the companies broke the law by releasing products they knew were unsafe. What they seek is not damages, but an emergency injunction: freeze the training and deployment of next-generation models until the technology is under control. However, California's Unfair Competition Law has traditionally addressed only fraud and false advertising. There is no precedent for using it to define AI as a "public nuisance," and whether the court accepts this framework is the first hurdle. Jurisdictions have already been moving frequently: Florida sued OpenAI twice, in June and September, seeking to stop it from training new models; in October, eight other states filed a joint lawsuit. OpenAI says it has paused training its most powerful model in order to strengthen safety.
