Four Nonprofit Organizations Sue Five AI Companies, Demanding Freeze on Development of More Powerful Models

TechFlow reports that on November 15, according to Decrypt, four nonprofit organizations filed a lawsuit with the San Francisco Superior Court in California against OpenAI, Anthropic, Google, Meta, and SpaceX, seeking an immediate injunction to prevent these companies from developing or deploying AI systems more powerful than the most advanced models as of November 12, 2026.

The plaintiffs include Public Citizen, Heat Initiative, Irreplaceable Education Fund, and Alliance for Secure AI. The complaint also requests an injunction barring the defendants from using AI to independently conduct or direct research on more powerful models, and cites California's Unfair Competition Law, arguing that increasingly powerful AI systems may jeopardize public safety.

The report notes that the defendants have not yet been held liable, and warnings regarding potential catastrophic risks do not automatically constitute violations of California law.
