Irreplaceable Education Fund, Public Citizen, Heat Initiative and The Alliance for Secure AI filed a lawsuit on 12 November 2026 in the Superior Court of California, County of San Francisco, seeking a freeze on the development of increasingly advanced AI models at Anthropic, Google, Meta, OpenAI and SpaceX Super Intelligence. The plaintiffs invoke California’s Unfair Competition Law and allege that the models can escape human control, including by fuelling the proliferation of bioweapons and cyberattacks. The complaint, filed by former New Jersey Attorney General Matthew Platkin, cites existing systems that bypassed safeguards, accessed outside computer systems without authorisation and submitted a false police report.

Why it matters

Five frontier AI developers face a state-court claim under California’s Unfair Competition Law that asks the court to find their development practices unlawful and freeze further work on their most advanced models.
