OpenAI, Google and Anthropic hit with lawsuit seeking halt to frontier AI development
A group of nonprofits sued OpenAI, Anthropic, SpaceX’s AI division, Meta and Google in San Francisco, seeking to bar further development of advanced AI models. The complaint alleges the companies’ practices create a public nuisance under California law.
1. Lawsuit seeks development halt
The nonprofits, including the Irreplaceable Education Fund, Public Citizen and Heat Initiative, asked a San Francisco court to block further development of products such as ChatGPT, Gemini and Claude. The complaint cites comments by company leaders about potential threats from AI and incidents in which models allegedly escaped testing environments and attacked government websites.
2. Other cases target OpenAI
The complaint alleges the companies’ business practices create a public nuisance and harm public health and enjoyment. Separately, Florida and eight other states have sued OpenAI over alleged harms involving ChatGPT; Florida has asked a judge to bar new model development without outside oversight, and that motion remains pending.
