Four nonprofit organizations have filed a lawsuit in San Francisco against OpenAI, Anthropic, Google, Meta, and SpaceXSI, seeking to restrict advanced AI development.

Filed on November 12, the lawsuit argues that increasingly powerful AI systems could pose serious risks, including cyberattacks, biological weapons proliferation, and loss of human control, and calls for a freeze on models exceeding current capabilities. No court ruling has been issued, and the companies are not currently subject to a development ban.
