A coalition of nonprofit organizations filed a lawsuit against five leading artificial intelligence companies on Thursday, seeking to halt the development of advanced AI models on the grounds that the technology could pose severe threats to humanity.
The legal action, brought before the San Francisco Superior Court by the Alliance for Secure AI, together with the Irreplaceable Education Fund, Public Citizen and the Heat Initiative, targets Anthropic, Google, Meta, OpenAI and SpaceX Super Intelligence (SpaceXSI).
Brendan Steinhauser, CEO of the Alliance for Secure AI, accused technology executives of continuing to advance increasingly sophisticated AI systems despite having previously acknowledged the potentially catastrophic consequences.
Steinhauser argued that the companies were accelerating the development and commercialization of powerful AI technologies without being able to guarantee their safety or ensure they remained under reliable control. He also raised concerns about the growing use of AI systems to conduct their own research and development.
None of the five companies immediately responded to requests for comment on the lawsuit.
The case comes amid mounting concerns about AI safety after several reported incidents in which autonomous AI agents allegedly performed unauthorized actions.
According to the lawsuit, the risks could intensify as developers increasingly employ AI models to design and improve successive generations of AI systems with limited human oversight.
This process, commonly referred to as "recursive self-improvement," could make advanced AI technologies progressively harder to control, the plaintiffs argue.
"Defendants know these systems do not consistently act in accordance with their intentions," the lawsuit states.
"And Defendants know there is no reliable method to control their AI systems and prevent them from causing harm."
The nonprofit organizations also cited previous statements by leading AI executives acknowledging the potential dangers associated with the technology.
In 2015, OpenAI CEO Sam Altman warned that artificial intelligence could potentially bring about the end of humanity. Similarly, Anthropic CEO Dario Amodei estimated in 2025 that there was a 25% chance that AI development would result in catastrophic consequences.
Amid increasing scrutiny of AI safety, technology executives have emphasized their commitment to responsible development and stronger safeguards.
In October, prominent industry figures, including Altman, Amodei and SpaceX CEO Elon Musk, expressed support for a coordinated slowdown in the development of AI.
Their statements followed a warning from an Anthropic researcher who estimated that artificial intelligence posed a 10% risk of causing human extinction.
