Lawsuit Claims AI Giants Coordinated to Slow Development
A lawsuit says several major AI companies agreed to slow down how quickly they improve their systems.
The people suing say this could hurt customers who pay for AI services.
They point to public comments made after Anthropic CEO Dario Amodei called for more cooperation on AI safety.
OpenAI, SpaceXAI and Google DeepMind leaders responded publicly to his proposal.
The lawsuit argues that competitors making this kind of agreement could violate antitrust laws.
The plaintiffs are four paid subscribers seeking to represent other subscribers across the United States.
They also warn that private companies should not control AI safety agreements by themselves.
OpenAI CEO Sam Altman said he supported consistent government safety rules but did not think companies had to wait for special legal permission to begin safety work.
The companies named in the lawsuit had not immediately provided comments.
A proposed class-action lawsuit alleges Anthropic, OpenAI, SpaceXAI and Google unlawfully agreed to slow AI development.
The complaint was filed Friday in the U.S. District Court for the Northern District of California.
Plaintiffs say slower development could reduce the value customers receive from paid AI subscriptions.
The alleged coordination followed a September 12 essay by Anthropic CEO Dario Amodei calling for industry cooperation on deceleration and safety.
OpenAI CEO Sam Altman expressed support for consistent federal safety requirements, while representatives of the companies did not immediately comment.
