Story summary
A new lawsuit filed in the U.S. District Court for the Northern District of California on Friday alleges that Anthropic, OpenAI, SpaceXAI, and Google violated antitrust laws by agreeing to slow down their AI development efforts. On September 12, Anthropic CEO Dario Amodei published an essay urging industry-wide cooperation to decelerate advancements for enhanced safety, which was quickly endorsed by OpenAI's Sam Altman, SpaceXAI's Elon Musk, and Google DeepMind's Demis Hassabis. The plaintiffs argue that this coordination reduces the value consumers get from paid AI subscriptions, violating federal antitrust laws.
