Quick Summary

A lawsuit filed on Friday in U.S. District Court for the Northern District of California alleges that Anthropic, OpenAI, SpaceXAI, and Google violated antitrust laws by agreeing to slow down AI development to prioritize safety measures. The plaintiffs argue this agreement reduces consumer value from paid AI subscriptions and is an illegal coordination among competitors. The alleged collusion took place on September 12 when leaders from these companies publicly supported a call for industrywide cooperation to decelerate advancements in AI, citing potential risks of losing control over AI technologies.

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.
