A new class action lawsuit filed in California federal court sues 4 frontier AI labs over an alleged "AI slowdown" pact, claiming coordinated limits on AI development violate Section 1 of the Sherman Act.
Key points:
- The complaint traces the alleged agreement to September 12, when Anthropic CEO Dario Amodei urged industrywide coordination to limit unchecked AI progress, followed by other executives.
- Core argument: "The antitrust laws do not permit competitors to decide among themselves that competition is too dangerous. Whether frontier AI should develop more slowly is a question for each company acting alone, or for Congress and the agencies."
- "A firm that slows alone loses customers, revenue, and technological leadership. Amodei's proposal solved that the way cartels always have: by agreeing to slow together, so no participant bears the competitive cost of restraint."
- The suit also argues an agreement that slows improvement lowers the quality subscribers receive.
Early-stage and unproven, but novel in framing AI safety coordination as an antitrust violation.
