💼 Subscribers File Antitrust Lawsuit: Anthropic, OpenAI, xAI, and Google Accused of AI Slowdown Collusion

Four paying subscribers to ChatGPT, Claude, Grok, and Gemini have filed suit in the U.S. District Court for the Northern District of California, alleging that the companies illegally coordinated an AI slowdown, leaving subscribers shortchanged on the value of their paid services. The lawsuit was prompted by Dario Amodei's essay 'pacing the frontier.'

🌍 The court will now examine the line between public calls for 'pacing' and antitrust collusion: a win for the plaintiffs would make any formal agreements between AI labs risky.

👤 This is the first major lawsuit where paying subscribers are the consumers who bear the cost of the slowdown: models and features are released more slowly at the same price. For now, these are only the plaintiffs' claims.
