Four subscribers to ChatGPT, Claude, Grok or Gemini filed a proposed class-action lawsuit alleging that leading AI developers agreed to slow AI development. The plaintiffs contend the alleged coordination, which they say began after a July 2026 statement by leading labs, would reduce value for paid AI subscribers. The case challenges a proposed approach to collective AI-safety restraint; it does not establish that an unlawful agreement occurred.
