Yes. On September 12, 2026, Anthropic CEO Dario Amodei published an essay titled “We Must Pace the Frontier,” arguing that frontier AI labs should slow the rate of capability advances so safety, alignment, and third-party evaluation can keep up.
He stressed that “pacing” does not mean halting model training, and he committed Anthropic to giving embedded third-party evaluators employee-like access. OpenAI CEO Sam Altman and Elon Musk publicly said they agreed with the call to pace the frontier.
