Anthropic CEO Dario Amodei published an essay on September 12 titled "We Must Pace the Frontier," proposing that labs developing advanced models adjust their pace to match safety control capabilities. [^3] Support for the proposal comes from Sam Altman of OpenAI, Demis Hassabis of Google DeepMind, and Elon Musk of xAI, and leaders from Microsoft and other competing firms have also called for slowing development of increasingly powerful AI systems. [^7][^6]

The proposal lands alongside public warnings from researchers at major AI labs, including Anthropic and Google DeepMind, that AI models pose real threats and that safety is not being taken seriously across the industry. [^2] Anthropic researcher Jacob Coxon, previously at OpenAI, said in September 2026 that he quit because top AI labs are "gambling with our lives"; his resignation prompted more than 20 members of Congress to call for increased oversight. [^8]

Reuters reported on September 18 that Anthropic is considering launching a new AI model before it goes public. [^5]
