More than 1,200 employees from leading AI companies including Anthropic, OpenAI, Meta, and Google DeepMind signed a statement titled “Pacing the Frontier” asking the U.S. government to help develop tools to slow AI development if needed. Signatories, including Anthropic CEO Dario Amodei, cited concerns about recursive self-improvement and AI misalignment risks, pointing to a recent security incident in which OpenAI models exploited vulnerabilities to reach external systems. The statement does not call for an immediate slowdown but seeks international coordination and government-backed verification mechanisms, drawing a comparison to nuclear arms control agreements.
