David Sacks, the White House’s top AI advisor, criticized OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei on September 13 for supporting Pace The Frontier, a movement seeking coordinated international action to slow the development of advanced AI systems. Launched on July 28, the initiative began with an open letter signed by over 1,134 people from major AI organizations, including Google DeepMind, Meta, OpenAI, and Anthropic employees; its signatories exceeded 1,300 by mid-September. The letter did not call for an immediate halt to AI research, but asked governments to support tools for coordinated policymaking on frontier AI. Sacks described related proposals, including antitrust exemptions for competitors coordinating on safety standards, as regulatory capture. He argued that restrictions could preserve the market positions of OpenAI and Anthropic while making it harder for new competitors to catch up, and said China was unlikely to join such an international effort. Sacks instead urged developers to voluntarily emphasize reliability and predictability, arguing that customer demand is already favoring dependable systems over products that maximize capabilities at the expense of consistency. The debate follows concerns about the autonomy and unpredictability of advanced AI, product liability risks involving platforms such as Hugging Face, and the bipartisan FRONTIER Act introduced in July.
