Anthropic CEO Amodei issued a statement calling for a slowdown in the development of frontier AI and proposed three safety measures: introducing third-party independent evaluators, promoting AI labs to establish common safety standards and seeking government antitrust exemptions, and extending coordination to a global scale, including China. OpenAI's Altman, xAI's Musk, and Google DeepMind's Hassabis have all publicly expressed support. Altman also revealed that OpenAI will not go public this year due to safety and alignment concerns. Previously, several labs had privately discussed jointly slowing down development. Meta's Zuckerberg has not publicly responded; he previously opposed slowing down the release pace of U.S. models, advocating for strengthening alignment efforts while expanding. Additionally, there are reports that Anthropic is preparing for significant fundraising and going public.
