Anthropic CEO Dario Amodei published an essay proposing to pace AI development. His plan includes using third-party evaluators, coordinating standards among democratic nations, and global cooperation on safety. Amodei clarified that pacing does not mean halting technical progress.

OpenAI CEO Sam Altman supported the proposal, confirming that OpenAI is discussing similar measures. Altman expressed support for a federal framework for safety requirements and independent evaluation. He emphasized that progress should be slower but not stopped.

Google DeepMind chair Demis Hassabis and SpaceX CEO Elon Musk expressed agreement with Amodei’s direction. Hassabis noted that the specific details of such a framework still require further development and discussion among industry leaders.

US political figures expressed skepticism regarding the slowdown. President Donald Trump rejected the idea, citing existing regulatory power. Vice President JD Vance described the industry's request for regulation as a potential trojan horse.

House Speaker Mike Johnson stated that a moratorium on AI development is not an option due to competition with China. He proposed a meeting with industry leaders to find a balance between national security and model safety.

Senator Bernie Sanders publicly supported the call to pause AI development, referencing a column by Peggy Noonan. The debate highlights a split between industry executives favoring structured safety pacing and political leaders focused on global competition.
