Zuckerberg rejects coordinated AI slowdown after Muse delay

The standoff follows a specific sequence. Zuckerberg's September 15 comments came days after Anthropic CEO Dario Amodei called for outside scrutiny and coordination over the pace of AI development, and after Meta's own September 8 announcement of Muse, an agent that can send emails and book travel through a dedicated virtual computer and browser. Zuckerberg's argument is that Meta already works with independent evaluators and that reliable behavior is a selling point for users, so a lab can absorb a delay without demanding that competitors do the same.

Amodei's proposal, "We Must Pace the Frontier," calls for embedded outside evaluators, coordination among democracies, and global coordination. Anthropic has committed on its own to the evaluator plan, under which reviewers would get access similar to what employees have and the right to publish unfavorable findings, subject to confidentiality restrictions. That creates a concrete question about how much access and freedom outside reviewers should receive.

The larger landscape is split rather than neatly grouped. Sam Altman and Elon Musk endorsed Amodei's September 12 call, Demis Hassabis has backed its direction with details unresolved, and Altman supports pacing alongside continued progress. Nvidia CEO Jensen Huang argues speed and safety can coexist, while Donald Trump opposes efforts to obstruct AI and data center development and China's Foreign Ministry has opposed the slowdown proposal. Still, a narrower agreement on outside review may be possible, since both Zuckerberg and Amodei support outside scrutiny in different arrangements. With major players resisting coordination, acceleration appears to be the default.
