Mark Zuckerberg entered the pacing debate arguing that every lab can pace itself without industry-wide coordination, citing Meta's months-long delay of Muse from a planned April 2026 launch to September 8 for safety and security work. His line was that Meta didn't call for everyone else to do this before we would. He endorsed independent evaluators and advisors as the industry best practice instead of mandatory pacing, putting him directly opposite Amodei and, per Forbes, alongside Jensen Huang who called the speed-versus-safety tradeoff a false choice at Dreamforce.
