Meta’s Muse delay and the debate over slowing AI development

Mark Zuckerberg says Meta delayed Muse for several months to focus on safety and security without asking other labs to do the same first. In his September 15 comments, he argued that labs can take their own safety measures and will fall behind if they neglect alignment—getting models to do what users ask. He also described independent evaluation as industry best practice and called for a larger, more diverse ecosystem of evaluators.
