❯ Zuckerberg calls safety alignment a competitive capability, says Muse was delayed for months

Company statementMark Zuckerberg said in a post on X that labs have a responsibility to proceed at the pace safe training requires, as well as commercial incentives to achieve alignment. Users do not want agents that act against their wishes, he said, while harm can also create legal liability.

Release decisionsHe disclosed that Meta had delayed Muse for months to strengthen safety and safeguards without asking other companies to take the same action first. Addressing arguments for slowing capability advances while alignment catches up, he said trust and alignment themselves were becoming differentiating capabilities for models and agents, and labs neglecting them would fall behind.

Evaluation plansZuckerberg also said Meta Superintelligence Labs had engaged independent evaluators and advisers in several areas and supported greater diversity among evaluation organizations. He reiterated that a significant majority of compute would go toward serving users rather than racing toward recursive self-improvement. The post did not disclose an exact compute allocation or complete evaluation results.

▪ SIGNALMeta disclosed a release delay, external evaluators and a commitment on compute use; exact resource allocations and full evaluation results remain absent from the statement.
