Meta says Prometheus delivered 85% goodput while training Muse Wonder

Meta says its Prometheus supercluster in New Albany, Ohio, delivered more than 85% goodput during Muse Wonder pretraining and more than 90% during reinforcement learning.

• AI at Meta said in an October 19th post on X that the first phase of Prometheus trained Muse models, including Muse Wonder.
• The self-reported figures put reliability alongside GPU scale in Meta's frontier-model strategy and show the operational bottleneck it is trying to address as it builds toward a roughly 1 million-GPU cluster.
