Meta's Prometheus supercluster trained Muse Wonder models at gigawatt scale
The numbers reveal that training efficiency, not raw GPU count, is becoming the differentiator at frontier scale — 47K GPU hours between interruptions means far fewer wasted restarts than typical clusters. Infrastructure engineers and ML leads planning large-scale runs can study Meta's published tech overview for host-failure handling patterns. The Ohio location also signals Meta's US Midwest buildout amid national compute competition.
Meta revealed that it trained its Muse foundational models, including Muse Wonder, at Prometheus, a gigawatt-scale supercluster in New Albany, Ohio. The cluster spans hundreds of thousands of GPUs, where a single underperforming host can slow an entire training run. Meta engineered Prometheus for resilience, reporting 85%+ goodput on pretraining and 90%+ on reinforcement learning. During Muse Wonder training, the cluster recorded roughly 47K GPU hours of mean time between interruptions. Meta has also published a technical overview of the infrastructure behind Prometheus.
We trained our Muse foundational models, including Muse Wonder, at Prometheus, our gigawatt-scale supercluster in New Albany, Ohio. Across a supercluster with hundreds of thousands of GPUs, even one underperforming host can slow an entire training run. We engineered Prometheus for resilience at scale, achieving 85%+ goodput on pretraining, 90%+ on reinforcement learning and ~47K GPU hours mean time between interruptions during Muse Wonder training.
