Meta’s engineering team on October 19, 2026 published a detailed technical account of Prometheus, the company’s gigawatt-scale AI supercluster in New Albany, Ohio, confirming its completed first phase trained the Muse foundational models and that Meta plans to scale the system to roughly 1 million GPUs. In a post on Meta’s engineering blog , Kevin Lee, Yashar Bayani, Ahmed Sharif, and Yee Jiun Song wrote that the first phase trained the Muse family, including the Muse Wonder frontier models, which Meta says deliver state-of-the-art performance on personal and professional agentic tasks. Two years before the disclosure, the New Albany site was a conventional data center running web traffic; Meta reworked it for frontier-model training and is building the supercluster in phases. Prometheus now comprises hundreds of thousands of GPUs spread across traditional and AI-optimized data center buildings and rapid-deployment structures, all operating as a single machine. …
