Meta announces Prometheus, a gigawatt-scale AI supercluster with nearly one million GPUs
Meta has revealed Prometheus, its most ambitious AI infrastructure project to date. Located in New Albany, Ohio, the supercluster is designed to train next-generation foundational models at an unprecedented scale. The first phase is already complete and was used to train the company's Muse family of models. At full scale, Prometheus will comprise roughly one million GPUs distributed across multiple interconnected buildings, all functioning as a single machine. The facility features advanced closed-loop liquid cooling and multi-generational NVIDIA hardware including GB200 and GB300 platforms.
