The deployed system is a cluster of more than 4,600 Nvidia GB300 rack computers, which feature Nvidia\u2019s Blackwell Ultra GPUs and are connected with InfiniBand networking technology. Microsoft stated its plans include deploying \u201chundreds of thousands\u201d of these GPUs globally in systems capable of running next-generation AI models with \u201chundreds of trillions of parameters.\u201d<\/p>\n
The announcement follows recent high-profile deals made by Microsoft\u2019s partner, OpenAI, with Nvidia and AMD to build its own AI data centers. In 2025, OpenAI has reportedly made commitments estimated at up to $1 trillion for this effort, and CEO Sam Altman indicated this week that more deals were forthcoming.<\/p>\n
In its announcement, Microsoft highlighted its existing infrastructure of more than 300 data centers in 34 countries, stating they are positioned to meet the current demands of frontier AI.<\/p>\n
