On October 9, 2025, Microsoft CEO Satya Nadella revealed the company's first massive AI system, referred to as an AI factory, during a tweet. This system, part of Microsoft Azure's global data centers, consists of over 4,600 Nvidia GB300 rack computers utilizing the Blackwell Ultra GPU chip. Microsoft plans to deploy hundreds of thousands of these GPUs worldwide. The timing of this announcement is significant, coinciding with OpenAI's recent agreements with Nvidia and AMD for data center expansions. Microsoft boasts over 300 data centers across 34 countries, asserting its readiness to support the demands of frontier AI, capable of running models with hundreds of trillions of parameters. Further details on Microsoft's AI initiatives are expected at the upcoming TechCrunch Disrupt event.
