Microsoft Deploys Massive Nvidia Blackwell Ultra GPU Clusters to Compete with OpenAI's Data Center Expansion

Microsoft CEO Satya Nadella announced the deployment of the company's first large-scale AI system comprising over 4,600 Nvidia GB300 rack computers with Blackwell Ultra GPUs, promising to roll out hundreds of thousands of these GPUs globally across Azure data centers. The announcement strategically counters OpenAI's recent $1 trillion commitment to build its own data centers, with Microsoft emphasizing it already possesses over 300 data centers in 34 countries capable of running next-generation AI models. Microsoft positions itself as uniquely equipped to handle frontier AI workloads and future models with hundreds of trillions of parameters.

Reflection AI Raises $2B to Build Open-Source Frontier Models as U.S. Answer to DeepSeek

Reflection, founded by former Google DeepMind researchers, raised $2 billion at an $8 billion valuation to build open-source frontier AI models as an American alternative to Chinese labs like DeepSeek. The startup, backed by major investors including Nvidia and Sequoia, plans to release a frontier language model next year trained on tens of trillions of tokens using Mixture-of-Experts architecture. The company aims to serve enterprises and governments seeking sovereign AI solutions while releasing model weights publicly but keeping training infrastructure proprietary.
