Microsoft is making ‘significant investments’ in training its own AI models

Microsoft is ramping up its AI ambitions by investing heavily in computing capacity to develop its own frontier models, according to AI chief Mustafa Suleyman. While its first in-house model used just 15,000 H100 chips, the company plans to build clusters 6-10 times larger to compete with Meta, Google and xAI, while maintaining a pragmatic approach of using external models where needed.
