Microsoft has been steadily growing its Azure AI Foundry business over the past year, and has been quick to embrace models from a variety of AI labs that compete with Microsoft’s partner OpenAI. DeepSeek, the Chinese startup that shook up the world of AI earlier this year, forced Microsoft to move quickly to embrace its supercheap R1 model. The DeepSeek deployment on Azure AI Foundry was unusually fast for Microsoft, as I reported previously in Notepad, with Microsoft CEO Satya Nadella moving with haste to get engineers to test and deploy R1 in a matter of days.

I understand Nadella has been pushing for Microsoft to host Grok, as he’s eager for Microsoft to be seen as the hosting provider for any popular or emerging AI models. Microsoft’s Azure AI teams are constantly having to onboard new models or procure hardware that unlocks even more AI capabilities, in Microsoft’s bid to build an AI platform and turn AI agents into a digital workforce.
