Microsoft is bringing the Grok 3 and Grok 3 mini AI models from Elon Musk’s xAI to its Azure AI Foundry platform, as new offerings hosted and billed directly by Microsoft from within the company’s cloud platform.

Microsoft will host technology from Elon Musk's xAI on its cloud servers, despite criticism over xAI's recent controversial content. Musk addressed concerns about the performance of xAI's models at a Microsoft even.

Starting this week, users of Azure AI Foundry will be able to purchase licences for xAI’s models under the same commercial terms as OpenAI’s — including premium access to cloud computing power and integration into Microsoft’s enterprise tools. This development gives developers “service parity” whether they choose Musk’s models or those from OpenAI.
