Microsoft on Monday became one of the first hyperscalers to provide managed access to Grok, the AI model developed by billionaire Elon Musk's AI startup, xAI.

Microsoft and xAI are coming together for their first major partnership. Announced at Microsoft’s Build developer conference, the company is including xAI’s Grok 3 and Grok 3 Mini on the list of models available through Azure AI Foundry.

“These models will have all the service level agreements (SLAs) Azure customers expect from any Microsoft product,” says Microsoft. The Grok AI models will be hosted and billed directly by Microsoft, and offered to its own product teams and customers through its Azure AI Foundry service.
