Microsoft is getting ready to add Elon Musk’s Grok AI model to its Azure cloud service. This move could help developers build new apps using Grok’s technology. However, it also risks causing problems with Microsoft’s partner, OpenAI, the creator of ChatGPT.
Grok is an AI model made by Musk’s company, xAI. Microsoft wants to host Grok on Azure AI Foundry, a platform where developers can access tools to create AI apps. This means developers might soon use Grok for tasks like writing or data analysis. But Microsoft will only host Grok and not help train future versions of it.

Why Microsoft Is Adding Grok to Azure
Microsoft’s Azure AI Foundry already offers over 1,900 AI models, including ones from Google and Meta. By adding Grok, Microsoft wants to become the go-to place for AI developers. Satya Nadella, Microsoft’s CEO, has pushed the company to host popular AI models quickly. For example, when the Chinese startup DeepSeek released a cheap AI model, Microsoft added it to Azure in a few days.
A Microsoft leader said Azure aims to be the “operating system” powering all AI apps. Hosting Grok fits this goal. Developers could pick Grok for certain tasks, like humor or creativity, while using other models for different needs.
Tension With OpenAI
Why OpenAI Is Unhappy
Microsoft’s partnership with OpenAI is shaky. OpenAI recently sued Musk, accusing him of trying to slow its progress. Musk helped start OpenAI but left in 2018. Now, Microsoft hosting Musk’s Grok could make things worse.
Reports say Microsoft and OpenAI are growing apart. Microsoft hired Mustafa Suleyman, a former Google AI leader, as a backup plan. However, Microsoft still relies on OpenAI’s models for products like Copilot. Delays to OpenAI’s GPT-5 model have also frustrated Microsoft.
What Grok on Azure Means for Developers
If Microsoft adds Grok to Azure AI Foundry, developers could
- Build apps using Grok’s unique features, like its “rebellious” personality.
- Mix Grok with other AI models for more powerful tools.
- Avoid depending only on OpenAI’s technology.
However, Grok might not stay exclusive to Azure. Amazon or Google could also host it, letting developers choose where to use it.

Risks for Microsoft
Hosting Grok is risky. The government project DOGE has become controversial to the extent that it irritates several Microsoft staff members. Musk plans to leave DOGE this month, possibly around the time Microsoft announces Grok at its Build conference.
Microsoft also faces challenges with its own AI projects. Efforts to create AI models that rival OpenAI have failed, forcing Microsoft to keep using OpenAI’s tech.
