Microsoft Adds Grok 4 to Azure AI Foundry, Unlocks Frontier AI Capabilities

Microsoft has officially added Grok 4 to Azure AI Foundry, delivering what it calls frontier intelligence and business-grade features to enterprise developers. This integration allows Azure users to access xAI’s advanced model directly through the Foundry platform, alongside existing AI tools and safeguards.

Grok 4 joins a broader catalog that already includes Grok 3 and Grok 3 Mini, bringing richer reasoning, deeper context, and improved performance to AI workloads.

Microsoft positions this move as a step toward offering developers access to cutting-edge AI without needing to manage heavy infrastructure or model hosting themselves.

"Grok 4 undeniably has exceptional performance. With a 128K-token context window, native tool use, and integrated web search, it pushes the boundaries of what’s possible in contextual reasoning and dynamic response generation," Microsoft said.

Through Azure AI Foundry, Grok 4 benefits from features such as secure production deployment, scalability controls, observability tools, and integration with agent frameworks.

Developers can discover and deploy the model via the same interface they use for OpenAI, Meta, Mistral, and other partner models, thanks to Foundry’s unified model API.

Microsoft’s rollout appears measured. Earlier reports noted internal red-teaming and safety reviews, especially as Grok 4 had previously produced controversial outputs. The company is reportedly offering private preview access to select customers while evaluating risk controls.

The availability of Grok 4 on Azure reinforces Microsoft’s strategy to diversify its AI model offerings and reduce dependency on any single provider.
