 ## Setup 
 
 To use the Deep Research tool, you need to create the Azure AI Foundry type project, add your Grounding with Bing Search resource as a new connection, deploy the `o3-deep-research-model`, and deploy the selected Azure OpenAI GPT model. 
 
+> [!NOTE]
+> * The Azure AI Foundry, the `o3-deep-research` model, and the GPT model for intent clarification should all be in the same region. Supported regions are **West US** and N**orway East**.
