 # Models supported by Azure AI Agent Service
 
-Agents are powered by a diverse set of models with different capabilities and price points. Model availability varies by region and cloud. Certain tools and capabilities require the latest models. The following models are available in the available SDKs. The following table is for pay-as-you-go. For information on Provisioned Throughput Unit (PTU) availability, see [provisioned throughput](../../openai/concepts/provisioned-throughput.md) in the Azure OpenAI documentation. You can use [global standard models](../../openai/concepts/models.md#global-standard-model-availability) if they're supported in the regions listed here.

 ## Azure OpenAI models
 
+Azure OpnAI models provide customers with choices on the hosting structure that fits their business and usage patterns. The service offers two main types of deployment: 
+
+- **Standard** is offered with a global deployment option, routing traffic globally to provide higher throughput.
+- **Provisioned** is also offered with a global deployment option, allowing customers to purchase and deploy provisioned throughput units across Azure global infrastructure.
+
+All deployments can perform the exact same inference operations, however the billing, scale, and performance are substantially different. To learn more about Azure OpenAI deployment types see our [deployment types guide](../../openai/how-to/deployment-types.md).
+
 Azure AI Agent Service supports the same models as the chat completions API in Azure OpenAI, in the following regions.
