 Azure OpenAI Service is committed to providing the best generative AI models for customers. As part of this commitment, Azure OpenAI Service regularly releases new model versions to incorporate the latest features and improvements from OpenAI.
 
 In particular, the GPT-3.5 Turbo and GPT-4 models see regular updates with new features.  For example, versions 0613 of GPT-3.5 Turbo and GPT-4 introduced function calling.  Function calling is a popular feature that allows the model to create structured outputs that can be used to call external tools.

 ## How model versions work
 
 We want to make it easy for customers to stay up to date as models improve.  Customers can choose to start with a particular version and to automatically update as new versions are released.

 Customers can also deploy a specific version like GPT-4 0314 or GPT-4 0613 and choose an update policy, which can include the following options:

 * Deployments that are set to **No Auto Upgrade** stop working when the model is retired.
 
+### VersionUpgradeOption
+
+You can check what model upgrade options are set for previously deployed models in [Azure OpenAI Studio](https://oai.azure.com). Select **Deployments** > Under the deployment name column select one of the deployment names that are highlighted in blue > The **Properties** will contain a value for **Version update policy**.
+
+The corresponding property can also be accessed via [REST](../how-to/working-with-models.md#model-deployment-upgrade-configuration), [PowerShell](/powershell/module/az.cognitiveservices/get-azcognitiveservicesaccountdeployment), and [Azure CLI](/cli/azure/cognitiveservices/account/deployment#az-cognitiveservices-account-deployment-show).
+
+|Option| Read | Update |
+|---|---|---|
+| [REST](../how-to/working-with-models.md#model-deployment-upgrade-configuration) | Yes. If `versionUpgradeOption` is not returned it means it is `null` |Yes |

+| [Azure CLI](/cli/azure/cognitiveservices/account/deployment#az-cognitiveservices-account-deployment-show) | Yes. It shows `null` if `versionUpgradeOption` is not set.| *No.* It is not possible to update the version upgrade option.|

 ## How Azure updates OpenAI models
 
 Azure works closely with OpenAI to release new model versions.  When a new version of a model is released, a customer can immediately test it in new deployments.  Azure publishes when new versions of models are released, and notifies customers at least two weeks before a new version becomes the default version of the model.   Azure also maintains the previous major version of the model until its retirement date, so customers can switch back to it if desired.
