Typically you can refer to the [region support](https://azure.microsoft.com/explore/global-infrastructure/products-by-region/?products=cognitive-services) for details, and most Language service capabilities are available in all supported regions. Some Language service capabilities, however, are only available in select regions which are listed below.

### Data augmentation feature in Custom Named Entity Recognition
109
+
110
+
The data augmentation capability allows users to use an Azure OpenAI model to generate supplementary training data during the creation of a custom named entity recognition model. This functionality is currently limited to select regions.
111
+
112
+
* All entity data utilized with data augmentation is required to include a description field.
113
+
* Supported Azure OpenAI model types for this feature are gpt-4o and gpt-4 32k.
114
+
* The language resource must also have the **Azure OpenAI Contributor** role assigned on the Azure OpenAI resource.
