# View and Manage Model Group and Model Version Tags
Model Registry helps you view and manage tags related to your model groups. You can use tags to categorize model groups by purpose, owner, environment, or other criteria. The following instructions show you how to view, add, delete, and edit your tags in the Amazon SageMaker Studio console.
**Note**
Model packages in the SageMaker Model Registry do not support tags—these are versioned model packages. Instead, you can add key value pairs using `CustomerMetadataProperties`. Model package groups in the model registry support tagging.
