# UpdateHubContentReference
<a name="API_UpdateHubContentReference"></a>

Updates the contents of a SageMaker hub for a `ModelReference` resource. A `ModelReference` allows you to access public SageMaker JumpStart models from within your private hub.

When using this API, you can update the `MinVersion` field for additional flexibility in the model version. You shouldn't update any additional fields when using this API, because the metadata in your private hub should match the public JumpStart model's metadata.

**Note**  
If you want to update a `Model` or `Notebook` resource in your hub, use the `UpdateHubContent` API instead.

For more information about adding model references to your hub, see [ Add models to a private hub](https://docs.aws.amazon.com/sagemaker/latest/dg/jumpstart-curated-hubs-admin-guide-add-models.html).
