# Update a model group
|
||
|
|
|
||
|
|
To update a model group, send a `PUT` request to the `model_groups` endpoint and provide the ID of the model group you want to update.
|
||
|
|
|
||
|
|
When updating a model group, the following restrictions apply:
|
||
|
|
|
||
|
|
- The model owner or an admin user can update all fields. Any user who shares one or more backend roles with the model group can update the `name` and `description` fields only.
|
||
|
|
- When updating the `access_mode` to `restricted`, you must specify either `backend_roles` or `add_all_backend_roles` but not both.
|
||
|
|
- When updating the `name`, ensure the name is globally unique in the cluster.
|
||
|
|
|
||
|
|
For more information, see [Model access control]({{site.url}}{{site.baseurl}}/ml-commons-plugin/model-access-control/).

## Updating a model group in a cluster where model access control is disabled
|
||
|
|
|
||
|
|
If model access control is disabled on your cluster (one of the [prerequisites](ml-commons-plugin/model-access-control/#model-access-control-prerequisites) is not met), you can update only the `name` and `description` of a model group but cannot update any of the access parameters (`model_access_name`, `backend_roles`, or `add_backend_roles`).
