# User Groups

Organize teams and control assigned access

**User Groups** organize people into teams and can grant access to Models or Conversations. They can also be mentioned or used as task assignees where the feature supports it.

## Create or edit a User Group

1. Open **Workspace Settings → User Groups**.
2. Choose **Add User Group**, or select an existing group to edit it.
3. Set its name, color, and members.
4. Save the changes.

Only roles with sufficient Workspace permissions can manage groups.

## Set the code used in Model names

In a group's details, **External group** enables the optional **Code** field. Enter a code, such as `ACM`, and save. When creating Models, choose this group in **Append selected user group code** to add `_ACM` to their names. See [Add a Model](/en/workspace-management/model-operations/add-model.md).

## Assign groups to content

Assign one or more User Groups when creating or editing a Model or Conversation. You can also update shared group assignments for multiple Models from selection mode.

For Viewer members, assigning the group grants access to the parent item. Each message, file, Note, or Drive link normally must be made visible to Viewers. An Owner can grant an individual Viewer access to all files and Notes in accessible Models from [Role management](/en/workspace-management/workspace-administration/role-management.md).

## Filter and mention groups

Use User Group filters in the desktop sidebar to narrow the Models list. In a message or Note, use the mention picker to notify an eligible group. Group mentions notify the members who can access that content.
