Block models for an organization

The organization's Models page blocks models in every workspace of the organization at once.

You must be an organization Admin. Open Settings > Models under Organization · "name".

The organization Models page of Acme Group with Restrict models on and Claude Opus 4.6 turned off

Block or unblock a model

Restrict models is off until you block a model: every workspace of the organization can use every model, including models added later.

Turn Restrict models on.
Turn a model's switch off to block it, or on to unblock it. Each change applies at once.

Models added to the deployment later are allowed until someone blocks them.
The last model that is not blocked cannot be blocked.
Turning Restrict models off asks first, then unblocks every model you blocked.
Blocked by the platform marks a model your Alomana administrator blocked for the organization. Only they can unblock it.
The block applies only in the organization's workspaces, never in its members' other workspaces.

Each workspace also has its own model list. See Choose the workspace's models.

Organization	Workspace	Can people use the model there?
Allowed	On	Yes
Allowed	Off	No
Blocked	Any	No. The workspace shows it as Blocked by your organization and cannot turn it on.
