Currently the AI assistant settings in ArcGIS Online only allow administrators to turn the assistants on or off for the entire organization. We would like to see control for use of AI assistants as a privilege that could be controlled for custom roles. The organization-wide setting would still be useful in that it could control whether the default roles (Publisher, Data Editor, etc.) have access to AI assistants.
In our case, we want to enable AI assistants for a subset of our named users (who have a custom role) but that is not possible with the way the settings exist right now. Our organization is not ready to enable the AI assistants for all users with access to the site.
