Hi , @Ma20114294 According to my experience and research, for the Gen2 version of Premium Capacity, there is a feature called Auto Scale that automatically adds one or more v-cores depending on the load level of the capacity, which will charge some fees after the automatic increase of V-cores, but this feature can be turned on or off.
For your Premium capacity, in principle, there will be no charge after subscription and purchase, if you are worried that too many workspaces are assigned, too many users used by the workspace resulting in excessive load, there is a function that triggers Auto Scale, you can try to limit the users of the capacity in the capacity settings, and disable, according to the needs of the new workspace creation option, or only allow some users to create new workspaces, depending on your specific needs:
