Different between Premium and Free

Need assistance and confirmation.
Does a premium gitlab user need to be in different platform of the free user?
Can free user be in the same platform as premium user?

Hi, at the minute as far as I am aware, it’s not possible from what I remember to mix/match users. There are posts on the forum relating to it. At the moment it seems an all or nothing. Either all the users are premium or all the users are free, no matter of whether they are owners, developers, maintainers or reviewer permissions.
