A: great questions! we are in the active process now to update the appsumo listing to reflect the new reality (credits, etc). that should be coming relatively soon, i'll defer to the listing updates to answer your credits question.

and yes, the primary difference (aside from credits) between tiers would be the number of licenses you are permitted to use. we are no longer gating on model access as it was previously.

there is an interface to manage licenses. the current setup is that the account holder (person who originally purchased access) will act as the primary user who is permitted to managing (creating/deleting) licenses and assign email addresses to specific licenses. the assignees are what we call "seat users" and will NOT have the ability to manage licenses but are able to inherit the properties of the primary account holder. the credits are in a shared pool across all seat users (this simplifies metering better).

is your desire to have seat users have the ability to manage licenses as well? please let me know
