Hi Kjun, I am very interested in this feature “Add an AI-based automatic Zoi face generation feature”. I am hoping by this you mean that we can create/scan photos of ourselves or our favourite celebrities/characters then export their 3D head meshes into Inzoi CAZ for further editing! 
It has always been my dream to be able to bring the characters I created in Sims 4 and a few of my favourite celebrities into Inzoi!! There is another way I can suggest to bring our own customized characters into Inzoi, but I am going to post that in Wishlist. All in all, you are also welcome to invent various ways other than my suggestion to do this, as long as players are able to bring their own customized characters into Inzoi.
Thank you so much for reading this post, Kjun!
