Ai Influencers, and Models.

Hello, i am researching how to make Ai generated influencers, and i have been watching youtube videos and they basicaly say the same thing, they show you how to make Models with Fooocus and face swap them with the discord app. But i did not find them very good like https://www.instagram.com/fit_aitana/. I was wondering do any of you guys know how to make the best models and what is the best programs to use for images. Thank You in Advance!

fit_aitana is owned by an agency and they might have some proprietary tools to generate her images, considering the amount of revenue she brings in on monthly.
