A question that I really want to know

Does anyone know what AI software is used to make those arknights endfield gugugaga endministrator or any AI chibi videos? I honestly like them and I want to know how do you make them like what program is used.

By the way, those videos that have her unfortunately 💀 in pretty messed up ways I made a few that have an alternate ending on Sora.ai And I want to make it on the other program that is used
