The fourth season of the Ascendance of a Bookworm anime, produced by WIT Studio, premiered on April 4 this year, though to an unexpectedly rocky start. The long-running series was faced with serious backlash after the reveal of the animated opening sequence, which viewers suspected featured AI-generated assets. In response to the criticism, WIT Studio posted an official announcement on April 10, in which it states that upon investigation into the opening’s production process, it confirmed that generative AI was involved.

Gankutsuou / Monte Cristo anime definitely uses it as a stylistic choice. It kinda gives it a stained glass look, where each “panel” has its own complex 2D pattern.
In general though it’s kinda a middle ground where you get characters who wear textured clothing more interesting than a single color without requiring a ton of time and effort to create. I can’t really bring myself to complain about it when it would take 10x the effort to make it look 1.5x as good (though I do appreciate it when they DO take the time and effort to make animated textured clothing)
I think it would be a bit more than 1.5x as good, but I don’t think 10x the effort is an exaggeration so it’s understandable.
