From the video’s description:

AI is also used in some stages.

The AI ​​used is primarily Adobe Firefly, mainly for finishing touches, coloring assistance, and creating intermediate frames for the video.

The AI ​​is not entrusted with the entire production process; it is merely one tool to assist in expression.

I am not strongly opinionated on AI (whether “pro” or “anti” as some would put it). Even today, people (anime fans especially) have a really good eye for these things. Just as much as one can tell the difference between 3DCG, cel, digital ink/paint, or flash. In the end, consumers have standards and with the diverse selection of media, AI tends to be the one consumers will filter out of their view.
