Ask HN: AI video models are good at nude body movement => porn in training data?

[sendos]

Are AI image and video generators trained with lots of porn images and video? They seem very capable of generating porn (even though they are filtered/moderated not to do so) with realistic physics and movement of nude body parts.

I assume this would not be something the models could have learned without porn being in the training data, is this correct?

gymnastics, shower ads, medical examination, there are lots of things infiltrated by AI that provide visual frames, no need for porn.

I don't think gymnastics, shower ads, or medical examinations show naked breasts bouncing, among other things. The models could learn how things might behave from observing clothed bodies, but I'm not sure that's realistic to expect from the models.
