This is not about any specific case. It's just a theoretical scenario that popped into my mind.

For context, in many places is required to label AI generated content as such, in other places is not required but it is considered good etiquette.

But imagine the following, an artist is going to make an image. Normal first step is search for references online, and then do the drawing taking reference from those. But this artists cannot found proper references online or maybe the artist want to experiment, and the artist decide to use a diffusion model to generate a bunch of AI images for reference. Then the artist procedes to draw the image taking the AI images as references.

The picture is 100% handmade, each line was manually drawn. But AI was used in the process of making this image. Should it have some kind of "AI warning label"?

What do you think?
