For significantly less compute you could make pretty good coloring book pages just using different edge detection methods or simply using the stamp filter in Photoshop.

I wouldn't call simple edge detection "pretty good" colouring book generation. You're just gonna get all the edges of complex shapes; it needs to be cartoonified/simplified with having large contiguous patches of colour in mind.

Tangentially related, I want to make a comic strip. I have some questions for people knowledgeable in "prompt engineering": 1. What's the style name for dilbert-like comic strips? Comic? Line art? 2. How do I produce consistent characters throughout the "comic box" and episodes? 3. How do I hint the generation of the comic? E.g. I draw a stick figure of someone sitting, and it generates my character with that pose. 4…

2. How do I produce consistent characters throughout the "comic box" and episodes?: controlnet "reference"

3. How do I hint the generation of the comic? E.g. I draw a stick figure of someone sitting, and it generates my character with that pose: controlnet "open pose/sketching"

4. How do I "refine" some parts of the generated image. For example I like the generated character, but I want the face to look different direction: inpainting

It's still basically impossible to get perfectly consistent character features across multiple images/without a massive amount of effort. These models have been trained to generate single/standalone images.

Maybe some of the Sora related tech (where it generates frames in parallel/each frame has the context of every other frame) for coherency can be used to improve the plain image generation stuff as well, ie being able to specify a character with multiple views (3/4, back, front etc) so that you can refer to that character in your prompt.

Earlier quoted context omitted.

The artistic license thing in itself I think is fine if only it didn't go just one direction. And you may very well be right that the examples it may have seen of coloring books may well be a very peculiar subset.

“Artistic license” assumes agency, that there is some artist who understands the facts of a situation and deliberately changes them in the work. It does not apply to a machine doing a poor job because it lacks context in its training data. Just like medieval art, which was inaccurate¹ due to ignorance , not because the person doing the drawing decided to add some flare. ¹ https://www.youtube.com/watch?v=jnB2Uj7gWSE

There's a site showing how Europeans drew elephants from popular descriptions once they disappeared from the continent: https://www.uliwestphal.de/elephas-anthropogenus/index.html
