It's apparently the other way around.
I gave Redpostit a once-over a while back. They did not exhibit the usual signs of "prompt-artists". Because they aren't one.
I didn't realise they do use AI tools though. It seems Redpostit draws lineart and coloring, then shades using AI. To me it's fairly obvius the image is further adjusted after that as well.
I'm unable to find a first-hand account of their workflow. I'm not sure what kind of model is being used.
I'll have to think about whether I will remove their work and disallow it in the future. But my first instinct is to compare this to what Joel Havier does for his animations.
Redpostit does not have a rate of output typical to AI "prompt-artists" and most of their work is consistent in terms of lineart and charachter style.
I am willing to believe they do in fact put in the majority of work in terms of creative labour.
I don't use "vibes" to tell.
Come back with something that proves it to be generative, or just voice your opinion that the no-AI rule should apply to assisted works as well.
