I didn't quite understand the meaning of your question, but if you're asking if there are data models for AI artwork. When I run my daily stuff infinity query, I sometimes see AI content but nobody to date has been able to make an artwork that matches their concept, personally I tried to make a fusilier model to test but it takes too much time and if you don't put in a minimum of time and illustrations of the same concept from different angles, you end up with the creature from The Thing. For the latest tutorials I've seen, you apparently have to go through various AIs, first you have to manage to make a 360° animation from a model with at least one front and rear view (a priori from concept art plates), then output images from this 360° to have different angles of view, but it works better when the model is generic and not in a specific DA, when you have this library of angles of view then you can have a perfect model whit stable ai.
