> Is there a way to have current AI tools maintain consistency when generating multiple images of a specific creature or object?
...but, all of these can't maintain consistency.
All they can do is generate the same 'concept'. For example, 'pictures of batman' will always generate pictures that are recognizably batman.
However, good luck generating comic cells; there is nothing (that I'm aware of) that will let you generate consistency across images; every cell will have a subtly different batman, with a different background, different props, different lighting, etc.
The image-to-image (and depth-to-image) pipelines will let you generate structurally consistent outputs (eg. here is a bed, here is a building), but they will still be completely distinct in detail, and lack consistency.
This is why all animations using this tech have that 'hand drawn jitter' to them, because it's basically not possible (currently) to say: "an image of batman in a new pose, but that is like this previous frame".
So... to the OP's question:
Recognizable outputs? Yes sure, you've already been able to generate 'a picture of a dog'.
New outputs? Yeah! You can train it for something like 'a picture of 'Renata Glasc the Chem-Baroness' now.
Consistency across outputs? No, not really. Not at all.
