It's also technically a good thing: models are huge already (1.4 GB for stable diffusion models, 6 GB for SD XL, for example) and they would be a challenge to distribute if they had to incorporate a library of images.The model is a file that will help the generator toward the desired result. The generator starts by generating a random full noise image. Then, it will remove the noise in several steps. Of course, if the noise-removing was random, we would have a result that would be simply another random mess of pixels. That's why a model is used at this step, so that the denoising isn't random.The person operating the generator provides a "prompt", that's a text with keywords, that will guide the denoising process toward generating an image that will be (more or less, depending on the quality of the model) faithful to the prompt. It doesn't need to refer to the picture, only to the model, which contains (in layman's term, which I am) mathematical data that will guide the denoising process toward a given result. So by activating a few of those specifically, the denoising isn't random, it's guided by the word inputted in the prompt, leading to an image that should be acceptable by the viewer. It doesn't need images to refer to.It's also how you can you use the process to enhance/modify an image: you take an existing image, and you'll add a certain quantity of noise to it, and then run the denoising process. If it's too little noise, you'll get something that is close to the original image. If it's too much, you'll get a totally random image. In this case, I guess it took the dinosaur leg part of the image (for example) and prompted to say it should be dinosaur skin, and the generator added noise to the image, and denoised the dinosaur leg following the prompt, leading to a thing with the original shape of the dinosaur leg from the orginal image and the dinosaur-skin texture from denoising toward dinosaur-skin-texture, resulting in a mix from the original concept art and the AI intervention.If the artist criticized by WotC had worked on his own sketch, I wonder what would have been their reaction.</blockquote>
