AI art is still in its infancy but its really fun to experiment with. There are so many models and samplers that you can use to generate different creations. It's almost limitless but realistically, its very unlikely for you to experience every single ever generated with the models currently available.
There are too many models to choose from. Some may generate realistic images, some may be more 'plastic' than others, and there are those that focus more on drawings and outlines.
Personally, I like messing around with chibi's and paintings.
