Notes:

I don't know if it has an official name, though the ckpt file is called "anything v3.0 pruned".
Like NovelAI, it uses Stable Diffusion as a base to generate images.
After a few tests, I really feel like it gives overall better results than NovelAI, especially when trying to generate illustrations-like drawings.
The backgrounds are more detailed, the characters are more detailed, the poses are overall better.
Though it still suffers a lot from hand problems.
And what is great is that if it is better than NovelAI, that means that there's no need for anyone to pay for NovelAI anymore, unless they manage to make a better generator.
