Stable diffusion models for generating non-humans
Note that some of these model links might be NSFW. Login should be required for such content, but I cannot guarantee that all content available without it will be safe.
Model info
Some explanations about mode information:
- style - what is the model default style without changing it in prompt
- can upscale - whether the default upscaling works (tested at about 0.55 denoising strenght) reasonably well
- inpainting, outpainting - if the model can do inpainting or outpainting
- prompting type - which type of prompting to use (booru or normal)
- example - Grid of all girls in list at the time of creation (click for full size). Since making this is time consuming it might currently include fails that are not common or something that is easily remediated (out of frame typically). Also note that NSFW models style and quality might be affected by enforcing SFW images.
