Pony Diffusion V4

https://civitai.com/models/20064/pony-diffusion

Pony Diffusion is a Stable Diffusion model that has been fine-tuned on high-quality pony, furry and other non photorealistic SFW and NSFW images.

This model is capable of producing SFW and NSFW content so it's recommended to use 'safe' prompt in combination with negative prompt for features you may want to suppress (i.e. nudity) if you want to avoid NSFW outputs.

Despite its name, this model is capable of producing wide range of furry and cartoon images as side effect of improving data diversity (with exception of anime styles, for which Waifu Diffusion is much stronger choice).
