Koji aims to be a general purpose model with either a focus on sfw or nsfw. Model is finetuned/trained on hassaku with general to questionable images. Expect some exposed breasts or panty shots without corresponding negative prompts. Because it was trained on hassaku, it remains highly nsfw, with later iterations, it change more to sfw. Using the model:

Use mostly danbooru tags. No extra vae needed. For better promting on it, use this LINK or LINK. But instead of {}, use (), stable-diffusion-webui use (). Use "masterpiece" and "best quality" in positive, "worst quality" and "low quality" in negative.

My negative ones are: (low quality, worst quality:1.4) with extra monochrome, signature, text or logo when needed.

Use clip skip 2 with sampler DPM++ 2M Karras or DDIM.

Don't use face restore and underscores _, type red eyes and not red_eyes.
