BadYiffyMix Negative Embedding
This negative embedding is trained on YiffyMix to produce higher quality images on that model. Use the embedding, "badyiffymix"(or badyiffymix35, badyiffymix41 for the newer versions), in the negative prompt to see a general improvement in quality, vibrancy, and style.
badyiffymix v1.0 - generates images with a flatter, shaded style
badyiffymix35 - generates images with more detail and realism while retaining badyiffymix style and Yiffymix image composition
badyiffymix41 - generates images with a less saturation and heavy contrast compared to the original model while generally creating a slight improvement in detail
I modeled this embedding after great negative embeddings like boring_e621 or easynegative. I also made it to see what I could do with chilon249's negative prompt:
low res, lowres, blurry, bad anatomy, letterbox, deformity, mutilated, malformed, amputee, watermark, signature, unusual anatomy, username, sketch, monochrome
The newest version(badyiffymix41) doesn't use the above negative.
