This is a download site for the negative embedding boring_e621. Its original huggingface repository, which goes into more detail about how it was trained and what it does, can be found here.
Briefly, This embedding attempts to capture what it means for an image to be uninteresting. So if you're using the Automatic1111 Stable Diffusion WebUI, you can place this file in stable-diffusion-webui\embeddings and add the trigger word to your NEGATIVE prompt, and your results should become more interesting, both stylistically and topically.
The title image for this model illustrates the quality improvements it can make to four simple prompts in the base SD 1.5 model. In the first column, for example, boring_e621_v4 makes the hamburger more photorealistic, places it on a cocobolo table, freshens the vegetables, and adds a slice of cheese and an order of fries.
As this embedding is known for its ability to improve furry art specifically, the second image illustrates the improvements it yields on four simple prompts on YE-18, a model appearing in many furry mix models.
Which version should I get?
boring_e621_v4 (newest and works best with most models)
boring_e621 (works well with most models, but is less intense than v4)
boring_e621_fluffyrock_v4 (should only be used with a Fluffyrock model WITHOUT "vpred" in the name)
Each of the Suggested Resource models below has specifically been reported to produce great results with boring_e621 (except for Fluffyrock, which has been reported to work well with boring_e621_fluffyrock_v4 instead).
