This is a model of the character Zhong Kunyi from the Chinese series "Men with Swords" (刺客列传).
It was trained on Dreambooth using about 60 pictures. Simply include "photo of zky zhong kunyi" on your text prompt to get an image. Sometimes, it is good to include "long hair" in the positive prompt and "Female" and related tags in the negative prompts, as SD is very biased towards generating women.
It is a good idea to generate a couple of images and reuse the seeds you liked the most.
Beware that this model will produce NSFW results if asked so.
