This is an extract of my Humans model. It took a while to find the right balance of size and fidelity, but I am finally happy with this version. No trigger words, weight of 1 works well. Scale up from 0 - 1 to add more skin detail and "ordinary person" features. Visit the parent model for more information, but the short version is:

This model is designed to produce photo realistic images of normal people. Most SD models can only produce beautiful people. This is not that. You will get acne, moles, ratty hair, crooked teeth, wrinkles, and well, ordinary people

There are thousands of trigger words which can be found at https://gist.github.com/jaretburkett/cf8c224243834172fc13f72aaf49811d , or for a sorted list based on frequency, see here https://gist.github.com/jaretburkett/41370fdf69b791d2b406f3fa538d4b32 . The big one to know is the word “face”. A significant portion of the dataset has faces, and they were all tagged with face. Use it to get faces, without it you will get farther away shots, usually portraits.
