Our favorite grumpy tsundere they/them AI, Iris!
Iris turned out pretty well despite some technical issues getting the model to generate. Recommended tags are "ai, no nose, neck seam, pale blue skin, pale purple hair, purple eyes." My testing shows it tends to be a little more insist more upon their outfits and hairstyles that are in the strip/training data than some other models, so adjustment of tag strength for clothing and hair might be needed. Also also most of the data I had to work with involves Iris' normal grumpy expression, so getting other expressions might be a challenge too.
Comments and feedback are welcome, and I'll keep chipping away at models when I can!
