Trained for PonyXL with anime screencaps - thanks to https://fancaps.net/ - using kohya_ss. I would mostly recommend a weight of 0.85 to 1.
For specific traits/outfits use:
idol, puffy sleeves, puffy short sleeves, gradient dress, white dress, pink dress
bunny hair ornament, hair ornament
fangs, teeth
heart hands (however the probability to get good hands is not the best)
pregnant
Since this model is trained on screencaps I also deliberately train to replicate the anime style to get the character likeness as close as possible. If you want to apply a different style you can lower the weight (around 0.85 should be good for most).
What is Pony? It's one of the best SDXL checkpoints for anime (and more). It intrinsically understands a lot of styles, most characters and most importantly it will generate what you ask for with a much higher probability.
