Assuming you're talking about making a lora,You can make a character lora with 15 images. Something like 30 is my ideal number but it's by no means a strict rule. something that worked quite well in the past is to aim for a number of steps between 300 and 400 per epoch. So 16 images x 20 repeats = 320 steps per epoch. Then multiply your epochs to get around to 2000 steps. So 20 repeats, 7 epochs and 2240 total steps. Batch size of your choosing, you might wanna start with 1 and go from there. Resize all your images so the longest side is 1024. If you're training on a eps model, make sure to check the box for it and also "scale v-pred loss". 8/4 Dim/Alpha should be enough for a character lora. Not sure what you use for learning rate, might want to try Prodigy or something similar at a lr of 1.0. Keep Token of 1 if you want a trigger word. Save each epochs and do a xyz grid with prompt s/r to see which one is the closest. Then retrain the lora accordingly, more/less repeats/epochs/batch size/etc. Who's the character btw?
