This model was trained on the best "bubble butt" images I could find.

35 training images @ 10,000 steps were used.

I couldn't find a similar lora for Flux Klein so I just made one myself. IMO, many of the bubble butt loras for other models give you a result that is cartoonishly large and unnatural. To me, bubble butt is not necessarily about the overall size, but about roundness and depth. You can have small hips and small thighs, but so long as the ass is very round with a lot of depth, that's a bubble butt. Obviously this is all subjective and simply one dude's opinion.

Seems to have trouble occasionally with aspect ratios other than 2:3. I plan to make improvements to it in the future. If you'd like to help me pay for runpod costs, feel free to leave a tip:
