Lora (Flux) of a BBW model. Will need to use ComfyUI (not beginner friendly) or CivitAI (which are expensive).
V1: First go, works very well. You can't go wrong with this one.
V1.5: Potentially overfitted, but doesn't seem to be. So far, better quality outputs with a slight inconsistency. This version CAN generate slim/athletic outputs, so recommend including the words "curvy", or "voluptuous" in your (caption) prompt to calibrate.
