This LoRA primarily enhances aesthetics and details. It is the result of a reinforcement learning (RL) experiment with a custom reward model, that went surprisingly well so I'm releasing it as a prototype. Trained on preview3. Paired images are base (left) vs LoRA (right).
Use at weight 1 by default. Adjust weight up or down according to your preferences. Might need to raise the weight a bit above 1 when used with other checkpoints (it gets weakened when applied to a strong aesthetics finetune).
