sd3-lora-training-rank64-v4

This is a standard PEFT LoRA derived from stabilityai/stable-diffusion-3-medium-diffusers.

The main validation prompt used during training was:

A design of a cute pokemon, featuring a single bird, water type pokemon, on a white background, style of Sugimori Kenji Vector Art

Validation settings

CFG: 5.0
CFG Rescale: 0.0
Steps: 20
Sampler: None
Seed: 42
Resolution: 1024x1024

Note: The validation settings are not necessarily the same as the training settings.
