davinci-sdxl-lora-02

This is a LyCORIS adapter derived from stabilityai/stable-diffusion-xl-base-1.0.

The main validation prompt used during training was:

DaVinciXL, One mechanical device with gears and levers, no human subjects, one item in the image.

Validation settings

• CFG: 4.2
• CFG Rescale: 0.0
• Steps: 30
• Sampler: None
• Seed: 42
• Resolution: 1024x1024

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