simpletuner-lora-schnell

This is a LyCORIS adapter derived from black-forest-labs/FLUX.1-schnell.

The main validation prompt used during training was:

A photo-realistic portrait of sks123man

Validation settings

• CFG: 1.0
• CFG Rescale: 0.0
• Steps: 4
• Sampler: None
• Seed: 42
• Resolution: 1024x1024

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

You can find some example images in the following gallery:
