simpletuner-lora-spindrift

This is a standard PEFT LoRA derived from black-forest-labs/FLUX.1-dev.

The main validation prompt used during training was:

photo of a modern architectural interior event space at dusk

Validation settings

• CFG: 3.0
• CFG Rescale: 0.0
• Steps: 25
• Sampler: None
• Seed: 42
• Resolution: 1216x832

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

You can find some example images in the following gallery:
