PBSAS-4

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

The main validation prompt used during training was:

PBSAS, a man is eating a donut

Validation settings

• CFG: 3.5
• CFG Rescale: 0.0
• Steps: 15
• Sampler: None
• Seed: 42
• Resolution: 1024

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