lora-training

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

The main validation prompt used during training was:

A simple, clean line drawing of a right-angled triangle. The right angle is at the bottom left corner. The base is labeled as '6 cm' and the height is labeled as '4 cm'. The drawing is set against a plain white background.

Validation settings

CFG: 3.5
CFG Rescale: 0.0
Steps: 24
Sampler: None
Seed: 42
Resolution: 512

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