random

This is a standard PEFT LoRA derived from flux/unknown-model.

The main validation prompt used during training was:

A Simple Pencil sketch of Marilyn Monroe, showcasing her iconic smile and glamorous hairstyle. The shading captures the softness of her features and the elegance of her famous pose, framed by a hint of her signature wardrobe.

Validation settings

• CFG: 3.5
• CFG Rescale: 0.0
• Steps: 35
• Sampler: FlowMatchEulerDiscreteScheduler
• Seed: 42
• Resolution: 1024x1024
• Skip-layer guidance:

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

Inference

## Optional: quantise the model to save on vram.
## Note: The model was not quantised during training, so it is not necessary to quantise it during inference time.
