bathroom_lora_1024

This is a standard PEFT LoRA derived from stabilityai/stable-diffusion-3.5-large.

The main validation prompt used during training was:

b8m home bathroom interior design. The bright and clean bathroom area. The walls are finished with white tiles, and the ceiling is also neatly finished with white paint. The floor is finished with white tiles in a herringbone pattern, further emphasizing the bright feel of the entire space. The main color is white, silver is used as a secondary color. White makes the space look wide and clean, silver adds a sleek modern touch.

Validation settings

• CFG: 4.0
• CFG Rescale: 0.0
• Steps: 50
• Sampler: FlowMatchEulerDiscreteScheduler
• Seed: 42
• Resolutions: 1024x1024, 1024x896, 1280x768
• Skip-layer guidance: skip_guidance_layers=[7, 8, 9],

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

## Optional: quantise the model to save on vram.
## Note: The model was quantised during training, and so it is recommended to do the same during inference time.
