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

The main validation prompt used during training was:

home-interior. two brown chairs and a coffee table. A framed abstract artwork hangs above the armchairs. The walls are painted in a soft neutral tone, and a large flat-screen TV is mounted on wall. A rug covers part of the light oak flooring. On the left, large black-framed glass sliding doors lead to outdoor.

Validation settings

• CFG: 3.0
• CFG Rescale: 0.0
• Steps: 25
• 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.

The text encoder was not trained. You may reuse the base model text encoder for inference.

Inference

import torch
from diffusers import DiffusionPipeline

model_id = 'stabilityai/stable-diffusion-3.5-large'
adapter_id = 'daehuncho/porcelain'
pipeline = DiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.bfloat16) # loading directly in bf16
pipeline.load_lora_weights(adapter_id)

prompt = "home-interior. two brown chairs and a coffee table. A framed abstract artwork hangs above the armchairs. The walls are painted in a soft neutral tone, and a large flat-screen TV is mounted on wall. A rug covers part of the light oak flooring. On the left, large black-framed glass sliding doors lead to outdoor."
negative_prompt = 'blurry, cropped, ugly'

## 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.
