Qwen-Image-Edit-Outfit-2511-SFT
A full-parameter fine-tune of Qwen/Qwen-Image-Edit-2511 for garment / outfit virtual try-on (image editing): given a person photo and a garment photo, the model dresses the person in that outfit.
⚠️ Non-commercial, research use only. See LICENSE. This restriction is inherited from the training data (VITON-HD / IDM-VTON derivatives, CC BY-NC). Do not tag this model Apache-2.0 — the base is Apache-2.0, but the fine-tune carries the upstream NC constraint.
What changed from the base
Only the DiT (transformer) weights were updated via full-parameter SFT. All other components (text encoder, VAE, tokenizer, processor, scheduler) are unchanged from the base Qwen-Image-Edit-2511. So this directory loads exactly like the base model:
from diffusers import QwenImageEditPlusPipeline
import torch
pipe = QwenImageEditPlusPipeline.from_pretrained(
"lee31221/Qwen-Image-Edit-Outfit-2511-SFT", torch_dtype=torch.bfloat16
).to("cuda")

License
Non-Commercial Research Use only — see LICENSE and NOTICE.md. Commercial use is prohibited. This is stricter than the base model's Apache-2.0, because the fine-tune was trained on CC BY-NC derivatives.
Intended use & limitations
- Intended: academic research on image editing / virtual try-on.
- Not intended: any commercial product, service, or paid feature; generating non-consensual depictions of real people.
- Like all diffusion editors, outputs can be imperfect (garment detail drift, identity changes). Validate on a held-out test set before drawing conclusions.
