Qwen-Image-Edit-2511 LoRA - Character References -> Scene

Turns one or more character reference images (neutral pose, plain light-gray background, eye-level) into a full illustrated scene with those characters, preserving identity and art style. Trained with DiffSynth-Studio on 179 reference->scene pairs (stylized Western digital art).

Prompt format (same as training): Using the character(s) from Image 1, create a full illustrated scene: <scene description> Multiple separate references are supported: ...from Image 1 and ... from Image 2...

Usage

python

import torch
from PIL import Image
from diffsynth.pipelines.qwen_image import QwenImagePipeline, ModelConfig

pipe = QwenImagePipeline.from_pretrained(
    torch_dtype=torch.bfloat16, device="cuda",

        ModelConfig(model_id="Qwen/Qwen-Image", origin_file_pattern="vae/diffusion_pytorch_model.safetensors"),
    ],
    tokenizer_config=None,
    processor_config=ModelConfig(model_id="Qwen/Qwen-Image-Edit", origin_file_pattern="processor/"),
)
pipe.load_lora(pipe.dit, "checkpoints/epoch-4.safetensors")
ref = Image.open("reference.jpeg")
img = pipe("Using the character from Image 1, create a full illustrated scene: ...",
           edit_image=[ref], seed=0, num_inference_steps=40,
           height=1328, width=1024, zero_cond_t=True)  # zero_cond_t is REQUIRED for 2511
