What Exactly Is Qwen-Image-Edit?

Think of Qwen-Image-Edit as a bilingual photo assistant that understands both pictures and words. It is built on the 20-billion-parameter Qwen-Image model and adds two extra skills:

Installation in Three Commands

The pipeline is already packaged inside Hugging Face’s diffusers library.
Tested on Ubuntu 22.04 + Python 3.10; Windows and macOS work the same way.

# 1. Make sure you have CUDA 11.8+
nvidia-smi

# 2. Install the latest diffusers
pip install --upgrade "git+https://github.com/huggingface/diffusers"

# 3. No step three—the ModelScope loader will pull the 20 B model automatically.

Hardware note:

• GPU VRAM: at least 12 GB in FP16, 10 GB in BF16.
• No CPU mode: inference would be too slow for practical use.

Your First Edit: 5 Minutes From Zero to Image

Goal

Change a white rabbit to purple fur and add a flash-light background.

Files Needed

• rabbit.jpg (any RGB image)

Code

from PIL import Image
import torch
from modelscope import QwenImageEditPipeline

# Load once, reuse often
pipe = QwenImageEditPipeline.from_pretrained("Qwen/Qwen-Image-Edit")
pipe = pipe.to("cuda", torch.bfloat16)

# Load your image
image = Image.open("rabbit.jpg").convert("RGB")

# Describe the change in plain English
prompt = "Change the rabbit's color to purple, with a flash light background."

# Run
with torch.inference_mode():
    edited = pipe(
        image=image,
        prompt=prompt,
        true_cfg_scale=4.0,
        num_inference_steps=50,
        generator=torch.manual_seed(42)
    ).images[0]

edited.save("purple_rabbit.jpg")

Open purple_rabbit.jpg—only the rabbit and background have changed; the rest of the pixels are untouched.

Six Real-World Use Cases—Prompts Included

Below are exact prompts you can copy-paste. The left column links to the official demo so you can see the before-and-after.

Use Case	Source Image	Prompt	What Happens
1. Mascot Pose Swap		"Show the capybara in a thinking pose while keeping the character consistent"	Same character, new posture
2. MBTI Emoji Pack	Same as above	"INTJ version of the capybara, cool blue tone"	Generate 16 personality emojis from one base
3. 90° Object Rotation		"Rotate the camera 90° to display its side port"	You see the previously hidden side
4. Studio Ghibli Style		"Convert the portrait to Studio Ghibli style, soft pastel colors"	Photorealistic → hand-drawn anime
5. Add a Shop Sign		"Insert a wooden coffee shop sign on the blank wall"	Sign + realistic reflection
6. Fix Typos in Posters		"Replace 'Hello' with 'Hi', keep the same font"	New text, identical style

Pro Tips: Chain Editing Like a Designer

Sometimes one pass is not enough. The official calligraphy example shows how to iterate:

Step-by-Step Chain Edit

Why it works:

• Each edit is local, so VRAM stays low.
• You can review after every step instead of starting over.

Frequently Asked Questions

1. How is Qwen-Image-Edit different from Stable Diffusion?
   Stable Diffusion excels at generating images from scratch. Qwen-Image-Edit is tuned for editing existing images while keeping everything else identical.

2. Minimum VRAM?
   12 GB in FP16; 10 GB in BF16.

3. Commercial use allowed?
   Yes, Apache 2.0 license. Keep the license file in your distribution.

4. Does it understand Chinese prompts?
   Fully bilingual—Chinese and English work equally well.

5. Can I edit only a small region?
   Yes. Use bounding boxes as shown in the calligraphy example.

6. How to reproduce the same result?
   Pass generator=torch.manual_seed(your_number).

7. Best true_cfg_scale range?
   3–5. Below 3, changes are too weak; above 5, artifacts appear.

8. Batch processing?
   Wrap the pipeline call in a simple Python loop. Each image is processed independently.

9. CPU inference possible?
   Technically yes, but a single 512×512 edit can take minutes—impractical.

10. Watermark?
    None. The model outputs clean images.
