 ---
+
+This is an NF4 quantized model of Qwen-image-edit-2511 so it can run on GPUs using less than 20GB VRAM. You can run it on lower VRAM like 16GB. 
+There were other NF4 models but they made the mistake of blindly quantizing all layers in the transformer. 
+This one does not. We retain some layers at full precision in order to ensure that we get quality output.
+
+You can use the original Qwen-Image-Edit parameters.
+
+
+Model tested: Working perfectly even with 10 steps.

+### sample code
+
+```python
+import os
+from PIL import Image
+import torch
+
+from diffusers import QwenImageEditPlusPipeline
+
+model_path = "ovedrive/Qwen-Image-Edit-2511-4bit"
+pipeline = QwenImageEditPlusPipeline.from_pretrained(model_path, torch_dtype=torch.bfloat16)
+print("pipeline loaded") # not true but whatever. do not move to cuda
+
+pipeline.set_progress_bar_config(disable=None)
+pipeline.enable_model_cpu_offload() #if you have enough VRAM replace this line with `pipeline.to("cuda")` which is 20GB VRAM
+image = Image.open("./example.png").convert("RGB")
+prompt = "Remove the lady head with white hair"
+inputs = {
+    "image": image,
+    "prompt": prompt,
+    "generator": torch.manual_seed(0),
+    "true_cfg_scale": 4.0,
+    "negative_prompt": " ",
+    "num_inference_steps": 20, # even 10 steps should be enough in many cases
+}
+
+with torch.inference_mode():
+  output = pipeline(**inputs)
+
+output_image = output.images[0]
+output_image.save("output_image_edit.png")
+print("image saved at", os.path.abspath("output_image_edit.png"))
