+### Stable Diffusion XL Reference
+[Stable Diffusion XL Reference](https://github.com/Mikubill/sd-webui-controlnet#reference-only-control) 是一种基于stable diffusion xl不需要任何控制模型就可以直接使用图像作为参考来引导生成图像的方法。它使用方式如下所示：
+
+```python
+import paddle
+from PIL import Image
+from ppdiffusers.utils import load_image
+from pipline_stable_diffusion_xl_reference import StableDiffusionXLReferencePipeline
+from ppdiffusers.schedulers import UniPCMultistepScheduler
+
+input_image = load_image("https://github.com/PaddlePaddle/PaddleMIX/assets/68105073/9c8e5c53-dc9a-46bb-9504-3d75a7c22ed2")
+
+pipe = StableDiffusionXLReferencePipeline.from_pretrained(
+    "stabilityai/stable-diffusion-xl-base-1.0",
+    use_safetensors=True,
+    variant="fp16")
+
+pipe.scheduler = UniPCMultistepScheduler.from_config(pipe.scheduler.config)
+
+result_img = pipe(ref_image=input_image,
+      prompt="a dog running on grassland, best quality",
+      num_inference_steps=20,
+      reference_attn=True,
+      reference_adain=False).images[0]
+
+result_img.save("output.png")
+```
