+# OpenVINO Stable Diffusion 
+
+## hakurei/waifu-diffusion
+
+This repository contains the models from [hakurei/waifu-diffusion](https://huggingface.co/hakurei/waifu-diffusion) converted to
+OpenVINO, for accelerated inference on CPU or Intel GPU with OpenVINO's integration into Optimum:
+[optimum-intel](https://github.com/huggingface/optimum-intel#openvino). The model weights are stored with FP16
+precision, which reduces the size of the model by half.
+
+Please check out the [source model repository](https://huggingface.co/hakurei/waifu-diffusion) for more information about the model and its license.
+
+To install the requirements for this demo, do `pip install optimum[openvino]`. This installs all the necessary dependencies, 
+including Transformers and OpenVINO. For more detailed steps, please see this [installation guide](https://github.com/helena-intel/optimum-intel/wiki/OpenVINO-Integration-Installation-Guide).
+
+The simplest way to generate an image with stable diffusion takes only two lines of code, as shown below. The first line downloads the 
+model from the Hugging Face hub (if it has not been downloaded before) and loads it; the second line generates an image.
+
+```python
+from optimum.intel.openvino import OVStableDiffusionPipeline
+
+stable_diffusion = OVStableDiffusionPipeline.from_pretrained("hakurei/waifu-diffusion")
+images = stable_diffusion("a random image").images
+```
+
+The following example code uses static shapes for even faster inference. Using larger image sizes will
+require more memory and take longer to generate.
+
+If you have an 11th generation or later Intel Core processor, you can use the integrated GPU for inference, and if you have an Intel 
+discrete GPU, you can use that. Add the line `stable_diffusion.to("GPU")` before `stable_diffusion.compile()` in the example below. 
+Model loading will take some time the first time, but will be faster after that, because the model will be cached. On GPU, for stable
+diffusion only static shapes are supported at the moment.
+
+
+```python
+from optimum.intel.openvino.modeling_diffusion import OVStableDiffusionPipeline
+
+batch_size = 1
+num_images_per_prompt = 1
+height = 256
+width = 256
+
+# load the model and reshape to static shapes for faster inference
+model_id = "hakurei/waifu-diffusion"
+stable_diffusion = OVStableDiffusionPipeline.from_pretrained(model_id, compile=False)
+stable_diffusion.reshape( batch_size=batch_size, height=height, width=width, num_images_per_prompt=num_images_per_prompt)
+stable_diffusion.compile()
+
+# generate image!
+prompt = "a random image"
+images = stable_diffusion(prompt, height=height, width=width, num_images_per_prompt=num_images_per_prompt).images
+images[0].save("result.png")
+```
