+# AWS Neuron
+
+🤗 Diffusers functionalities are available on [AWS Inf2 instances](https://aws.amazon.com/ec2/instance-types/inf2/), which are EC2 instances powered by [Neuron machine learning accelerators](https://aws.amazon.com/machine-learning/inferentia/). These instances aim at providing better compute performance(higher throughput, lower latency) with good cost-efficiency, which makes them good candidates for AWS users to deploy diffusion models for production.
+
+A wide range of features in 🤗 Diffusers are supported by [🤗 Optimum Neuron](https://huggingface.co/docs/optimum-neuron/en/index) via similar APIs. Once you have created an AWS Inf2 instance, you can install 🤗 Optimum Neuron:
+
+```bash
+python -m pip install --upgrade-strategy eager optimum[neuronx]
+```
+
+<Tip>
+
+We provide pre-built [Hugging Face Neuron Deep Learning AMI](https://aws.amazon.com/marketplace/pp/prodview-gr3e6yiscria2) (DLAMI) and Optimum Neuron containers for Amazon SageMaker. It's recommended to correctly set up your environment 
+
+</Tip>
+
+Here below is an example of generating images with Stable Diffusion XL model on an inf2.8xlarge instance (you can switch to cheaper inf2.xlarge instances once the model is compiled). We will use the `NeuronStableDiffusionXLPipeline` class, a class similar to the `StableDiffusionXLPipeline` class in diffusers to generate some images for fun.
+
+Unlike in 🤗 Diffusers, we need to compile models in the pipeline to Neuron compatible format `.neuron`. To do this, you will need to launch the following command:
+
+```bash
+optimum-cli export neuron --model stabilityai/stable-diffusion-xl-base-1.0 \
+  --batch_size 1 \
+  --height 1024 `# height in pixels of generated image, eg. 768, 1024` \
+  --width 1024 `# width in pixels of generated image, eg. 768, 1024` \
+  --num_images_per_prompt 1 `# number of images to generate per prompt, defaults to 1` \
+  --auto_cast matmul `# cast only matrix multiplication operations` \
+  --auto_cast_type bf16 `# cast operations from FP32 to BF16` \
+  sd_neuron_xl/
+```
+
+Now let's generate some images with pre-compiled SDXL models:
+
+```python
+>>> from optimum.neuron import NeuronStableDiffusionXLPipeline
+
+>>> stable_diffusion_xl = NeuronStableDiffusionXLPipeline.from_pretrained("sd_neuron_xl/")
+>>> prompt = "a pig with wings flying in floating US dollar banknotes in the air, skyscrapers behind, warm color palette, muted colors, detailed, 8k"
+>>> image = stable_diffusion_xl(prompt).images[0]
+```
+
