Welcome to the world of Stochastic! If you’re looking to accelerate your image generation using the Stable Diffusion model, you’ve come to the right place. In this article, we’ll explore how to deploy the model efficiently and achieve rapid inference times. Let’s dive in!

Installation

Before we get into the nitty-gritty, you need to prepare your system.

Quickstart

• Ensure that you have Python and Docker installed on your machine.
• Install the latest version of the StochasticX library:

pip install stochasticx

• Deploy the Stable Diffusion models using the command:

stochasticx stable-diffusion deploy --type aitemplate

If you don’t have a Stochastic account, worry not! The CLI will prompt you to create one quickly. It’s free and takes just a minute. Sign up →

• To perform inference with the deployed model, use the command:

stochasticx stable-diffusion inference --prompt "Riding a horse"

• To view the deployment logs, execute:

stochasticx stable-diffusion logs

• Finally, to stop and remove the deployment, use this command:

stochasticx stable-diffusion stop

How to Get Less Than 1s Latency?

If you want your image to be generated in under a second, here’s the trick:

max_seq_length: 64, num_inference_steps: 30, image_size: (512, 512)

By changing the num_inference_steps to 30, you can achieve a staggering image generation time of just 0.88 seconds! You can also experiment with reducing the image_size to see how it affects performance.

How to Run on Google Colab?

If you’re more comfortable using Google Colab, we have some great resources for you:

• Try PyTorch – FP16 in Colab
• Try TensorRT in Colab

Within these notebooks, you can test the full flow and inference on a T4 GPU.

Optimizations & Benchmarks

To ensure optimal performance, consider the following optimizations:

• AITemplate: Latest optimization framework of Meta
• TensorRT: NVIDIA TensorRT framework
• nvFuser: nvFuser with PyTorch
• FlashAttention: FlashAttention integration in Xformers

Sample Images Generated

Here are a few examples of images generated using the model:

• Super Mario learning to fly in an airport

• The Easter bunny riding a motorcycle in New York City

Troubleshooting

If you encounter any issues during installation or deployment, here are some tips:

• Ensure your Docker is up and running properly before deploying the model.
• If you experience lag, check if other applications are consuming too much GPU memory.
• Make sure your Python version is compatible with the libraries being installed.
• For any unexpected errors during inference, review the error logs using the command:

stochasticx stable-diffusion logs
