Solution overview

With SageMaker JumpStart, you can choose from a broad selection of publicly available foundation models (FMs). ML practitioners can deploy FMs to dedicated SageMaker instances from a network isolated environment and customize models using Amazon SageMaker for model training and deployment. You can now discover and deploy the Stable Diffusion 3.5 large model with a few clicks in SageMaker Studio or programmatically through the SageMaker Python SDK, enabling you to derive model performance and MLOps controls with SageMaker features such as Amazon SageMaker Pipelines, Amazon SageMaker Debugger, or container logs. The model is deployed in an AWS secure environment and under your virtual private cloud (VPC) controls, helping provide data security.

The Stable Diffusion 3.5 Large model is available today in the following AWS Regions: US East (N. Virginia, Ohio), US West (Oregon), Asia Pacific (Osaka, Hong Kong), China (Beijing), Middle East (Bahrain), Africa (Cape Town), and Europe (Milan, Stockholm).

SageMaker Studio is an integrated development environment (IDE) that provides a single web-based visual interface where you can access purpose-built tools to perform all machine learning (ML) development steps, from preparing data to building, training, and deploying your ML models. For more details on how to get started and set up SageMaker Studio, refer to Amazon SageMaker Studio.

Prerequisites

Make sure that your AWS Identity and Access Management (IAM) role has AmazonSageMakerFullAccess. To successfully deploy the model, confirm that your IAM role has the following three permissions and you have authority to make AWS Marketplace subscriptions in the AWS account used:

aws-marketplace:ViewSubscriptions aws-marketplace:Unsubscribe aws-marketplace:Subscribe

Subscribe to the Stable Diffusion 3.5 Large model package

You can access SageMaker JumpStart through the SageMaker Studio Home page by selecting JumpStart in the Prebuilt and automated solutions section. The JumpStart landing page allows you to explore various resources including solutions, models, and notebooks. You can search for a particular provider. In this following screenshot, we are looking at all the models by Stability AI on SageMaker JumpStart.

Each model is presented with a model card containing key information such as the model name, fine-tuning capability, provider, and a brief description. To find the Stable Diffusion 3.5L model, you can either browse the Foundation Model: Image Generation carousel or use the search function. Select Stable Diffusion 3.5 Large.

Next, we will subscribe to Stable Diffusion 3.5 Large, follow these steps:

Open the model listing page in AWS Marketplace using the link available from the example notebook in SageMaker JumpStart. On the listing, choose Continue to subscribe. On the Subscribe to this software page, review and choose Accept Offer if you and your organization accept the EULA, pricing, and support terms. Choose Continue to configuration to start configuring your model. Choose a supported Region, and you will see the model package Amazon Resource Name (ARN) that you need to specify when creating an endpoint.

Note: If you don’t have the necessary permissions to view or subscribe to the model, reach out to your AWS administrator or procurement point of contact. Many enterprises may limit AWS Marketplace permissions to control the actions that someone can take in the AWS Marketplace Management Portal.

Deploy the model in SageMaker Studio

Now you’re prepared to follow the notebook example from Stability AI’s GitHub repository to create an endpoint (with the model package ARN from AWS Marketplace) and create a deployable ModelPackage.

For Stable Diffusion 3.5 Large, you’ll need to deploy on an Amazon Elastic Compute Cloud (Amazon EC2) ml.p5.48xlarge instance.

Generate images with a text prompt

Refer to the Stable Diffusion 3.5 Large documentation for more details. From the example notebook, the code to generate an image is as follows:

sm_runtime = boto3.client("sagemaker-runtime")params = {    "prompt": " Photography, pink rose flowers in the twilight, glowing, tile houses in the background.",    "seed": 101,    "aspect_ratio": "21:9",    "output_format": "jpeg",}payload = json.dumps(params).encode("utf-8")response = sm_runtime.invoke_endpoint(    EndpointName=endpoint_name,    ContentType="application/json",    Accept="application/json",    Body=payload,)out = json.loads(response["Body"].read().decode("utf-8"))try:    base64_string = out["body"]["images"][0]    image_data = base64.b64decode(base64_string)    image = Image.open(io.BytesIO(image_data))    display(image)except:    print(out)

The following are examples of images generated from different prompts.

Prompt: Photography, pink rose flowers in the twilight, glowing, tile houses in the background.	Prompt: The word “AWS x Stability” in a thick, blocky script surrounded by roots and vines against a solid white background. The scene is lit by flat light, creating a reflective scene with a minimal color palette. Quilling style.	Prompt: Expressionist painting, side profile of a silhouette of a student seated at a desk, absorbed in reading a book. Her thoughts artistically connect to the stars and the vast universe, symbolizing the expansion of knowledge and a boundless mind.

Prompt: High-energy street scene in a neon-lit Tokyo alley at night, where steam rises from food carts, and colorful neon signs illuminate the rain-slicked pavement.	Prompt: 3D animation scene of an adventurer traveling the world with his pet dog.

Clean up

When you’ve finished working, you can delete the endpoint to release the EC2 instances associated with it and stop billing.

Get your list of SageMaker endpoints using the AWS Command Line Interface (AWS CLI) as follows:

!aws sagemaker list-endpoints

Then delete the endpoints:

deployed_model.sagemaker_session.delete_endpoint(endpoint_name)
