The AWS Generative AI Constructs Library is an open-source extension of the AWS Cloud Development Kit (AWS CDK) that provides multi-service, well-architected patterns for quickly defining solutions in code to create predictable and repeatable infrastructure, called constructs. The goal of AWS Generative AI CDK Constructs is to help developers build generative AI solutions using pattern-based definitions for their architecture.
The patterns defined in AWS Generative AI CDK Constructs are high level, multi-service abstractions of AWS CDK constructs that have default configurations based on well-architected best practices. The library is organized into logical modules using object-oriented techniques to create each architectural pattern model.
AWS Generative AI CDK Constructs and the AWS CDK are independent teams and have different release schedules. Each release of AWS Generative AI CDK Constructs is built against a specific version of the AWS CDK. The CHANGELOG.md file lists the CDK version associated with each AWS Generative AI Constructs release. For instance, AWS Generative AI CDK Constructs v0.0.0 was built against AWS CDK v2.96.2. This means that to use AWS Generative AI CDK Constructs v0.0.0, your application must include AWS CDK v2.96.2 or later. You can continue to use the latest AWS CDK versions and upgrade the your AWS Generative AI CDK Constructs version when new releases become available.
Contributions of all kinds are welcome! Check out our contributor guide
If you want to add a new construct to the library, check out our design guidelines, then follow the development guide
- Create or use an existing CDK application in TypeScript.
cdk init app --language typescript
- Run
npm install @cdklabs/generative-ai-cdk-constructs - The package should be added to your package.json.
- Import the library:
import * as genai from '@cdklabs/generative-ai-cdk-constructs';
- Create or use an existing CDK application in Python
cdk init app --language python
- Install the package:
pip install cdklabs.generative-ai-cdk-constructs
- Import the library:
import cdklabs.generative_ai_cdk_constructs
Refer to the documentation for additional guidance on a particular construct: Catalog
The following constructs are available in the library:
L3 constructs

| Question answering | Utilizing Large Language Models (Anthropic Claude V2.1.) for Question Answering on PDF documents with RAG (retrieval augmented generation) source and/or long context. Additionally, leveraging Anthropic Claude 3 for visual question answering on images. | Amazon OpenSearch, AWS Lambda, Amazon Bedrock, AWS AppSync |
| Summarization | Document summarization with a large language model (Anthropic Claude V2.1). | AWS Lambda, Amazon Bedrock, AWS AppSync and Amazon ElastiCache for Redis. |

| Content Generation | Generate images from text using Amazon titan-image-generator-v1 or stability.stable-diffusion-xl model. | AWS Lambda, Amazon Bedrock, AWS AppSync |
L2 Constructs
| Construct | Description | AWS Services used |
|---|---|---|
| Lambda layer | Python Lambda layer providing dependencies and utilities to develop generative AI applications on AWS. | AWS Lambda, Amazon Bedrock, Amazon SageMaker |
| Amazon Bedrock | CDK L2 Constructs for Amazon Bedrock. | Amazon Bedrock, Amazon OpenSearch Serverless, AWS Lambda |
| Amazon OpenSearch Serverless Vector Collection | CDK L2 Constructs to create a vector collection. | Amazon OpenSearch Vector Index |

The official samples repository https://github.com/aws-samples/generative-ai-cdk-constructs-samples includes a collection of functional use case implementations to demonstrate the usage of AWS Generative AI CDK Constructs. These can be used in the same way as architectural patterns, and can be conceptualized as an additional "higher-level" abstraction of those patterns. Those patterns (constructs) are composed together into stacks, forming a "CDK app".

Provided CDK constructs collect anonymous operational metrics to help AWS improve the quality and features of the constructs. Data collection is subject to the AWS Privacy Policy (https://aws.amazon.com/privacy/). To opt out of this feature, simply disable it by setting the construct property "enableOperationalMetric" to false for each construct used. Defaults to true.
Roadmap is available through the GitHub Project
You should consider doing your own independent assessment before using the content in this library for production purposes. This may include (amongst other things) testing, securing, and optimizing the CDK constructs and other content, provided in this library, based on your specific quality control practices and standards.
