Introduction

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.

CDK Versions

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.

Design guidelines and Development guide

If you want to add a new construct to the library, check out our design guidelines, then follow the development guide

Getting Started

For TypeScript

• 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';

For Python

• 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

For NuGet

• Create or use an existing CDK application in Python

  • cdk init app --language csharp

• Install the package while in the Visual Studio project:

  • dotnet add package CdkLabs.GenerativeAICdkConstructs

• Use the namespace:

  • using Cdklabs.GenerativeAiCdkConstructs;

For Go

• Create or use an existing CDK application in Python

  • cdk init app --language go

• Get the module:

  • go get github.com/cdklabs/generative-ai-cdk-constructs-go/generative-ai-cdk-constructs

• Import the library:

  • import "github.com/cdklabs/generative-ai-cdk-constructs-go/generative-ai-cdk-constructs"

NOTE: The Go distribution repository, distributes the JSII tar gzipped versioned source from the source repository

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.

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

Sample Use Cases

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".
