# 🦜️🔗 LangChain 🤝 Amazon Web Services (AWS)
This repository provides LangChain components for various AWS services. It aims to replace and expand upon the existing LangChain AWS components found in the `langchain-community` package in the LangChain repository.
## Features
- **LLMs**: Includes LLM classes for AWS services like [Bedrock](https://aws.amazon.com/bedrock) and [SageMaker Endpoints](https://aws.amazon.com/sagemaker/deploy/), allowing you to leverage their language models within LangChain.
- **Retrievers**: Supports retrievers for services like [Amazon Kendra](https://aws.amazon.com/kendra/) and [KnowledgeBases for Amazon Bedrock](https://aws.amazon.com/bedrock/knowledge-bases/), enabling efficient retrieval of relevant information in your RAG applications.
- **Graphs**: Provides components for working with [AWS Neptune](https://aws.amazon.com/neptune/) graphs within LangChain.
- **Agents**: Includes Runnables to support [Amazon Bedrock Agents](https://aws.amazon.com/bedrock/agents/), allowing you to leverage Bedrock Agents within LangChain and LangGraph.
- **More to come**: This repository will continue to expand and offer additional components for various AWS services as development progresses.
**Note**: This repository will replace all AWS integrations currently present in the `langchain-community` package. Users are encouraged to migrate to this repository as soon as possible.
## Installation
You can install the `langchain-aws` package from PyPI.
```bash
pip install langchain-aws
```
## Usage
Here's a simple example of how to use the `langchain-aws` package.
```python
from langchain_aws import ChatBedrock
# Initialize the Bedrock chat model
llm = ChatBedrock(
model="anthropic.claude-3-sonnet-20240229-v1:0",
beta_use_converse_api=True
)
# Invoke the llm
response = llm.invoke("Hello! How are you today?")
print(response)
```
