LangGraph Serving with BentoML

This repo demonstrates how to serve LangGraph agent application with BentoML.

See here for a full list of BentoML example projects.

Overview

• AI Agent Serving: Serving LangGraph Agent as REST API for easy integration
• Flexible Invocation: Supports both synchronous and asynchronous (queue-based) interactions.
• Deployment Options: Run locally or deploy to BentoCloud for scalability.
• LLM Deployment: Use external LLM APIs or deploy open-source LLM together with the Agent API service

This project serves as a reference implementation designed to be hackable, providing a foundation for building and customizing your own AI agent solutions.

Getting Started

Download source code:

git clone https://github.com/bentoml/BentoLangGraph.git
cd BentoLangGraph/

Follow the step-by-step guide for serving & deploying LangGraph agents with BentoML:

• Anthropic Claude 3.5 Sonnet
• Mistral 7B Instruct

Troubleshoot

When running the example code which uses DuckDuckGo search tool, you may run into the following rate limit error:

RatelimitException('https://duckduckgo.com/ 202 Ratelimit')

You may use a different tool from LangChain's pre-built tools list here or create a custom tool.

For example, you can use exa to replace DuckDuckGo for search:

- from langchain_community.tools import DuckDuckGoSearchRun
- tools = [search]
+ from exa_search import retrieve_web_content
+ tools = [retrieve_web_content]
