langgraph-with-crewai

This repository contains detailed introduction to Langgraph, a new Langchain library. You will learn about langgraph and also create a miniproject using crewai and langgraph

🤔 How it works?

1. Get information from user and categorize it

Agent will take the user input and then categorize it based on the user query

2. Decides where to go using conditinal edge of langgraph

Agent uses langgraph to use the node based on the category of user query

3. Uses Langgraph nodes to integrate different workflows

Each workflow can be used as a subgraph or node which makes it easy to visualize and create any complex workflow which makes it multi-purpose agent.

⚒️ Architecture

Let’s take a look at the workflow of our agent!

We will first add the user input in our entry node where the user input will be categorized into 3 categories:

• email_query: If user want to generate an email response to given email
• weather_query: If user want weather information about any location
• other: If user want any other information

Now based on the categories, we will redirect the query to right node. 🔂

We will use CrewAI to create a crew which can categorize the email and then based on the category it will write a response. We will also create an separate agent for weather where we will provide the openweather function as a tool and it will automatically format the final weather information response. For all other queries, we will just make a simple OpenAI call.

Prerequisites

Here are the things you will need to create this project

• OpenAI API key
• Openweather API key
• A basic knowledge about CrewAI (If you don’t know about CrewAI then I suggest you to take a look at my blog about CrewAI)

How to run?

• Clone the repository
• Setup your environment variables

import os
os.environ['OPENAI_API_KEY'] = openai_secret
os.environ["OPENWEATHERMAP_API_KEY"] = openweather_secret

• Open any jupyter notebook from repository
• Select your existing python environment or create one using anaconda
• Run the code
