Description

COURSE WAS RE-RECORDED and supports- LangChain Version 0.37+

**Ideal students are software developers / data scientists / AI/ML Engineers**

Welcome to the AI Agents with LangChain and LangGraph Udemy course - Unleashing the Power of Agentic AI!

This  course is designed to teach you how to QUICKLY harness the power the LangChain & LangGraph libraries for LLM applications and Agentic AI.

This course will equip you with the skills and knowledge necessary to develop cutting-edge LLM solutions for a diverse range of topics.

Please note that this is not a course for beginners. This course assumes that you have a background in software engineering and are proficient in Python. I will be using Pycharm IDE but you can use any editor you'd like since we only use basic feature of the IDE like debugging and running scripts .

What You’ll Build:  No fluff. No toy examples. You’ll build:

Search Agent

Documentation Helper – A chatbot over Python package docs (and any data you choose), using advanced retrieval and RAG.

Slim ChatGPT Code Interpreter – A lightweight code execution assistant.

Prompt Engineering Theory Section

Introduction to LangGraph

Introduction to Model Context Protocol (MCP)

Ice Breaker Agent – An AI agent that searches Google, finds LinkedIn and Twitter profiles, scrapes public info, and generates personalized icebreakers.

DISCLAIMERS

Please note that this is not a course for beginners. This course assumes that you have a background in software engineering and are proficient in Python.

The Ice-Breaker (Optional) project requires usage of 3rd party APIs-

Scrapin, Tavily, Twitter API  which are generally paid services.

All of those 3rd parties have a free tier we will use to create stub responses development and testing.
