  • Implement chain-of-thought prompting for complex problem-solving

  • Build self-correction loops where agents validate and improve their own responses

  • Design agentic workflows using LangGraph with state machines and conditional routing

  • Run large language models locally using Ollama (llama3.2) with complete privacy

  • Create interactive chat interfaces with Streamlit for production-ready applications

  • Implement semantic search and vector embeddings for intelligent memory retrieval

  • Build autonomous agents that choose tools, plan actions, and execute tasks independently

  • Customize agent personality and behavior through advanced prompt engineering

Course Description

Stop paying for expensive AI APIs. Start building your own intelligent agents.

This comprehensive course teaches you how to build agentic AI systems from the ground up using modern open-source technologies. Unlike simple chatbots, agentic AI can reason, plan, use tools, remember conversations, and make autonomous decisions—all running locally on your machine with zero API costs.


What Makes This Course Different?

- 100% Open Source - No proprietary APIs, no vendor lock-in, no recurring costs

- Complete Source Code Included - Every lecture comes with fully working code you can download and customize

- Hands-On Practice Exercises - Carefully designed exercises that enhance your skills and add powerful features to your agent Production-Ready Skills - Build real applications, not toy examples.

- Local Development - Everything runs on your laptop with full data privacy

- Modern AI Stack - Learn the tools used by professional AI engineers today


What You'll Build

By the end of this course, you'll have created a fully functional agentic AI application with these capabilities:

- Web Search Integration - Agent searches DuckDuckGo for current information automatically

- Document Analysis - Upload PDFs or text files and ask questions about their content

- Persistent Memory - Conversations are remembered across sessions using vector database technology

- Intelligent Decision Making - Agent decides when to search, when to analyze files, or when to use existing knowledge 

- Self-Correction - Validates its own answers and refines them if needed

- Autonomous Planning - Uses the ReAct pattern to reason before taking action

- State Management - Built with LangGraph for complex multi-step workflows

- User Sessions - Multiple users can have separate conversations with persistent history

- Customizable Personality - Change agent behavior through prompt engineering

i want to learn more on this...

By Gaurav Rana on 3/3/2026

Do we have to memorize this complex code since I'm a beginner but have an idea about what a function does as well as about modules of Python, but this code really scares me!

By Jack Ilmonen on 2/26/2026

It seems very clear and easy to follow! awesome!
