Build a Deep AI Agent from Scratch (Beginner-Friendly | LangChain + Groq) | Tamil | Karthik's Show

In this video, we build a Deep AI Agent from scratch using LangChain and Groq’s free API — completely beginner-friendly and step-by-step in Tamil. If you've heard about Deep Agents but felt confused about how they actually work, this video will make it simple. Link to GitHub project: https://github.com/KarthiksShow/Deep-Agent Link to Deep Agent Explainer vide: https://youtu.be/n86n3G12kX8 Link to Groq: https://console.groq.com/ We will cover: ✅ What a Deep Agent is ✅ How planning works inside an AI agent ✅ How a Worker Agent executes tasks ✅ How memory is stored using JSON ✅ How to use Groq’s free LLM API ✅ Clean project setup using virtual environments ✅ Complete working code walkthrough By the end of this video, you’ll understand how modern AI agents break down goals, execute tasks, and store memory — just like real-world AI systems. 🧠 What We Build Goal → Planner Agent → Step Execution → Memory Storage You’ll see how a Deep Agent: Takes a user goal Creates a structured plan Executes each step using an LLM Stores results in memory All using free tools. 🛠 Tech Stack Python LangChain Groq (Free LLM API) dotenv JSON Memory System 🚀 Who This Is For Beginners learning AI Agents Developers curious about Deep Agents Students exploring LangChain Anyone who wants to build AI systems without expensive APIs Check 'Python Programming for Beginners' Tamil course at https://www.karthiksshow.com/courses/Python-Programming-for-Beginners-638dbf0ce4b09464540754a9.
