RAG End to End Explained with LangChain | Vector Databases | Agentic AI

Description

In this video, we will understand RAG (Retrieval-Augmented Generation) end to end — from basic AI foundations to building a real-world chatbot project using LangChain and OpenAI. Here is the GitHub repo link: https://github.com/switch2ai You can download all the code, scripts, and documents from the above GitHub repository. This video covers complete AI foundations before diving deep into RAG: • Introduction to Artificial Intelligence (AI), Machine Learning (ML), Deep Learning (DL) • Data Science fundamentals and feature engineering • Generative AI and real-world examples like ChatGPT, Gemini, Claude • Agentic AI vs AI Agents (Autonomous planning, tool usage, adaptation) • Types of LLMs (Commercial vs Open-source models) • How to get OpenAI API credits step by step • Using LangChain framework with OpenAI and Groq Then we deep dive into RAG architecture: • What is RAG and why it solves LLM limitations • Hallucination problem in LLMs • Context window limitation explained • PDF data extraction using LangChain PyPDFLoader • Chunking strategy using RecursiveCharacterTextSplitter • Embeddings and vector representation • Similarity search using cosine similarity • Vector databases: Pinecone, Milvus, FAISS, Chroma, pgvector • Passing relevant chunks to LLM for accurate responses Real Project Covered: PowerFit Fitness Center Chatbot Building an end-to-end RAG pipeline By the end of this video, you will clearly understand how modern AI systems use Retrieval-Augmented Generation to build production-level chatbots.
