Build real-world LLM apps and Retrieval-Augmented Generation (RAG) systems using LangChain.

Requirements
No prior experience with LangChain, RAG, or LLMs required – course starts from absolute basics and builds to advanced projects
A computer with internet connection and ability to install Python packages – all tools used in the course are free and open-source
Willingness to learn and experiment with generative AI technologies – course includes hands-on projects and practical implementations
No expensive API subscriptions needed – course covers free-tier options and alternatives for all services including OpenAI and Groq

Description
Master LangChain and Build AI-Powered LLM Applications from Scratch Unlock the power of LangChain — the revolutionary framework transforming how developers build Generative AI and LLM-powered applications.In this hands-on, end-to-end LangChain course, you’ll learn to design, code, and deploy real-world AI apps that use Retrieval-Augmented Generation (RAG), Embeddings, and Vector Databases like FAISS and Pinecone.By the end, you won’t just understand LangChain — you’ll be building production-grade AI systems that connect Large Language Models (LLMs) directly to your data.What You’ll Learn1. Understand what LangChain is and why it’s essential for building LLM-powered systems2. Explore LangChain components, packages, and supporting libraries3. Manage API keys and environment variables securely4. Build your first LangChain-powered LLM app step-by-step5. Master Prompt Templates, Chaining Mechanisms, and Output Parsers (String, JSON, Pydantic)6. Work with Document Loaders to ingest PDFs, text files, and web pages7. Learn advanced Text Splitting techniques for context optimization8. Create and use Embeddings with Hugging Face and Ollama9. Integrate and optimize Vector Databases for fast information retrieval10. Implement FAISS and Pinecone vector stores in real projects11. Build and deploy a complete RAG pipeline using LangChainWhy This Course?This isn’t just another AI theory class — it’s 100% project-driven.You’ll code alongside your instructor, Pratham Chandratre, and build multiple real-world AI apps that connect LLMs to real data sources. Each module moves you from concept → implementation → deployment, with clear explanations, practical examples, and hands-on exercises.By the end, you’ll have a complete portfolio of working AI projects that you can showcase to employers or clients.Who This Course Is ForAI & Data Science Students who want to step into the world of Generative AIDevelopers & Engineers looking to integrate LLMs into their applicationsResearchers & Innovators exploring RAG pipelines and intelligent retrieval systemsTech Professionals building next-gen products with LangChain, OpenAI, and PythonTechnologies You’ll MasterLangChain FrameworkOpenAI GPT APIsHugging Face TransformersOllamaFAISSPineconeVector DatabasesRAG (Retrieval-Augmented Generation)PythonYour Journey Starts HereGenerative AI is the future — and LangChain is at its core.By joining this course, you’re not just learning a tool; you’re learning how to build AI systems like ChatGPT, Copilot, and Claude — from scratch.So don’t wait — enroll today and start building your own intelligent, data-aware applications with LangChain!
