LangChain and Generative AI: Build Practical LLM Applications

Generative artificial intelligence is transforming how we interact with technology, but building reliable applications with large language models requires structured coordination. LangChain provides the essential framework to connect these powerful models to your own data and workflows. This course guides you through the process of building intelligent, context-aware applications using Python and LangChain. You will transition from understanding core artificial intelligence concepts to implementing practical solutions like custom chatbots, data analysis tools, and search assistants. What you'll learn: - Understand the foundational concepts of Large Language Models (LLMs), prompt engineering, and the LangChain ecosystem. - Build interactive conversational agents and chatbots that maintain memory and context across interactions. - Implement Retrieval-Augmented Generation (RAG) to connect LLMs to external data sources and document stores. - Configure vector databases and embeddings to perform efficient semantic search and information retrieval. - Develop structured data analysis tools that can query CSV files and databases using natural language. - Create automated workflows using LangChain chains and agents to solve multi-step reasoning tasks. You will start with key terminology and basic setup before moving step-by-step through written explanations and code walkthroughs for diverse application patterns. Each concept is reinforced with practical text-based exercises designed to build your coding confidence. This course is designed for beginners, software developers, and tech enthusiasts who want to enter the world of AI engineering. No prior experience with generative AI or machine learning is required, though a basic familiarity with Python is helpful.
