First Steps with LangChain: Build an Interactive Quiz Application

Large language models are powerful, but they become truly useful when you learn how to orchestrate their behavior. If you want to move beyond basic API prompts and start building structured AI applications, LangChain is the industry-standard framework to master. In this text-based course, you will transition from a complete beginner to confidently orchestrating AI workflows. You will build a functional quiz-generation application, learning how to structure prompts, parse model outputs, and manage application state. What you'll learn: • Understand foundational LangChain concepts, including models, prompts, and parsers • Compose robust AI workflows using modern LangChain Expression Language (LCEL) • Design dynamic prompt templates that guide language models to generate structured quiz questions • Parse unstructured model responses into clean, usable Python data structures • Manage conversation state and application flow for interactive user experiences • Apply best practices for error handling and model selection in LLM-based applications. The course starts with essential definitions and foundational concepts of LLM orchestration before moving step-by-step through setting up your environment, writing your first chain, and assembling a complete quiz application. You will read clear explanations, analyze code snippets, and complete hands-on text exercises. This course is designed for beginner Python developers who want to start building AI-powered applications. No prior experience with LangChain or machine learning is required.
