LangChain & LangGraph for Beginners

🚀 LangChain & LangGraph for Beginners
Build AI Agents, Workflows, and Multi-Step Reasoning Systems Step by Step

Artificial Intelligence is no longer just about asking questions—it’s about building systems that can think, plan, and act.

LangChain & LangGraph for Beginners is your hands-on guide to creating powerful AI applications using two of the most important frameworks in modern AI development: LangChain and LangGraph. Designed for beginners, this book takes you step by step from foundational concepts to building intelligent, multi-step AI systems that can solve real-world problems.

🔍 What You’ll Learn
The fundamentals of Large Language Models (LLMs) and how they power modern AI
How to use LangChain to build structured, modular AI applications
Designing and implementing AI agents that can reason and take actions
Creating multi-step workflows that go beyond simple prompts
Leveraging LangGraph to build stateful, controllable AI systems
Integrating APIs, tools, and external data into your applications
Applying Retrieval-Augmented Generation (RAG) for context-aware responses
Best practices for prompt design, debugging, and scaling AI systems
🧠 Learn by Building
