LangGraph Explained | Graph Components, Nodes & Edges | LangGraph vs LangChain

Welcome back to my YouTube channel SummarizedAI. In today’s video, we break down LangGraph from the ground up and clearly explain all the key graph components that power modern AI workflows. We start by clarifying an important concept: 1. LangGraph is NOT a Knowledge Graph. 2. LangGraph is a workflow and reasoning framework that can use knowledge graphs as a structured data source. You’ll learn how LangGraph works like a smart flowchart for AI conversations, enabling AI systems to: 1. Think before answering 2. Decide next steps 3. Use tools 4. Check results 5. Fix mistakes 6. Repeat until the task is complete We then move into graph fundamentals, including: 1. Vertices (Nodes) 2. Edges (Directed & Undirected) 3. Paths and Path Length 4. Connected Components 5. Cycles (Directed & Undirected) 6. Weighted Graphs To make things practical, we map these graph concepts directly to LangGraph, showing how nodes represent actions, edges control execution flow, and how stateful reasoning is achieved. Finally, we compare LangGraph vs LangChain, explaining: 1. When LangChain is the right choice for linear workflows 2. Why LangGraph is better for complex, multi-step, stateful AI agents 3. Use cases like advanced reasoning, retries, reflection, and production-grade systems In the next video, we’ll dive into Knowledge Graphs and their role in AI/ML, search, and recommendation systems. #LangGraph #LangChain #AIWorkflows #GraphTheory #KnowledgeGraphs #LLM #AIEngineering #AIAgents #MultiAgentSystems #StatefulAI #Python #MachineLearning #ArtificialIntelligence #RAG #AIArchitecture #SummarizedAI
