Tutorials

Welcome to the LangGraph Tutorials! These notebooks introduce LangGraph through building various language agents and applications.

Quick Start

Learn the basics of LangGraph through a comprehensive quick start in which you will build an agent from scratch.

Use cases

Learn from example implementations of graphs designed for specific scenarios and that implement common design patterns.

Chatbots

RAG

Multi-Agent Systems

  • Collaboration: Enabling two agents to collaborate on a task
  • Supervision: Using an LLM to orchestrate and delegate to individual agents
  • Hierarchical Teams: Orchestrating nested teams of agents to solve problems

Planning Agents

Reflection & Critique

  • Basic Reflection: Prompting the agent to reflect on and revise its outputs
  • Rewoo: Reducing re-planning by saving observations as variables

Evaluation

  • Agent-based: Evaluate chatbots via simulated user interactions
