An agent in AI is a system powered by a Large Language Model (LLM) capable of making decisions based on context and using external tools like web searches and databases. LangGraph is a Python library that simplifies the creation of these agents by providing tools to structure workflows with nodes, edges, and state management. This guide walks through building a basic chatbot using LangGraph, initializing an LLM, adding memory and tool integration, and enhancing functionality with a web search tool.
