Learn to build sophisticated AI agents using LangGraph in this comprehensive tutorial that demonstrates creating agents capable of planning, utilizing subagents, and leveraging file systems for complex multi-step tasks. Explore the deepagents library, a standalone framework built on LangGraph and inspired by advanced applications like Claude Code, Deep Research, and Manus. Master the implementation of agents with planning capabilities that can decompose complex problems, manage large amounts of context through integrated file system tools, and delegate specialized work to subagents for effective context isolation. Discover when and how to deploy deep agents for tasks requiring sophisticated planning, context management across conversations and threads, and the coordination of multiple specialized components to handle intricate, multi-layered challenges.
