Introduction

At this point, you already know how to make AI agents that perform multiple steps, branch, loop, and use tools. That’s a lot, but LangGraph has even more to offer!

By the end of the lesson, you’ll be able to:

• Implement memory systems to let agents retain and use information.
• Design structured output mechanisms for consistent agent responses.
• Incorporate human-in-the-loop interactions for agent oversight and correction.

Past lessons covered a bit about memory and structured output. This lesson will help you build on that foundation. Human-in-the-loop is new, though, and since AI agents still have some limitations, it’s an important topic you won’t want to skip.
