Welcome to LangGraph 101!
Welcome to LangGraph 101! In this session, you will learn about the fundamentals of LangGraph through a series of notebooks. This is a condensed version of LangChain Academy, and is intended to be run in a session with a LangChain engineer. If you're interested in going into more depth, or working through a tutorial on your own, check out LangChain Academy here! LangChain Academy has helpful pre-recorded videos from one of our LangChain engineers.
At LangChain, we aim to make it easy to build LLM applications. One type of LLM application you can build is an agent. There’s a lot of excitement around building agents because they can automate a wide range of tasks that were previously impossible.
In practice though, it is incredibly difficult to build systems that reliably execute on these tasks. As we’ve worked with our users to put agents into production, we’ve learned that more control is often necessary. You might need an agent to always call a specific tool first or use different prompts based on its state.
To tackle this problem, we’ve built LangGraph — a framework for building agent and multi-agent applications. Separate from the LangChain package, LangGraph’s core design philosophy is to help developers add better precision and control into agent workflows, suitable for the complexity of real-world systems.

Navigate to setup.md in the /notebooks/ folder and follow instructions there! If you run into issues with setting up the python environment or acquiring the necessary API keys due to any restrictions (ex. corporate policy), contact your LangChain representative and we'll find a work-around!
