LangGraph is a library for building stateful, multi-actor applications with LLMs, designed to create robust and complex AI agents.

LangGraph extends LangChain by providing a way to construct agentic workflows as graphs, enabling more sophisticated control flow and state management for AI applications. It allows developers to define sequences of LLM calls, tool usage, and human intervention, making it suitable for building complex, multi-step AI agents that can reason and act over time.

Key Features

Define agentic workflows as graphs
State management for multi-step interactions
Support for human-in-the-loop
Integration with LangChain components
Cyclical and conditional execution paths

Pros

Enables complex, stateful AI agents
Provides fine-grained control over agent behavior
Leverages the LangChain ecosystem
