LangGraph is an innovative Python library designed to facilitate the development of stateful, multi-agent applications using Large Language Models (LLMs). It addresses the limitations of traditional frameworks by enabling more complex AI systems that can remember context, make dynamic decisions, and coordinate multiple AI components. Unlike linear workflows, LangGraph employs a graph-based orchestration framework, allowing for flexible and cyclic processing. This capability enhances the scalability and adaptability of AI agents, making it easier to implement sophisticated interactions and workflows. LangGraph is particularly beneficial for applications requiring human-in-the-loop interactions and persistent memory management.
