LangGraph is an innovative Python library designed to facilitate the development of stateful, multi-agent systems using Large Language Models (LLMs). It addresses the limitations of traditional frameworks like LangChain, which can struggle with complex AI applications due to rigid workflows and manual memory management. By leveraging cyclical graphs, LangGraph allows for more dynamic decision-making and improved persistence, enabling AI agents to remember context and coordinate actions effectively. This flexibility makes it an ideal choice for building sophisticated AI applications that require human-like reasoning and interaction across multiple steps and components.
