LangGraph is a specialized Python library designed for building stateful, multi-agent systems within the LangChain framework. It enables developers to create complex AI applications that can remember context, make dynamic decisions, and coordinate multiple AI components. Unlike traditional linear workflows, LangGraph utilizes a graph-based orchestration framework, allowing for flexible and adaptive interactions. This capability addresses limitations found in simpler systems, such as manual memory management and rigid workflows, making it ideal for applications that require nuanced human-in-the-loop interactions and complex task execution. LangGraph empowers developers to design advanced conversational AI workflows effectively.
