About
LangGraph is an open-source framework built on top of LangChain, designed to facilitate the creation of cyclical graphs, which are often necessary for agent runtimes. It allows developers to define agent workflows as graphs, with nodes representing processing steps and edges defining transitions between these steps. This graph-based approach elegantly handles branching, looping, and other non-linear procedures, making it suitable for complex, stateful applications.
