Скачать или смотреть LangGraph: Architecture for Production LLM Agents

The source provides a comprehensive analysis of LangGraph, an open-source, graph-based orchestration framework designed to build complex, stateful AI agents. It explains that LangGraph was developed to overcome the limitations of linear, chain-based workflows like those in LangChain, enabling cyclical reasoning and advanced features necessary for sophisticated agents. The core architecture is detailed through its three foundational concepts: State (for persistent memory), Nodes (for units of work), and Edges (for control flow and conditional branching). Furthermore, the text distinguishes between the open-source library and the commercial LangGraph Platform, which offers production-grade features such as automated scaling, fault tolerance, and Human-in-the-Loop integration for enterprise deployment. Ultimately, the source serves as a strategic guide, recommending LangGraph specifically for applications requiring multi-step reasoning and multi-agent coordination over simpler tasks.
