LangGraph is an orchestration framework for building stateful multi-agent applications using LLMs. It provides low-level primitives such as nodes and edges, along with built-in features that give developers granular control over agent workflows, memory management and state persistence. This means developers can start with a simple pre-built graph and scale to complex, evolving agent architectures. With support for streaming, advanced context management and resilience patterns like model fallbacks and tool error handling, LangGraph enables you to build robust, production-grade agentic applications. Its graph-based approach ensures predictable, customizable workflows and simplifies debugging and scaling. Our teams have had strong results using LangGraph to build multi-agent systems thanks to its lightweight and modular design.
LangGraph 是一款面向基于 LLM 的多 agent 应用构建的编排（Orchestration）框架。与抽象程度较高的 LangChain 相比，它提供了更底层的节点（Nodes）和边（Edges）等基本原语，允许开发者精细地控制 agent 工作流、记忆管理与状态持久化。这种基于图的设计使工作流更加可控且易于定制，使得在生产级应用中的调试、扩展和维护变得更加容易。尽管其学习曲线较陡，但 LangGraph 凭借其轻量化与模块化设计，在开发 agent 应用时展现出了强大的灵活性和扩展性。
