UnverifiedCompared to LangChain's chain-style invocation, LangGraph introduces loop support, enabling Agents to repeatedly call tools and self-correct until a termination condition is met.74% similarUnverifiedReAct is a prompting and execution pattern and does not necessarily equal an agent by itself—if the number of loops and the tool set are hard-coded, it is closer to a workflow with tools; only when the model genuinely decides dynamically what to do next based on intermediate observations does the ReAct loop form the skeleton of an agent.74% similarUnverified推理-行动循环（ReAct Loop）可以持续多轮，AI分析状态、决定调用工具、获取结果后再规划下一步直至任务完成73% similarVerifiedLangGraph abstracts an Agent's execution process into a persistable, replayable state graph, enabling complex multi-step tasks to resume from a breakpoint after interruption.72% similarUnverifiedLangGraph supports cyclic graph structures, enabling agents to iterate repeatedly in a "think-act-observe" loop until a termination condition is met72% similar
