VerifiedIn LangGraph, HITL (Human-in-the-Loop) is implemented through a breakpoint mechanism, where the Agent pauses at a node, serializes and persists the state, and resumes execution after human confirmation75% similarUnverifiedLangGraph abstracts an Agent's execution process into a persistable, replayable state graph, enabling complex multi-step tasks to resume from a breakpoint after interruption.74% similarUnverifiedStreaming execution allows the Agent to output intermediate results in real time, and checkpoint & resume ensures that long-running tasks can continue from the last interruption point when a failure occurs74% similarUnverifiedReAct的思考—行动—观察循环机制使Agent在处理多步骤复杂任务时表现出更高可靠性，显著减少幻觉和错误累积73% similarUnverifiedHaving the model roll forward a number of steps and then roll backward the same number of steps should ideally return to the starting point, and the discrepancy between the actual return position and the starting point serves as a self-supervised proxy metric for unobservable rollout error.73% similar
