VerifiedReAct requires the model to explicitly output a "Thought—Action—Observation" triplet at each step, forming a traceable decision trajectory.78% similarUnverifiedAgent architecture forms such as ReAct, AutoGen, and LangGraph formalize the perception-reasoning-action loop, allowing the LLM to focus on planning and orchestration.78% similarVerifiedThe ReAct framework enables the model to interact with the external environment while reasoning—first reasoning about what to do, then calling external tools to act, then observing the results returned by the tools, iterating in a loop until the task is complete.77% similarVerifiedReAct 智能体的核心是「推理-行动-观察」循环，LLM 分析问题后决定调用工具，观察返回结果，若不满足则继续推理直到给出最终回复77% similarUnverifiedThe core idea of ReAct is to have the LLM complete complex tasks within a loop of thinking, acting, and observing.77% similar
