ReAct, Plan-and-Execute, and Reflexion are three common agent control-flow patterns, differing in who decides the next step; they are essentially the harness's orchestration choices for loop structure, termination conditions, and feedback loops, not model capabilities.

UnverifiedThe ReAct paradigm has spawned variants such as Reflexion, LATS, and Plan-and-Execute.75% similarUnverifiedReAct范式通过将思考（Thought）→行动（Action）→观察（Observation）三元组交织在同一上下文中构建闭环反馈控制系统72% 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.72% similarUnverifiedThe core difference between ReAct and Plan-and-Execute lies in whether dynamic mid-course modification of the plan is permitted.72% similarUnverifiedAgent的失败-修正-再尝试过程被称为ReAct（Reasoning + Acting）模式或反思循环71% similar
