ReAct与Chain-of-Thought的本质区别在于：CoT是纯粹推理增强，思维发生在模型内部；ReAct则允许模型在推理中真实调用外部工具并纳入观察结果

UnverifiedBefore ReAct was proposed, the industry mainly relied on Chain-of-Thought (CoT) prompts to guide models in step-by-step reasoning, but CoT's reasoning process could not invoke external tools or perceive execution results midway.80% similarUnverifiedReAct范式与纯推理模型的根本区别在于通过工具调用获取实时环境反馈而非仅凭静态知识推理79% similarVerifiedThe ReAct framework forms a three-part cycle of Thought → Action → Observation, which differs from Chain-of-Thought (CoT) that reasons only within the model internally.79% similarVerifiedCompared to pure Chain-of-Thought reasoning, the ReAct framework reduces hallucinations by introducing external information sources; compared to pure Action mode, it improves decision quality through explicit reasoning steps.76% similarVerifiedThe core idea of ReAct is to interweave the language model's thinking and actions, forming an iterative loop of Think → Act → Observe, which differs from the pure reasoning chain of Chain-of-Thought.76% similar
