## Abstract
While large language models (LLMs) have demonstrated impressive performance across tasks in language understanding and interactive decision making, their abilities for reasoning (e.g. chain-of-thought prompting) and acting (e.g. action plan generation) have primarily been studied as separate topics. In this paper, we explore the use of LLMs to generate both reasoning traces and task-specific actions in an interleaved manner, allowing for greater synergy between the two: reasoning traces help the model induce, track, and update action plans as well as handle exceptions, while actions allow it to interface with and gather additional information from external sources such as knowledge bases or environments. We apply our approach, named ReAct, to a diverse set of language and decision making tasks and demonstrate its effectiveness over state-of-the-art baselines in addition to improved human interpretability and trustworthiness.

## 1. Introduction
A unique feature of human intelligence is the ability to seamlessly combine task-oriented actions with verbal reasoning. Consider the example of a person cooking a dish in the kitchen. Between actions, they may reason in language to track progress ("now that the vegetables are cut, I need to start the pot"), handle exceptions ("I don't have salt, let me check the other cabinet"), and adjust the plan ("it's taking too long, I should increase the heat").

## 2. ReAct: Synergizing Reasoning + Acting
The core idea of ReAct is to augment the action space of the agent to include thoughts, or "reasoning traces".
An action $a_t$ in ReAct can be:
1. **External Action:** Interacting with the environment (e.g., `search[entity]`, `click[button]`).
2. **Internal Thought:** A reasoning trace that does not affect the environment but updates the agent's context (e.g., `Thought: I need to find the author first`).

Formally, at time step $t$, the agent receives an observation $o_t$ and generates a thought $\\tau_t$ or an action $a_t$. This allows the model to perform dynamic reasoning to create, maintain, and adjust high-level plans for acting (Reasoning $\\rightarrow$ Acting), while also interacting with the external environments (Acting $\\rightarrow$ Reasoning).

## 3. Experiments
We evaluate ReAct on two benchmarks: HotpotQA (multi-hop question answering) and Fever (fact verification).
Results show that ReAct outperforms standard prompting and Chain-of-Thought (CoT) prompting.
- **HotpotQA:** ReAct achieves higher exact match scores while reducing hallucination.
- **Interpretablity:** The traces generated by ReAct are more human-readable and grounded.

## 4. Conclusion
ReAct presents a general paradigm to combine reasoning and acting in LLMs. By interleaving thoughts and actions, ReAct overcomes the limitations of reasoning-only or acting-only approaches, leading to superior performance in complex tasks.
