# ReAct: Synergizing Reasoning and Acting in Language Models

by Shunyu Yao et al.

[Read the original →](https://arxiv.org/abs/2210.03629)

Research on combining reasoning with environment actions, a useful reference for agent-loop design.

The paper investigates alternating model reasoning with actions in an environment. It provides research context for agent loops; reproducing results requires implementing and evaluating the surrounding system.
