Chain-of-Thought Prompting Elicits Reasoning in Large Language Models
With Jason Wei, Xuezhi Wang, Dale Schuurmans, Maarten Bosma, Brian Ichter, Ed H. Chi, Quoc V. Le and others ·Showed that giving large language models examples with intermediate reasoning steps can improve their answers to arithmetic, commonsense, and symbolic reasoning problems. The approach became known as chain-of-thought prompting.
