AIs become smarter if you tell them to think step by step

Using the phrase "let's think step by step" to cajole AIs into taking more logical decisions was first suggested in a May study presented at a computational neuroscience conference. Such "chain-of-thought" prompting encourages these models, which include GPT-3, a text-generating AI developed by …
