Noam Brown, who leads AI reasoning research at OpenAI, says “reasoning” AI models like OpenAI’s o1 could’ve arrived 20 years earlier had researchers “known [the right] approach” and algorithms.
“There were various reasons why this research direction was neglected,” Brown said during a panel at Nvidia’s GTC conference in San Jose on Wednesday. “I noticed over the course of my research that, OK, there’s something missing. Humans spend a lot of time thinking before they act in a tough situation. Maybe this would be very useful [in AI].”
Brown is one of the principal architects behind o1, an AI model that employs a technique called test-time inference to “think” before it responds to queries. Test-time inference entails applying additional computing to running models to drive a form of “reasoning.” In general, so-called reasoning models are more accurate and reliable than traditional models, particularly in domains like mathematics and science.
Brown stressed, however, that pre-training
