Sony’s new AI driver achieves ‘reliably superhuman’ race times in Gran Turismo

AI agents have bested humans at many games, from chess to Go to poker. Now, the machines can claim a new high score on the classic racing video game series Gran Turismo. Sony announced today that its researchers have developed an AI driver named GT Sophy that is “reliably superhuman” — able to beat top human drivers in Gran Turismo Sport in back-to-back laps. You might think this an easy challenge.

A common concern when testing AI agents against humans is that machines have a number of innate advantages, like perfect recall and fast reaction times. Sony’s researchers note that GT Sophy does have some advantages compared to human players, like a precise map of the course with coordinates of track boundaries and “precise information about the load on each tire, slip angle of each tire, and other vehicle state.
