Sony AI, together with Polyphony Digital Inc. (PDI) and Sony Interactive Entertainment (SIE), today announced a breakthrough in artificial intelligence (AI) called Gran Turismo Sophy (“GT Sophy”) – the first superhuman AI agent to outrace the world’s best drivers of the highly realistic PlayStation® racing simulation game, Gran Turismo™ (GT) Sport. GT Sophy aims to deliver new AI-powered gaming experiences to players around the world.
What is GT Sophy?
GT Sophy is an autonomous AI agent trained utilizing a novel deep reinforcement learning platform developed in collaboration between Sony AI, PDI and SIE. Each group contributed to the success of the project by bringing together expertise in fundamental AI research and development, a hyper-realistic real world racing simulator, and infrastructure for massive scale AI training.
GT Sophy was trained to master the following driving skills needed to compete with the world’s best championship-level drivers.
Race Car Control: Deep understanding of car dynamics, racing lines, and precision maneuvers to conquer challenging tracks.
Racing Tactics: Split-second decision-making skills in response to rapidly evolving racing situations. GT Sophy showed mastery of tactics including slipstream passing, crossover passes and even some defensive maneuvers such as blocking.
Racing Etiquette: Essential for fair play, GT Sophy had to conform to highly refined, but imprecisely specified, sportsmanship rules including avoiding at-fault collisions and respecting opponent driving lines.
Sony AI and its partners built a novel deep reinforcement learning approach and platform since no existing combination of algorithms and infrastructure could solve this challenge. Mastering the complex sport of race car driving in the highly realistic driving simulator Gran Turismo Sport represents a new breakthrough in AI and as such it is published today in Nature in an article titled Outracing Champion Gran Turismo Drivers with Deep Reinforcement Learning.
