Gran Turismo SophyTM (GT Sophy) is a breakthrough in AI
featured as a cover article in the Feb 10, 2022 edition of Nature.

Sony AI in partnership with Polyphony Digital, maker of Gran Turismo and Sony Interactive Entertainment, which provided the cloud infrastructure for massive scale AI training, developed a revolutionary superhuman autonomous AI racing agent that outraced the world’s best drivers of the highly realistic PlayStation®4 racing simulation game, Gran TurismoTM (GT) Sport.

Sony AI researchers and engineers developed innovative reinforcement learning (RL) techniques including a new training algorithm called Quantile-Regression Soft Actor-Critic (QR-SAC), agent-understandable encodings of the rules of racing, and a training regimen that promoted the acquisition of nuanced skills for high-speed, wheel-to-wheel racing. Through these key innovations in RL Techniques, GT Sophy mastered the skills of Race Car Control, Racing Tactics and Racing Etiquette, characteristics that are not present in earlier AI breakthroughs.

GT Sophy was developed with a view to how AI agents in games (as opponents or collaborators) can enhance the players’ gaming experience.
