Gran Turismo Sophy Announced by Sony AI and Polyphony; It’s an AI Breakthrough Capable of Competing Against Top Players
The minds at Polyphony Digital and Sony AI have made a breakthrough in terms of Artificial Intelligence. This new breakthrough is a superhuman artificial intelligence agent that's capable of racing against top human Gran Turismo Drivers. This new venture in Artificial Intelligence is known as Gran Turismo Sophy.
Gran Turismo Sophy is an artificial intelligence agent trained using a novel deep reinforcement learning platform developed in collaboration between Sony AI, Polyphony Digital, and Sony Interactive Entertainment. Each group contributed to the success of the project by bringing together expertise in fundamental artificial intelligence research and development, a hyper-realistic real-world racing simulator, and infrastructure for massive-scale artificial intelligence training.
Sony AI spoke about what makes Gran Turismo Sophy a unique AI Challenge:
The first important point is that racing requires drivers to control physical systems at their limits. Racing is essentially trying to drive cars at the edge of control or just beyond. [...] Racers have to find lines to pass their opponents taking into account the opponent's reaction to the overtake attempts.
That turns racing into a complex back and forth between opponents including defend and pretend behaviors as well as pushing the limits on the racing lines, braking and acceleration points. [...] All these things together distinguish Gran Turismo Sophy from earlier AI agents in chess, shogi, Go and other AI breakthroughs such as AlphaStar and OpenAI Five.
The AI is trained to master skills surrounding race car control, racing tactics, and racing etiquette to bring competition skills on par to human players at the level of the world's best championship levels. According to Sony AI, the agent has a deep understanding of car dynamics, racing lines, and precision maneuvers to conquer challenging tracks.

You can read more about the Gran Turismo Sophy AI through the Sony AI blog, Sony Interactive Entertainment blog, or the Polyphony Digital blog. There's currently no word about when this AI will be implemented in the Gran Turismo games, but it's easy to assume that it will be introduced after the launch of Gran Turismo 7. Gran Turismo 7 will launch on PlayStation 4 and 5 on March 4.
