Sony has trained an AI software that defeated top human video gamers in the racing game Gran Turismo Sport.

Gran Turismo Sophy

Two years after it established a new artificial intelligence laboratory, Sony has revealed its first major breakthrough. GT Sophy, an AI agent, beat some of the best human competitors in the popular racing game, Gran Turismo Sport. 

The agent is the result of a collaboration between Polyphony Digital, Sony AI, and Sony Interactive Entertainment using machine learning.

GT Sophy’s abilities were tested when it competed against four top GT drivers in two separate events, Sony AI disclosed. The AI agent showed that it is “reliably superhuman”, comfortably defeating the drivers in back-to-back laps.

“By making improvements to the agent based on the results of the first race, GT Sophy outperformed the best human GT drivers in both time trial races and an FIA-Certified Gran Turismo Championship format race for the second event,” Sony AI said in a Nature article published on Wednesday.

GT Sophy’s training first began in January last year using a machine learning technique called reinforcement learning. 

AI Agents Outperforming Human Gamers

Artificial intelligence is one of the technology trends expected to shape 2022. In addition, it is shaping up to become a mainstay in the blossoming gaming industry.

Different platforms have trained AI not only to master complex games and processes but also to beat expert human competitors. 

For instance, in 2019, Google subsidiary DeepMind unveiled an AI that rose to Grandmaster level in the popular game StarCraft II. This means that it is capable of defeating 99.8% of all human gamers.

It is not a new development either. In 1997, IBM’s Deeper Blue AI beat Gary Kasparov, the greatest chess player of all time.
