Sony AI and Polyphony Digital have released Gran Turismo Sophy, a hyper-realistic AI racing agent for Gran Turismo 7.
The agent is based on research by Sony’s AI researchers and Polyphony Digital’s developers and it fits Gran Turismo’s mission of being the most realistic racing simulation game.
The PlayStation 5 agent was trained on a neural network and moved from a research project to its commercial release after two years of work. It learns the best way to drive through reinforcement training, and then it’s ready to take on humans. The aim isn’t just to put on a good show, as with many racing games. The mission is to create AI that will challenge and even beat the best human racers.
“For the first time, actually, this is a really competitive AI. The built-in AI has been part of Gran Turismo since the start of the franchise,” said Michael Spranger, chief operating officer of Sony AI, in an interview with GamesBeat. “But that AI is a very narrow band. It is an intermediate AI that is too weak to train against humans. It takes some time actually to build an AI that is able to compete at the highest level. And that’s what we did. And that’s based on a technique called reinforcement learning.”
