Hiroaki Kitano, CEO of Sony AI and head of the AI research in Sony Group, shares his thoughts on this achievement, "Gran Turismo Sophy is a significant development in AI whose purpose is not simply to be better than human players, but to offer players a stimulating opponent that can accelerate and elevate the players' techniques and creativity to the next level. At Sony AI our aim is not to replace humans with AI but to create artificial intelligence that will unleash the power of human imagination and creativity."

What kind of AI is Gran Turismo Sophy?

Gran Turismo Sophy was developed by a team of researchers and engineers from Sony AI in collaboration with, Sony Interactive Entertainment, and Polyphony Digital, the developers behind the hit franchise Gran Turismo.

Using novel deep reinforcement learning techniques, Gran Turismo Sophy mastered the highly realistic PlayStation®4 racing simulation game, Gran Turismo™ Sport and became proficient with the driving skills needed to compete with the world's best championship－level Gran Turismo drivers.

The fact that Gran Turismo Sophy was built to elevate the gamers experience is also evident from below comments from Kazunori Yamauchi, the President of Polyphony Digital as well as the top Gran Turismo drivers who played against Gran Turismo Sophy.

"The goal of Gran Turismo Sophy is not to surpass humans through technology, but rather to be an AI that entertains and can be a companion for people."

"I completely forgot that I was playing against an AI. It was really fun. I want to race with the agent more in the future."
Takuma Miyazono, FIA Gran Turismo Championships 2020 Champion
"It was really exciting to see GT Sophy's racing technique. I got a lot of inspiration from her."
