Sony Interactive Entertainment unpacked a new AI system, built in collaboration with Sony AI, Polyphony Digital and its cloud gaming team — Gran Turismo Sophy†
The format holder announced the technology at its Race Together Media Event, where it claimed GT Sophy can race competitively against the best Gran Turismo players in the world, and was tested with the PS4 racer Gran Turismo Sport.
Development testing for the technical GT Sophy pitted it against four of the world’s top GT Sport players in two events, one of which took place in July 2021 and the other a few months later. The first saw the AI system score 70 points over three races, with the human-controlled team achieving 86 points.
Later on, GT Sophy managed to improve its performance to 104 points in a second round of testing, compared to the human team’s 52 points. As if that wasn’t impressive enough, the AI tech won every race and set the best lap time.
The technology leverages Sony’s cloud gaming infrastructure for training through an in-depth reinforcement learning system, focusing on three areas: physical realism, real-time racing tractions and sports etiquette.
However, it’s worth pointing out that, despite its name, GT Sophy will not be making an appearance in the coming Gran Turismo 7 for PS4 and PS5. That said, Sony AI COO Michael Spranger noted:
Sony AI and PDI will explore how GT Sophy can be integrated into future releases of the Gran Turismo series.
