Gran Turismo
Using AI?
Enhanced user engagement and game longevity through more realistic and challenging NPC behavior.
Project Overview
Sony AI’s GT Sophy uses reinforcement learning to control NPC race car drivers in Gran Turismo 7, enabling more competitive, human-like gameplay.
Layman's Explanation
The game’s virtual racecar opponents now learn to drive like real humans by training through trial and error, making the racing experience feel more authentic and challenging.
Analogy
GT Sophy is like a seasoned esports coach who trains NPC racers to not just follow rules but think and react like skilled human players, making gameplay more lifelike.
Details
Sony AI's GT Sophy is an advanced AI racing agent trained through deep reinforcement learning to compete at a high level in Gran Turismo 7. The March 2025 update integrates a refined version of GT Sophy into everyday gameplay, giving players ongoing access to AI drivers capable of learning and adapting to various racing conditions and styles. This AI is not scripted; instead, it learns optimal behaviors through millions of simulated races, using neural networks to master complex control tasks like cornering, overtaking, and defensive driving. The AI’s incorporation into live gameplay raises the bar for in-game opponents, offering players a more immersive and challenging racing experience while also acting as a showcase for generalizable, high-performance AI in entertainment applications.
