## Summary

A console racing simulator that combines a detailed vehicle dynamics model and car collection with GT Sophy, a deep reinforcement learning opponent added as a permanent rival in 2023.

## Design Notes

Included because it is the clearest shipped case of a learned opponent in a simulation game. GT Sophy, trained with model-free deep reinforcement learning on parallel simulator instances, became selectable as a permanent rival in 2023 and was extended to custom races in 2025, one content update at a time.

## Relations

**influenced by**

- [Gran Turismo](../game/gran-turismo.md)

**uses**

- [Vehicle dynamics](../mechanic/vehicle-dynamics.md) (core): Tire, suspension, aerodynamics, and drivetrain models per car; tuning parts and settings change handling.
- [Embodied skill control](../mechanic/embodied-skill-control.md) (core): Racing lines, braking points, and throttle control on wheel or pad decide results; GT Sophy is trained to the same physics.
- [Collection goals](../mechanic/collection-goals.md) (supporting)
- [Career ladder](../mechanic/career-ladder.md) (supporting)
- [Scenario objectives](../mechanic/scenario-objectives.md) (supporting)
- [Weather](../mechanic/weather.md) (supporting)

## Claims

- GT Sophy 2.0 was added to Gran Turismo 7 as a rival in Quick Race across nine tracks and 340 cars in November 2023. *(confidence: high)* [[35](../source/src-polyphony-2023-gt-sophy-2.md)]
- In 2025 GT Sophy 2.1 extended to Custom Race with tuning, tire, and fuel options. *(confidence: high)* [[36](../source/src-sony-2025-gt-sophy-2-1.md)]
