Before you use it
This is classic machine learning, not a chat model. It trains behaviour, it does not write dialogue.
Why it's useful
You set up a scene, reward the behaviour you want, and it trains a small model that drives an enemy, a racing car or a test bot. Handy for opponents that feel less scripted, and for bots that hammer a level looking for exploits and balance problems.
What it needs
Unity and Python with PyTorch. Training is quicker with an NVIDIA GPU but runs on CPU.
