Details
NitroGen is a novel AI model developed by NVIDIA that can play video games directly from raw video frames. It takes in game footage as input and outputs gamepad actions, allowing it to control the game. The model is trained purely through imitation learning, learning from large datasets of human gameplay videos. NitroGen is particularly effective on games designed for gamepad controls, such as action, platformer, and racing games. It processes the RGB frames through a pre-trained vision transformer called SigLip2, and then a diffusion matching transformer (DiT) generates the appropriate actions conditioned on the SigLip2 output.
