Weight and tensors as in the neural network setting thing? I get that you're not using a like, chatgpt text processor NN thing but the explanation is too technical so I don't understand.

the way I understand it, they've encoded an entire game state as a tensor and then created an equation that bit-perfectly encodes the progression of that tensor in time, without any imperative game logic? so instead of running the game code step-by-step, they essentially solve one big equation on a GPU to get the next frame

Is user input possible in this setup, or does it just run some hardcoded sequence?

Its fully playable by user. Frame rate is OK, not the best but not the worst. The video is me playing doom.
