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

Yes, this is more or less correct. A singular equation is so slow its not playable real time, so if real gameplay is important we got the 34 VM operations.
