I’d say it’s more like Waymo’s world model. The main actor uses a latent vector representation of the state of the game to make decisions. This latent vector at train time is meant to compress a bunch of useful information about the game. So while you can’t really understand the actual latent vector that represents state, you do know it encodes at least the state of the game.

This world model stuff is only possible in environments that are sandboxed. Ie you can represent the state of the world in an and have a way of producing the next state given a current state and action. Things like Atari games, robot simulations, etc
