About this lesson

A world model is a neural network that learns how an environment behaves by watching raw video. You feed it the current state plus an action, and it returns the next state. Loop the output back into the input and it becomes a simulator the network taught itself. Where an LLM predicts the next word, a world model predicts the next moment of reality. Inside, it compresses everything to a latent space (a small bundle of numbers), then learns how that state evolves under each action. That compression is the whole trick: it lets the model imagine thousands of future steps cheaply without ever rendering a frame, and lets agents practice in imagined futures that never actually happened.
