A developer created a tiny world model using looped transformers that runs entirely on a Raspberry Pi Pico 2 W microcontroller. The system uses two small neural networks—one generates game frames by predicting the next state and reward, while the other acts as an RL agent playing within its own generated environment.
Background
World models are neural networks that learn to predict the outcomes of actions in an environment, commonly used in reinforcement learning research. Running such models on resource-constrained microcontrollers represents an emerging trend in efficient AI deployment.
