Tiny World Model Runs Games on Raspberry Pi Pico 2 W

A developer used two small neural networks to generate and play games on a Raspberry Pi Pico 2 W: a world model predicts the next frame and reward, while an actor network picks actions. The world model uses a looped transformer with 26k–131k parameters and 2–8M multiply-adds per frame, enabling real-time operation on a microcontroller.
