Reasoning in the physical world can be really well expressed as a world model. In 2018, we put our very first world model approach on the road. It was a very small 100,000 parameter neural network that could simulate a 30x3 pixel image of a road in front of us.But we were able to use it as this internal simulator to train a modelbased reinforcement learning algorithm. Fast forward to today and we've developed a GIA. It's a full generative world model that's able to simulate multiple camera and sensors and v ...
