Everyone’s going to obsess over the physics score. But I'm more interested in how little it takes to put this model in a body. Usually you teach a robot its task by showing it that task, over and over, for each new body. Odyssey-3 learns how the world moves first, from internet video, gameplay footage, and simulated physics. After that, the model stays as it is, and each body only needs a small piece trained on its own data. Per Odyssey, robot arms needed tens of hours of demonstrations, and the car’s driving policy used 20 hours. Odyssey hasn’t published success rates, and nobody has reproduced this outside the company yet, so the proof is still ahead.
