Next-token prediction paper demonstrates real-world humanoid locomotion on Digit

Evidence notes
- The paper casts humanoid locomotion as next-token prediction over sensorimotor trajectories using a causal transformer.
- The authors use Agility Robotics Digit as the physical humanoid platform and report zero-shot real-world walking in San Francisco.
Company context
