NVIDIA just dropped a crazy new research idea. Get ready.
The same next-token trick behind ChatGPT got pointed at a ragdoll.
Honestly the result is unsettling.
No exotic new architecture.
Chop human motion into a vocabulary of tiny movement tokens.
Train a plain GPT to guess the next one, decode it into muscle commands, let physics run.
Then the strange part shows up. Shove the character and it catches its own step.
Knock it flat and it plants a hand and gets back up.
NOBODY wrote a reward for standing up.
Here is why this rattles robotics people.
Every humanoid team right now is buried under hand-tuned controllers, one for each little skill.
π΅ the old way: script every skill and its reward by hand
π΅ this way: pretrain ONE body on a mountain of motion and the instincts come free
Falling and getting up was never programmed.
It emerged.
Movement is just a language you can autocomplete.
