What the evidence indicates

A concise reading of the source

The reported RL-token method keeps the main VLA fixed while training a smaller actor and critic on a compressed internal representation.

FUURAA interpretation

Why this could matter

Deployed robots may adapt difficult task phases locally without retraining an entire foundation model.
