   Chelsea Finn: Generative value classifiers are a new parameterization of Q-functions

She believes such methods may combine well with large pretrained policies and learn and generalize better from richer output signals. The quoted post notes that robot policies cannot directly score outputs the way language models can, and typically require training a separate critic from sparse rewards.
