ReVeR: Pointwise Rubric Reward Models via Tool-Augmented Judging
October 12, 2026
ReVeR implements a pointwise rubric reward model that derives hard rules from instructions alone rather than response candidates. It uses tool-augmented judging and label-blind distillation to eliminate response-induced bias and support direct policy optimization.
