ActiveUltraFeedback is a modular pipeline for collecting high-quality preference data more efficiently.
By using uncertainty-aware response selection, it identifies informative response pairs for annotation
and can achieve strong downstream performance with substantially fewer labels than static baselines.

RewardUQ provides a unified framework for evaluating uncertainty quantification in reward models.
It compares common methods in terms of accuracy and calibration, helping clarify which design choices
matter most for reliable reward modeling in LLM alignment.
