UnifiedReward-2.0-qwen3vl-4b

Model Summary

UnifiedReward-2.0-qwen3vl-4b is the first unified reward model based on Qwen/Qwen3-VL-4B-Instruct for multimodal understanding and generation assessment, enabling both pairwise ranking and pointwise scoring, which can be employed for vision model preference alignment.
