+## Model Summary
+
+`UnifiedReward-2.0-qwen3vl-8b` is the first unified reward model based on [Qwen/Qwen3-VL-8B-Instruct](https://huggingface.co/Qwen/Qwen3-VL-8B-Instruct) for multimodal understanding and generation assessment, enabling both pairwise ranking and pointwise scoring, which can be employed for vision model preference alignment.
