 ## Model Summary
 
-`Unified-Reward-7b-v1.5` is the enhanced version of [Unified-Reward-7b](https://huggingface.co/CodeGoat24/UnifiedReward-7b/blob/main/README.md), the first unified reward model for multimodal understanding and generation assessment, enabling both pairwise ranking and pointwise scoring, which can be employed for vision model preference alignment.
