UnifiedReward-Edit-qwen3vl-8b

Model Summary

UnifiedReward-Edit-qwen3vl-8b is a unified reward model for both Text-to-Image and Image-to-Image generation!! For image editing reward task, our models support:

1. Pairwise Rank — directly judge which of two edited images is better.

2. Pairwise Score — assign a separate score to each image in a pair.

3. Pointwise Score — rate a single image on two axes: instruction-following and overall image quality.

🚀 The image editing reward inference code is available at UnifiedReward-Edit/ directory, while T2I inference code is unchanged from previous models. The editing training data is preprocessed from EditScore and EditReward. We sincerely appreciate all contributors!!
