About
ImageReward is an open-source project that introduces a general-purpose text-to-image human preference reward model (RM), trained on 137k pairs of expert comparisons. This model significantly outperforms existing text-image scoring methods like CLIP, Aesthetic, and BLIP in understanding human preferences for text-to-image synthesis. The tool also features Reward Feedback Learning (ReFL), which allows for direct optimization of text-to-image diffusion models using ImageReward, resulting in improved human evaluation scores. ImageReward is available as a Python package, enabling users to easily score generated images or fine-tune their own diffusion models with just a few lines of code. It also offers integration into Stable Diffusion Web UI for convenient scoring and filtering of generated images.
