 **Playground v2** is a diffusion-based text-to-image generative model. The model was trained from scratch by the research team at [Playground](https://playground.com). 
 
-Playground v2’s images are favored 2.5 times more than those produced by Stable Diffusion XL, according to Playground’s [user study](#user-study).

 We curate the high-quality dataset from Midjourney with 10 common categories, each category with 3K samples. Following common practice, we use aesthetic score and CLIP score to ensure high image quality and high image-text alignment. Furthermore, we take extra care to make the data diverse within each category.
 
-For Playground v2, we report both the overall FID and per-category FID. (All FID metrics are computed at resolution 1024x1024.)
+For Playground v2, we report both the overall FID and per-category FID. All FID metrics are computed at resolution 1024x1024. Our benchmark results show that our model outperforms SDXL-1-0-refiner in overall FID and all category FIDs, especially in people and fashion categories. This is in line with the results of the user study, which indicates a correlation between human preference and FID score on the MJHQ30K benchmark.
 
 We release this benchmark to the public and encourage the community to adopt it for benchmarking their models’ aesthetic quality.
