-*This leaderboard is retrieved from answers of [Community Evaluations on Parti Prompts](https://huggingface.co/spaces/OpenGenAI/open-parti-prompts)*
+The *Open Parti Prompts Leaderboard* compares state-of-the-art, open-source text-to-image models to each other according to **human preferences**. \n\n
+Text-to-image models are notoriously difficult to evaluate. [FID](https://en.wikipedia.org/wiki/Fr%C3%A9chet_inception_distance) and 
+[CLIP Score](https://en.wikipedia.org/wiki/Fr%C3%A9chet_inception_distance) are not enough to accurately state whether a text-to-image model can 
+**generate "good" images**. "Good" is extremely difficult to put into numbers. \n\n
+Instead, the **Open Parti Prompts Leaderboard** uses human feedback from the community to compare images from different text-to-image models to each other.

-In the [Community Parti Prompts](https://huggingface.co/spaces/OpenGenAI/open-parti-prompts), community members select for every prompt
-of [Parti Prompts](https://huggingface.co/datasets/nateraw/parti-prompts) which open-source image generation model has generated the best image.
-The community's answers are then stored and used in this space to give a human evaluation of the different models. \n\n
+In more detail, the [Open Parti Prompts Game](https://huggingface.co/spaces/OpenGenAI/open-parti-prompts) collects human preferences that state which generated image 
+best fits a given prompt from the [Parti Prompts](https://huggingface.co/datasets/nateraw/parti-prompts) dataset. Parti Prompts has been designed to challenge
+text-to-image models on prompts of varying categories and difficulty. The images have been pre-generated from the models that are compared in this space.
+For more information of how the images were created, plesae refer to [Open Parti Prompts](https://huggingface.co/spaces/OpenGenAI/open-parti-prompts).
