 # You Only Sample Once (YOSO)
 
-This algorithm was proposed in YOSO. 
+This algorithm was proposed in You Only Sample Once: Taming One-Step Text-To-Image Synthesis by Self-Cooperative Diffusion GANs. 
 
-This model is fine-tuning from PixArt, enabling one step inference to perform text-to-image generation.
+This model is fine-tuning from [
+PixArt-XL-2-512x512](https://huggingface.co/PixArt-alpha/PixArt-XL-2-512x512), enabling one-step inference to perform text-to-image generation.
 
 ## usage
