Welcome to This Pony Does Not Exist^*. This site displays a grid of AI-generated pony portraits trained by arfa using nVidia's StyleGAN2 architecture.

The training dataset consisted of ~104k SFW images from Derpibooru, cropped and aligned to faces using a custom YOLOv3 network. The cropping data is archived in this GitHub repository.

The model used transfer learning to fine tune the final model from This Fursona Does Not Exist on the pony dataset for an additional 13 days (1 million iterations) on a TPUv3-32 pod at 512x512 resolution. It was then scaled up to 1024x1024 resolution using model surgery, and trained for an additional 200k iterations to produce the final 1024x1024 model.

The model is available for download here (364MB).
