AI Upscaler credits & licenses
What the AI Upscaler is built with, and the licenses that apply.
What we built
LoschaZ designed and wrote the AI Upscaler: the workspace, the two upscaling engines (WebGPU compute shaders and a WebGL2 fallback), the tiling, the resampling, the video pipeline and this page. The video files are read and written with the container code of our Video Compressor.
Components & licenses
- Real-ESRGAN compact models (realesr-general-x4v3 and realesr-general-wdn-x4v3) by Xintao Wang and contributors: the trained network weights the AI mode runs, converted by us to our own half-precision file. BSD 3-Clause License, original project: github.com/xinntao/Real-ESRGAN.
- Outfit, the display typeface of the site: SIL Open Font License 1.1.
- Inter, the text typeface of the site: SIL Open Font License 1.1.
Our changes
The model weights are unchanged apart from the file format (32-bit floats stored as 16-bit floats). The noise slider blends the two models, as the original project describes.
