After 8 years of running waifu2x without monetization we decided to use the GPU server for other projects. 

In all those years, AI image generation has advanced so rapidly that at this point there are better alternatives to waifu2x. 

Our site also runs slightly outdated models compared to the original. If you still want to use waifu2x please use the original generator https://www.waifu2x.net/

 

Alternatively, you could use https://github.com/AUTOMATIC1111/stable-diffusion-webui to set up your own upscaler and AI image generator. 

At this point, there are more than 10 different algorithms for upscaling both anime and real images. 

 

There are even tools to upscale entire anime episodes, such as https://github.com/k4yt3x/video2x
