Alternatives to PixelCNN

FAQ

What is PixelCNN?
PixelCNN is an autoregressive generative model that generates images pixel by pixel, conditioning each on previous pixels using masked convolutions.
Is PixelCNN available as a SaaS?
No, it is an open-source research implementation available on GitHub, not a hosted SaaS service.
What datasets does it support?
It is demonstrated on CIFAR-10, ImageNet32, and LSUN bedrooms, but can be trained on custom image datasets.
How fast is image generation?
Generation is slow because it samples pixels sequentially; a 32x32 image can take minutes on CPU.
Can it generate conditional images?
The base OpenAI repo is for unconditional generation; extensions like PixelRNN support conditioning.
Is the code still maintained?
The repository dates to 2016 and uses TensorFlow 1.x; it may require porting to modern frameworks.
