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.
