That animated gif is ridiculously misleading. To someone who doesn't know what's going on, it would look like this can hallucinate Emma Watson's face out of a 5x5 px image.

Instead, this is essentially a fancy 2x upsampling, and the gif shows every other frame as a super-resolution result. In fact, if you look at details like her eye, it's not even doing that great of a result (unsure if this is supposed to be impressive given the current state-of-the-art).
