Well, yea. It says as much on the page:<p>&quot;one is painted by a human and another one is generated by artificial intelligence based on a photo and a style of a painter.&quot;<p>I find this to be easily &quot;beatable&quot; by simply judging which one is most likely to have its origin in a photo (vanity, and such) with a fallback on the one with a lot of repeating patterns.
