It seems all generated images when you land on the page and click the "create human" aren't created live but picked from a pre-populated list images that were also likely pre-filtered for accuracy: it's always almost instantaneous, while any small modification on the same subject always fails returning that the site is at maximum capacity. Also, several users pointed to created images with the usual problems related to hands and other parts. I would not base any judgment on what the site returns on the landing page.
