Ranking image generation models the way Design Arena does it — 26,000 battles, 62 seconds per generation — takes 20 days of compute, costs $5,000, and consumes roughly 400 marathons worth of energy. Bertrand Charpentier, cofounder and chief scientist at Pruna AI, uses that number to make a point: the same evaluation on
