This is the prompt I use to test image generator models, and the reason I continue using Nano Banana Pro.
A large, highly detailed, photorealistic image of a spacious, crowded house party room with dozens of diverse people mingling naturally. In the foreground, a table holds: a nearly finished jigsaw puzzle of a medieval castle with exactly three missing pieces placed next to it (holes clearly visible in the puzzle), exactly 23 randomly arranged rocks scattered nearby, a very wide glass and a very thin tall glass each filled with exactly the same volume of red wine (correct liquid levels accounting for glass shapes), a split before-and-after view of a Lego sunflower (left half showing all individual disassembled pieces, right half fully assembled with matching parts), an accurate standard DVORAK keyboard but with the V and K keys precisely swapped, and a 5-panel instructional diagram on how to make toast (exactly 5 panels, consistent toaster). On a central chess table, a top-down view of a full chessboard in a legal midgame position where a white bishop is directly checking the black king (all pieces positioned validly). In the background: a group of about a dozen people lying on the floor forming the letters 'OPEC' clearly with their bodies, five people standing on the ground each holding one correctly colored and interlocked hula hoop to precisely form the Olympic rings symbol, a man sitting on a woman's shoulders while both expertly spin glowing sock poi in circular motion (poi extended straight by centrifugal force), a detailed Where's Wally-style crowded scene on one wall with Wally hidden, a Secret Service agent mid-backflip off a presidential podium (with accurate presidential seal and text), and a man performing poi spins. Dramatic natural lighting, sharp focus everywhere, no artifacts, perfect anatomy and physics, all text and labels fully legible and accurate, highly coherent composition.
