Nano Banana 2.1 9 / 10 Ranks second of 13, offering the most compelling inhabited interpretation of the bathhouse. Minor uncertainty in small human details places it just behind the strongest architectural study.
Complex Scenes A busy city intersection with cars, pedestrians, and street performers all in one frame.
A busy city intersection with cars, pedestrians, and street performers all in one frame. - GPT Image 2
GPT Image 2 9 / 10 This is the strongest image in the set because it combines excellent prompt coverage with clear, convincing crowd organization. Small losses of precision in peripheral human details keep it short of a flawless 10.

GPT Image 2 5 / 10 Ranked 6th of 13, this is a natural and coherent expression of appreciation but not the requested sign. Strong photographic realism is outweighed by the incorrect hand location and looser portrait framing.

Nano Banana 2.1 8 / 10 Ranked 2nd of 13, this combines some of the best photographic realism with a substantially more relevant handshape and placement than most alternatives. Slight uncertainty about the exact signing position and the nonplain background keep it below the strongest match.
