Nano Banana vs ChatGPT: Same Prompt, One Looks Like a Real Photo, the Other "Slop"

A side-by-side test using the same prompt — a "casual iPhone photo" of Sam Altman in a ballet tutu — compares Google's Nano Banana (argon high) against ChatGPT image generation with thinking and web search.

The verdict: Nano Banana's output looks like a perfectly real photograph — the author notes that if the scenario weren't absurd, nobody would know it's AI. ChatGPT's image, by contrast, reads as engagement-bait slop: it doesn't look like a phone photo, and arguably doesn't even resemble Sam himself.
