ChatGPT Image 2.5 vs Nano Banana 2.1 on a character sheet prompt
The same Claude-written prompt was run on ChatGPT Image 2.5 and Nano Banana 2.1, and the author chose ChatGPT's result for its detail and more accurate bob hairstyle.



I saw @preciousjimoh’s post about ChatGPT’s image generation yesterday, and it reminded me of when I was trying to create a character sheet for this fashion video and wasn’t exactly sure what I wanted her face to look like. All I knew was that I wanted a gorgeous woman with a short bob hairstyle who could really body the outfits. 😙 So I explained what I had in mind to Claude. I tested the prompt it gave me on Nano Banana 2.1 and ChatGPT Image 2.5, and here are the results… Both actually did a good job, but I picked that of ChatGPT’s because it paid attention to details, and got that “baddie” look right. Also, the shape and styling of the bob were almost exactly how I imagined them. Anyway, image 1 is from ChatGPT and image 2 is from Nano Banana. Compare the results. 🌞
