The Nano Banana Family Explained
Google's Nano Banana models have confused a lot of users with their rapid releases and shifting names. If you're trying to figure out which one to use, this complete comparison breaks down every version.

Each version improved image quality — better hands, more accurate text, sharper details, stronger style control. But the watermarking system never changed. Regardless of which Nano Banana model generated your image, the visible watermark is:
- The same star/sparkle logo
- In the same bottom-right position
- Applied with the same alpha compositing technique
- Sized 48×48 (up to 1024px) or 96×96 (larger)
