Seedream 4.0 can also handle much higher resolutions. While most image-to-image GenAI models cap out at around 1 megapixel and require downscaling, Seedream supports images up to full 4K so theoretically you should be able to make noticeably cleaner edits.

Nanobanana has a strong tendency to just return the exact image back to you in those cases. So it's a bit of a pick your poison issue.
I think it comes down to your use-case. If your intent is professional studio grade photograph manipulation then NanoBanana is your best bet. Otherwise Seedream and honestly Qwen are both perfectly servicable.

EDIT: What does "Nano Banana operates directly in pixel space" mean? Information on the internals of Nano-Banana seem to be pretty sparse. Do you have a source for this?
