Gemini (the product) is a mix of an LLM plus image model plus agentic tooling. Is not apples to apples.
A fairer comparison would be Krea Agent with Krea 3 as image model. So you could have grounding, web search, verification models that assess results, etc.
If you told me Nano Banana Pro and that’s it, that’s a different story.
I understand what you're saying. My first thought is "is that really applicable to a mistake like the text on the T-shirt extending over the suit jacket that partially covers it?" Maybe it is. I also don't know what you actually get when you prompt Krea 3 via their website as I did today. I don't know whether that folds in some guidance from an LLM first. Tough to say.
