ChatGPT Images 2.0 vs Nano Banana 2: Which AI Image Tool Wins for Real-World Tasks?

AI image models are getting good enough that “Which one is better?” is no longer a very useful question on its own. The better question is… better at what?

A model that nails a polished product photo might struggle with a professional headshot. One that creates a beautiful scene may still miss the exact layout, lighting, or text instructions in the prompt. So I tested ChatGPT Images 2.0 and Google’s Nano Banana 2 head-to-head using the same six prompts across practical, everyday image tasks.
