Nano Banana Pro vs GPT Image 2
Google's Nano Banana Pro and OpenAI's GPT Image 2 ran the same six prompts: a poster, a recipe card, a portrait, a product shot, an edit of an uploaded photo and a busy street at night. Here is what each one made, how they differ, and what an image costs on each. In short: GPT Image 2 was stronger on dense text and on keeping an uploaded photo intact, and Nano Banana Pro made the more natural portrait.

Six prompts on Nano Banana Pro and GPT Image 2
Each pair is the first image each model returned for the same prompt, at a 1:1 aspect ratio and 1K. Pick a prompt to see both results.
A vintage travel poster for a coastal town called "Port Alder". Big headline "PORT ALDER", a smaller line "Ferries daily · Since 1924", a lighthouse at sunset, flat screen-print style.
Both models spelled both lines correctly. Nano Banana Pro went for a worn, printed texture; GPT Image 2 for a painted sunset.
