03 — Questions

Which should you choose?

Which is better, Nano Banana Pro or GPT Image 2?

For text to image, voters prefer GPT Image 2 (Nano Banana Pro 1,246 (#16) · GPT Image 2 1,381 (#3)). For image editing, voters prefer GPT Image 2 (Nano Banana Pro 1,390 (#14) · GPT Image 2 1,460 (#4)). Arena scores come from blind, side-by-side human votes on the same prompts; when the gap is inside both models’ error margins we call it a tie. Test your own prompts before you commit.

Which is cheaper?

Nano Banana Pro costs from $0.134/image (1K–2K), up to $0.24/image (4K); GPT Image 2 costs from $0.006/image (1024×1024, low), up to $0.211/image (1024×1024, high). Prices are list rates and change often; check the lab before budgeting.
