Feature by feature
What it costs
When to pick which
Shooting photoreal portraits or product heroes
Skin, materials, and cinematic lighting read as genuinely camera-shot.
Designing posters, menus, or infographics with real text
Only GPT Image 2 renders small body text as readable type, not pseudo-text.
Editing or iterating on an existing image
Grounded edits and multi-image control make iterative changes reliable.
Mocking up a UI or multi-panel layout
Tight prompt adherence and structural control handle complex, multi-element comps.
Our recommendation
Stop looking for one winner. For anything photoreal — portraits, products, lifestyle — Nano Banana Pro is the sharper tool. For anything with text or strict layout — posters, infographics, UI — GPT Image 2 is. The smartest setup keeps both and lets the prompt decide; if you must crown one all-rounder, GPT Image 2 edges it for the wider range of jobs.
