GPT Image 2 vs Nano Banana Pro
GPT Image 2 and Nano Banana Pro (Gemini 3 Pro Image) are both studio-quality image models that render legible in-image text and reach 4K. The difference is philosophy: GPT Image 2 offers OpenAI's instruction-following and a 16-reference ceiling, while Nano Banana Pro brings Google DeepMind's reasoning stack, world knowledge, and precise composite-layout control. On HiArt you can run both on the same canvas - this guide helps you decide which to reach for first.
Side-by-side
| GPT Image 2 | Nano Banana Pro | |
|---|---|---|
| Best for | Layout-heavy brand and editorial with the most references | Studio finals, mockups, and composite layouts |
| Reference images | Up to 16 | Up to 14 |
| Max resolution | 4K (1K/2K/4K) | 4K (1K/2K/4K) |
| Aspect ratios | 14 presets, 1:1 to 21:9 | 10 presets, 1:1 to 21:9 |
| Text & typography | Strongest in-image text, many scripts | Multilingual in-image text, localization-friendly |
| Speed & cost | Quality tiers (low/med/high), ~30s | Precision tier, ~30s |
Which should you choose?
Choose GPT Image 2 if
