Nano Banana Pro vs GPT Image 2
Nano Banana Pro (Google Gemini 3 Pro) and GPT Image 2 (OpenAI) are the flagship image models of the two biggest AI labs, and both excel at understanding complicated prompts. Nano Banana Pro pushes semantic accuracy and up to 4K output; GPT Image 2 is known for text rendering and stylistic range at a lower unit cost.

Choose Nano Banana Pro when
- Marketing and product imagery where getting every prompt detail right matters most.
- You need up to 4K output for large-format or zoom-heavy use.
- Complex compositional instructions that weaker models scramble.
The bottom line
Both are excellent generalists, so the tiebreakers are specific: 4K and semantic precision favor Nano Banana Pro, in-image text and unit economics favor GPT Image 2. Since both bill flat per image on Arteza, the honest advice is to run your three hardest prompts through each and count which needed fewer retries.
Frequently asked questions
Which model renders text inside images better?
GPT Image 2 is particularly strong at legible in-image text. Nano Banana Pro also handles text-heavy creative content well. For dedicated typography like logos and posters, Ideogram V4 is a third option worth testing.
What resolutions do they support?
Nano Banana Pro outputs 1K, 2K, or 4K. GPT Image 2 outputs up to 4K across multiple sizes. Live options are listed in the Arteza image studio for each.
Are both licensed for commercial use?
