## In depth

### What each maker says
OpenAI released gpt-image-2 on 21 April 2026 in the API and Codex; it powered ChatGPT Images 2.0, and OpenAI highlights instruction following, accurate object placement and dense, multilingual text [1]. Google announced Nano Banana 2 on 26 February 2026, built on Gemini 3.1 Flash Image, highlighting web-grounded knowledge, text rendering and translation, and consistency for up to 5 characters and 14 objects [2].

### Which to pick for what
The models overlap more than they differ. Run the prompt on both, check text word by word, and keep the image that fits.
- Posters, menus, UI mock-ups, infographics with lots of words: GPT Image 2.
- Combining a person, a product and a place from separate photos: Nano Banana 2.
- Large prints or 4K: GPT Image 2 (or upscale a Nano Banana 2 image).
- Cheap, fast drafts: Nano Banana 2 Fast or GPT Image 2.5 Flare.

### How we compared
We ran the same prompts in Kenerate's image generator on both models at their default settings (GPT Image 2 at medium quality, 1K). Specs come from Kenerate's own model settings and from each maker's own announcement.

## FAQ
Q: Is GPT Image 2 better than Nano Banana?
A: Neither wins everywhere. GPT Image 2 is stronger for dense text, layouts and long instructions, and outputs 1K to 4K on Kenerate. Nano Banana 2 fits edits that combine many references and subjects that benefit from Google's web-grounded knowledge. Run the same prompt on both and keep the better image.

Q: Which is better for text in images?
A: GPT Image 2, in our tests: poster titles, a chalkboard menu, a comic speech bubble and an app screen all came out readable. Nano Banana 2 also produced clean text in posters and infographics, but a long infographic repeated one step title, so check every word before you publish.

Q: Which one takes more reference images?
A: GPT Image 2 takes up to 16 reference images on Kenerate, as do GPT Image 2.5 Flare and Sunburst. Nano Banana 2 and Nano Banana 2 Fast take up to 14, and the original Nano Banana up to 10. Say in the prompt which image gives what.

Q: Can either make 4K images?
A: GPT Image 2 renders at 1K, 2K or 4K on Kenerate. Google says Nano Banana 2 supports 512 px up to 4K, but on Kenerate it currently returns square 1K images while size support is being fixed, so upscale the result or use GPT Image 2 for large sizes.

Q: What is the difference between Nano Banana and Nano Banana 2?
A: Nano Banana is Google's earlier lightweight image model, with up to 10 references on Kenerate. Nano Banana 2, announced on 26 February 2026, is built on Gemini 3.1 Flash Image and adds web-grounded knowledge, better text rendering and translation, and up to 14 references.

Q: Do I need ChatGPT or Gemini to use them?
A: No. Both run in Kenerate's image generator without a ChatGPT or Gemini subscription. Neither is on the free plan; any one-time credit pack unlocks both, and packs never expire.

Q: Are there newer versions?
A: On the OpenAI side, GPT Image 2.5 comes in Sunburst, for precision, and Flare, for fast everyday images. On the Google side, Nano Banana 2 Fast is the quicker version for drafts. All are in Kenerate's image generator.
