Nano Banana 2 is the name Google uses for its Gemini 3.1 Flash Image model. "Nano Banana" started as the code name of the first model in August 2025, stuck, and now covers the whole family. Version 2 shipped in February 2026 and does two things: it creates images from a description and edits the photos you give it.
The family now has five models, which is easy to mix up. Here is how they differ, based on the specs in the Jantaris catalog.
The Nano Banana family in one table
| Model | Released | Resolution | Reference images | Aspect ratios | Price per image |
|---|---|---|---|---|---|
| Nano Banana | 2025-08 | 1K only | up to 14 | 10 | $0.0359 per image |
| Nano Banana Pro | 2025-11 | 1K, 2K, 4K | up to 14 | 10 | from $0.07 per image |
| Nano Banana 2 | 2026-02 | 0.5K-4K | up to 14 | 14 | from $0.07 per image |
| Nano Banana 2 Lite | 2026-06 | 1K only | up to 10 | 14 + auto | $0.0375 per image |
| Nano Banana 2.1 | 2026-10 | 1K, 2K, 4K | up to 14 | 14 + auto | $0.0699 per image |
For models with several resolutions the table shows the lowest rate; the cost calculator gives the exact 2K and 4K price.
What Nano Banana 2 can do
- Text-to-image and photo edits with up to 14 reference images.
- Up to 4 images per request - Pro and 2.1 return one.
- Extreme aspect ratios: besides 16:9 and 9:16 it does 1:4, 4:1, 1:8 and 8:1 for banners and long strips.
- 0.5K to 4K output - a cheap draft or a print-ready file.
- Optional Google search grounding - the model can look up what something looks like before drawing it.
Google says a 1K image typically completes in 10-30 seconds.
Nano Banana 2 or Pro?
Pro is older but heavier, from the Gemini 3 Pro line. I pick it when fine detail and a long, complex prompt matter - it takes up to 32,000 characters. Version 2 is faster, has more ratios and smaller sizes, so it suits batches and drafts. A side-by-side on the same prompts is in GPT Image 2.5 vs Nano Banana Pro vs FLUX.2.
What about 2.1 and Lite?
- Nano Banana 2.1 (October 2026) succeeds version 2, with one flat price at any resolution and adjustable thinking. If you start today, start there.
- Nano Banana 2 Lite is the speed tier: always 1K, one image, up to 10 references. Good for bulk thumbnails.
