models in the line
Nano Banana is Google's image generation and editing line. Every tier does both text-to-image and image-to-image with reference images, and every tier exposes the same unusually wide framing controls — fourteen aspect ratios from 1:8 through 8:1, at 512px, 1K, 2K or 4K. The tiers differ in price and in how much you pay for higher resolutions, not in what they can be asked to do.

Which one to pick
Nano Banana 2 Lite
Volume work — thumbnails, variations, anything you generate hundreds of. The cheapest image model in the catalog at half a cent.
Nano Banana
The original tier, at a flat price regardless of resolution.
Nano Banana 2
The general-purpose choice, with resolution-tiered pricing so 1K work stays cheap and 4K costs more.
Nano Banana Pro
Quality-first output where a flat rate up to 2K matters more than the lowest per-image price.
Strengths
- Fourteen aspect ratios including extreme panoramic and column formats (21:9, 1:8, 8:1) that most image models do not offer.
- Reference-image editing on every tier, including the cheapest.
- An eight-fold price spread within one line and one request format.
- Pro charges the same up to 2K, which makes higher-resolution output predictable to budget.
Limitations
- Resolution pricing is not uniform across tiers — on Nano Banana 2, 512px is priced like 4K rather than like 1K.
- No video output anywhere in the line; pair it with a video family if you need motion.
- The tiers share a parameter surface, so there is no capability reason to pick one over another — only cost and output quality.
