TL;DR
Compare Nano Banana, Nano Banana Pro, and Nano Banana 2 for image generation and image editing.
Three tiers, one family
The Nano Banana family covers three quality tiers — base, Pro, and Nano Banana 2 — each available in both text-to-image and image edit variants.
The base model is the cheapest lane for fast iteration. Pro steps up quality at a higher cost per image. Nano Banana 2 sits between them on both dimensions.
When to choose Nano Banana
- Use the base model when you want cheaper prompt iteration.
- Use Pro when quality matters more than credit cost per image.
- Use Nano Banana 2 as a middle option between cost and quality.
- Use the edit variants when you need reference-image changes instead of fresh generation.
