What is Nano Banana 2.1?
Nano Banana 2.1 is Google's October 2026 update to Nano Banana 2, built on the Gemini 3.1 Flash Image family. CVY.AI offers text-to-image and image-to-image workflows with up to four reference images.
It sits between Nano Banana and Nano Banana Pro: more resolution options and better prompt following than the original at a lower credit cost than Pro. Reach for Pro when the image will be scrutinized up close; reach for Nano Banana when you only need quick 1K drafts.
At CVY.AI it costs 4 credits at 1K, 5 credits at 2K and 6 credits at 4K.

The update to Nano Banana 2

1K, 2K and 4K for fewer credits than Pro
Choose the resolution before generating. On CVY.AI, 1K costs 4 credits, 2K costs 5 and 4K costs 6, compared with 8 to 10 for Nano Banana Pro.
- ▸
Reference-guided editing
Upload up to four reference images to edit a photo, keep a character consistent across prompts, or restyle a product shot. Review the result before using it.
- ▸
Wide and panoramic framing
Google highlights wide and panoramic generation in this release. On CVY.AI you can pick 16:9 or 21:9 for banners and headers.
- ▸
Fast turnaround
In our tests a 1K image took about 20 seconds and a 4K image under 40, so it suits iterating on a prompt before committing to a final render.
