Fast AI Image Generation with Nano Banana 2

Generate high-quality images at up to 4K resolution using Google's Gemini 3.1 Flash model. Nano Banana 2 is optimized for speed, supports text-to-image and image editing with reference images, and offers flexible aspect ratios.

What makes Nano Banana 2 different

From 512px drafts to 4K finals

Nano Banana 2 spans the widest resolution range in the Nano Banana family: a 512px tier at $0.045 per image for rapid drafts, 1K and 2K for everyday work, and full 4K at $0.151 per image for final assets. Iterate cheap, then re-run the winning prompt at 4K — on a Scenetra board that's changing one field on the node and hitting run again.

Built on Gemini 3.1 Flash, tuned for speed

As the Flash-based tier of Google's newest image stack, Nano Banana 2 is optimized for fast turnaround, which makes it the natural pick for iteration-heavy workflows where you generate a batch of variations before choosing a winner. Per image it costs roughly half of Nano Banana Pro — that's exactly the trade it's designed for: near-Pro output at iteration price.

Edit with up to 14 reference images

Beyond pure text-to-image, Nano Banana 2 accepts up to 14 reference images for style, composition, and subject guidance. Keep a character consistent across a series, restyle a product shot, or blend elements from several sources — reference images wire straight into the node's inputs on your board, including outputs from other nodes.

The middle of a three-tier family

Nano Banana 2 sits between the original Nano Banana ($0.039 per image, the volume tier) and Nano Banana Pro (the fidelity tier). On Scenetra all three run side by side on the same board, so you can send one prompt through every tier and compare results directly — no tab switching and no separate subscriptions.

Frequently asked questions

What is Nano Banana 2?+

Nano Banana 2 is Google's Gemini 3.1 Flash image model — the newest fast tier in the Nano Banana family. It generates images from text prompts and edits images using up to 14 references, at resolutions from 512px up to 4K. On Scenetra it runs as a node in the visual workflow editor, alongside Nano Banana Pro and the original Nano Banana.

Is Nano Banana 2 free or paid?+

Nano Banana 2 is a paid model billed per image, but you can try it without paying: new Scenetra accounts start with free welcome credits and a 7-day trial, which covers your first generations. After that you pay per image from your credit balance — from $0.045 at 512px — with no subscription gating the model and nothing to cancel.

How much does Nano Banana 2 cost?+

On Scenetra, Nano Banana 2 costs $0.045 per image at 512px, $0.067 at 1K, $0.101 at 2K, and $0.151 at 4K. You only pay for what you generate — there is no monthly plan required.

Can Nano Banana 2 make 4K images?+

Yes — 4K is a native output option, at $0.151 per image. A common workflow is to iterate at the $0.045 512px tier or the 1K default, then re-run the final prompt at 4K for the deliverable.

Is Nano Banana 2 better than Nano Banana Pro?+

They target different jobs. Nano Banana 2 is faster and roughly half the price per image, which makes it the better default for iteration and volume. Nano Banana Pro is the higher-fidelity tier — stronger on complex edits, realism, and text rendering. On Scenetra you don't have to pick in advance: both are on the same board, so you can run the same prompt through each and compare.

How do I use Nano Banana 2?+

Sign up for Scenetra, drop a Nano Banana 2 node onto your board, type a prompt, and generate. Scenetra is web-based, so it works anywhere without installs, and you don't need a Google API key — generations are billed per image from your credit balance.

Can Nano Banana 2 edit existing images?+

Yes. Attach up to 14 reference images to the node and describe the edit or the style you want in the prompt. References can be uploads or outputs from other nodes on your board, which makes multi-step edit pipelines straightforward.

What aspect ratios does Nano Banana 2 support?+

Eight ratios: 1:1, 2:3, 3:2, 3:4, 4:3, 9:16, 16:9, and 21:9 — covering square, portrait, landscape, vertical social formats, and ultrawide.
