See What Nano Banana 2 Actually Renders

You set the prompt, the resolution, and the ratio, and Nano Banana 2 fills in the rest. Every card below comes from a real capability — resolution choice, native framing, and text that reads right inside the image itself.

One fixed resolution forces every image into the same cost and the same wait.

Pick 1K, 2K, or 4K — Match the Resolution to the Job

Nano Banana 2 renders natively at 1K, 2K, or 4K, selected before you generate. Draft cheap at 1K, then re-run the keeper at 4K once the composition is right.

Frame It Right the First Time in 11 Aspect Ratios

Choose from 1:1, 9:16, 16:9, 3:4, 4:3, 3:2, 2:3, 5:4, 4:5, 21:9, or let Nano Banana 2 auto-frame the shot. Native framing for Reels, banners, and print, without a single crop job.

AI images that need real words on them usually botch the text.

Render Posters, Logos, and Infographics With Text That Actually Reads

Nano Banana 2 places legible, stylized text directly into the image — fonts, sizes, and styles included. One prompt produces a finished poster, mockup, or diagram, not a placeholder you fix in another app.

Get Straight Answers on Nano Banana 2 Before You Generate

You get the honest version here — what Nano Banana 2 actually is, what it costs per resolution, and how it's different from Nano Banana Pro.

What is Nano Banana 2?

Nano Banana 2 is Google's public nickname for Gemini 3.1 Flash Image, one of four models in the Nano Banana image family (alongside the original Nano Banana, Nano Banana 2 Lite, and the higher-tier Nano Banana Pro). Google describes it as a versatile, generalist model that balances speed with state-of-the-art 4K generation, real-world knowledge, and reliable in-image text rendering. On Seadanse, you generate stills on Nano Banana 2 from a text prompt, choosing your own resolution and aspect ratio.

Is Nano Banana 2 the same as Nano Banana Pro?

No — they're different models in the same family. Nano Banana 2 (Gemini 3.1 Flash Image) is Google's versatile, workhorse tier, balancing speed with 4K output. Nano Banana Pro (Gemini 3 Pro Image) is the tier above it — Google's own description calls it "the premium choice for the most complex visual tasks." Seadanse runs Nano Banana 2, not Pro.

Is Nano Banana 2 free to use on Seadanse?

Sign-up is free and needs no credit card. You get 120 one-time starter credits as a head start — enough for a real batch of Nano Banana 2 renders, not just one teaser image. Nano Banana 2 currently bills 7 credits at 1K, 11 at 2K, and 16 at 4K (pricing subject to change). Top up with a credit pack or subscription once your starter balance runs out.

How much does a Nano Banana 2 image cost?

Nano Banana 2 prices by resolution: 7 credits at 1K, 11 credits at 2K, and 16 credits at 4K. The estimate shows beside Generate before you submit, so the charge never surprises you.

What resolution and aspect ratio does Nano Banana 2 support on Seadanse?

Every render offers three resolutions — 1K, 2K, or 4K — and 11 aspect ratios, from 1:1 and 9:16 to 21:9, plus an auto option. Every image downloads as a ready-to-use JPG.

Can I upload a reference photo or edit an existing image with Nano Banana 2?

Not yet on Seadanse. Google's Nano Banana 2 does support reference images and multi-turn editing, but that path isn't open on this page today — here, Nano Banana 2 generates from a text prompt alone. If that changes, this page will say so.

Does Nano Banana 2 generate video too?

No. Nano Banana 2 is a still-image model — every render on this page is a picture, not a clip. If you want to animate a still, generate it here first, then bring it to one of Seadanse's video model pages as a separate step.

Does Nano Banana 2 add a watermark to my images?

Every image downloads without a Seadanse-added mark. Google states that Nano Banana 2's own outputs carry SynthID, an invisible digital watermark used only to identify AI-generated images — it isn't a visible logo or crop on the picture.

What happens if my Nano Banana 2 render fails?

The credits come back automatically, so you never pay for a failed render. Your history keeps every finished image for replay, download, or regeneration.

How is Nano Banana 2 different from the original Nano Banana?

Nano Banana (Gemini 2.5 Flash Image) is the original, legacy model — Google's own docs now recommend moving off it. Nano Banana 2 (Gemini 3.1 Flash Image) is the newer, faster successor, with a higher resolution ceiling and stronger multi-reference handling at the source. Seadanse runs Nano Banana 2, not the original.
