Which thumbnails, ads and storyboards suit Lite?

Google built Lite for quick ideas, ad tests and storyboards: images that live on a screen, carry a few words and get compared before one is kept.

Video thumbnail: a woman in a tangerine kayak jacket nose to nose with a harbor seal, beside the headline SEAL SAID HI

Video thumbnails with a short headline

Put three or four big words on one side and the subject on the other. Lite keeps short, large lettering readable; proofread every headline before it goes live.

Three comic panels of the same otter barista in glasses and a red bandana: pouring milk, getting splashed, holding up a heart latte

Storyboard frames with one recurring character

Sketch three beats of a short ad or animation with the same character, then pick the frame to develop or to use as the first frame of a video.

Three vertical story ads for the same red SLURP CO. ramen cup with the headline LUNCH IN 3 MIN, each in a different layout

Ad versions from one brief

Keep the product and the headline fixed and compare layouts side by side. Lite turns results around fast enough to run another round once one version leads.

How-to card on sand-colored paper: three steps for folding a paper airplane, labeled FOLD IN HALF, FOLD THE NOSE and FOLD THE WINGS

Explainer cards with short labels

Step-by-step cards for a blog post, slide or social carousel, with one short label per step. Write the steps into the prompt yourself instead of asking Lite to work them out.

When is Lite enough, and what does moving up cost?

How do you keep Lite's text and characters right?

Google recommends detailed, descriptive prompts. These habits also steer around the few places where Lite slips.

Write it like this

  1. Describe the scene in full sentences

    Cover the subject, setting, light, framing and what the image is for, such as “a thumbnail for an outdoor travel channel”.

  2. Quote the headline and say where it goes

    Keep it to a few large words, for example: a headline on the left third that reads "SEAL SAID HI".

  3. Paste the same character description every time

    Name, age, outfit and one detail that stands out, copied word for word into each prompt.

  4. Use the image count for versions

    Pick up to 4 images per run, then change one thing for the next round: layout, background or headline.

Avoid these

  1. Asking for “four versions” in the prompt

    The image count setting decides how many you get; numbers written in the prompt are ignored.

  2. Small print or whole paragraphs

    Fine text often blurs at 1K. Give text-heavy layouts to Nano Banana 2.1.

  3. Trusting the figures in a chart

    Lite can draw a convincing chart or diagram, but check every number and claim in it.

  4. Relying on left and right

    Lite sometimes swaps sides. State positions plainly and check them in the result.

Example prompt: “A YouTube thumbnail for an outdoor travel channel. On the right, a woman in a tangerine kayak jacket is nose to nose with a curious harbor seal in bright turquoise water. On the left third, a huge white headline with a thick black outline reads "SEAL SAID HI". Bright midday sun. No other text in the image.”

What people ask before choosing Nano Banana 2 Lite

What is Nano Banana 2 Lite?+

Nano Banana 2 Lite is the Lite tier of Google DeepMind's Nano Banana image family. Its technical name is Gemini 3.1 Flash-Lite Image, and it was released on June 30, 2026. It is built on Gemini 3.1 Flash-Lite, Google's text model, and outputs 1K images. Google also lists it as the recommended replacement for the original Nano Banana (Gemini 2.5 Flash Image).

Should I use Lite or Nano Banana 2.1?+

Switch to Nano Banana 2.1 when the image needs something Lite can't give: a photo or product as a reference (up to 14 images), a bigger file (1K, 2K, 4K) or a text-heavy layout. Nano Banana 2.1, released on October 6, 2026, is Google's newer model and reasons before it draws. For text-only rounds of thumbnails, ad versions and storyboards, Lite is enough; the table above lists the credits for each step.

How does Lite compare with Nano Banana 2 and Nano Banana Pro?+

In Google's own evaluations, Lite is close to Nano Banana 2 for text-to-image but behind on editing, changing text and scenes with several characters. On Oeneo AI, Nano Banana 2 costs more per image and suits continuing a series you started with it. Nano Banana Pro is for five-person shots, logos placed on products and continuing existing Pro work.

How much does Nano Banana 2 Lite cost, and is it free?+

It isn't free, but the 10 credits every new account gets, valid for 365 days, are enough for at least one image. After that, each 1K image costs 8 credits, and the Workbench shows the total before you generate; the table above compares every Nano Banana model, and some other models cost less, such as Z-Image Turbo at 1 credits. Images made on the free plan are public, paid plans keep them private, and failed generations are refunded automatically.

Can Nano Banana 2 Lite make 2K or 4K images?+

No. Lite outputs 1K only. For a larger file, enlarge the result with Image Upscaler, or run the prompt in Nano Banana 2.1, which outputs 1K, 2K, 4K.

Can I upload a photo or a reference image?+

Not with Lite on Oeneo AI. Google's model can edit images, but here Lite works from text only. To edit a photo or keep a real product or face, use Nano Banana 2.1, which accepts up to 14 reference images.

Why is the text in my image misspelled or blurry?+

Lite handles short, large text best: a headline, a sticker word, a label. Google notes that small text is often blurry at 1K and long paragraphs are unreliable. Put the exact words in quotes, keep them to a few words and say where they go. If stray lettering appears, add "no other text in the image". Proofread before publishing.

How fast is Nano Banana 2 Lite?+

It is the fastest model in Google's Nano Banana family; Google reports text-to-image results in about 4 seconds on its own API. On Oeneo AI the total also includes queueing and saving your images, so it varies. Nano Banana 2.1 reasons before it draws, which takes longer.

Can I use the images commercially? Is there a watermark?+

Yes, on a paid plan: paid Oeneo AI plans include a commercial license, and the Lifetime plan covers personal commercial use (see Pricing). Google embeds an invisible SynthID watermark in every image so it can be identified as AI-generated; there is no visible mark. Whether a specific image is safe to publish still depends on what it shows, such as real people, brands or artwork.

Run your next brief through Lite

Write the scene, quote the headline and compare a few versions. When the one you keep needs more, move it up.
