THE ORIGINAL MODEL

What Is Nano Banana?

Original Nano Banana is Google's Gemini 2.5 Flash Image model, built for fast 1K image generation and natural-language photo editing. On CubistAI, it can turn a prompt into a new image or transform one uploaded reference while following requests about composition, style, lighting, backgrounds, and details to preserve.

CubistAI is a third-party interface for the model, not an official Google product. This page uses the original legacy version, not Nano Banana 2.

Prompt-to-Image Creation

Turn a concise or detailed description into a new 1K image across square, portrait, landscape, and ultrawide formats.

Natural-Language Editing

Upload one reference and describe the change in everyday language, from replacing a background to restyling a room.

Details You Can Ask to Preserve

Tell the model to retain identity, pose, layout, product proportions, or brand colors while it edits the requested elements.

A Lower-Cost Starting Point

Each output costs 8 credits, and any signed-in account with enough credits can use the model without a paid-plan requirement.

Original Nano Banana vs Nano Banana 2

Choose the original model for affordable 1K drafts and edits, or move to Nano Banana 2 when your workflow needs higher-resolution output.

Original Nano Banana is the legacy Gemini 2.5 Flash Image model. It remains useful when 1K output and lower credit cost matter more than the newer model's resolution options.

How to Write a Better Nano Banana Prompt

Clear constraints make generation and editing instructions easier to follow, especially when a source image contains details you need to retain.

Prompt formula

Subject or source image + requested change + details to preserve + style or lighting + output constraints

Lead with the main subject, use direct verbs for the change, and explicitly list anything that should remain untouched. Finish with visual direction and framing.

Product edit

Keep the bottle, label text, proportions, and brand colors unchanged. Replace the background with a pale yellow studio set, add a hard shadow to the right, and frame the product in a centered 4:5 composition.

Names the protected product details before describing the new set and framing.

Portrait edit

Preserve the person's facial features, hair, pose, and camera angle. Change the clothing to a navy work jacket and place the subject on a quiet city street at blue hour with soft cinematic rim light.

Separates identity and pose constraints from wardrobe, location, and lighting changes.

Nano Banana Frequently Asked Questions

Straight answers about the original model, access, pricing, output, editing, and responsible use.

01What is Nano Banana AI?

Nano Banana is the popular name for Google's original Gemini 2.5 Flash Image model. It generates images from text and edits a supplied image through natural-language instructions. This CubistAI page provides third-party access to that original legacy model through the site's existing image-generation service.

02Is Nano Banana made by Google?

Yes. The underlying Gemini 2.5 Flash Image model was developed by Google. CubistAI is an independent third-party interface and is not an official Google product, so the account, credit, and generation experience on this page is provided by CubistAI.

03Is Nano Banana free to use?

Nano Banana uses credits on CubistAI. You must sign in, and each generated image costs 8 credits. A paid subscription is not required, but your account needs enough available credits for the number of outputs you select.

04How do I use Nano Banana online?

Choose Text to Image or Image to Image, enter a prompt, add one reference image when editing, and select an aspect ratio and output count. Sign in and generate, then preview and download the 1K results. Each output uses 8 credits.

05Can Nano Banana generate images and edit photos?

Yes. Text to Image creates a new image from your description. Image to Image combines one uploaded JPG, PNG, or WebP reference with your instructions. For editing, state both the requested change and the identity, layout, lighting, or product details you want preserved.

06What is the difference between Nano Banana and Nano Banana 2?

Original Nano Banana uses Gemini 2.5 Flash Image, produces fixed 1K output, and costs 8 credits per image without a paid-plan requirement. Nano Banana 2 uses Gemini 3.1 Flash Image, offers 1K, 2K, and 4K options, costs more per output, and requires a Starter plan or higher.

07What resolution and aspect ratios does Nano Banana support?

This original Nano Banana page generates fixed 1K output. The interface offers Auto plus 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, and 21:9 aspect ratios. It does not offer a 2K or 4K selector.

08Does Nano Banana add a watermark?

Google states that images generated by its Gemini image models include invisible SynthID to identify AI-generated content. SynthID is not normally a visible overlay, but it means Nano Banana results should not be described as watermark-free.

09Can I use Nano Banana images commercially?

Commercial use depends on the rights attached to your prompt, reference image, subjects, brands, and intended market, as well as the applicable service terms and law. Review CubistAI's terms before publishing or selling a result; this page does not provide a blanket license or legal advice.

10How do I write a good Nano Banana prompt?

Use a concrete structure: name the subject or source image, describe the requested change, list details to preserve, specify style or lighting, and finish with framing or aspect-ratio constraints. For edits, direct instructions such as “keep the face and pose unchanged” are clearer than broad requests such as “make it better.”

Pick a model based on resolution, editing needs, budget, and the type of visual you are creating.
