Nano Banana 2.1 — AI Image Generator and Photo Editor

What is Nano Banana 2.1?

Nano Banana 2.1 is a browser-based AI image studio that generates and edits pictures using the nano-banana-2-1 model, which the site says is accessed through the KIE platform. Users can create images from text descriptions or upload an existing photo and describe changes to its background, outfit, lighting, or objects. Alongside the headline model, the studio exposes several other engines: Nano Banana Pro, GPT Image 2, and a model labeled Freedom for still images, plus Seedance 2.5, 2.0, and 2.0 Mini for video generation.

The site positions the tool at product photography, character and storyboard concepts, social media campaign graphics, posters and packaging, and regional market variations of campaign assets. No company name, country, or launch date is published; the footer shows only a support email and a 2026 copyright notice.

How Nano Banana 2.1 Works

The workflow has three steps. First, describe the image you want, or upload a photo and state what should change and what should be preserved. Second, choose a model, aspect ratio, and resolution — the interface displays the credit cost before generation runs. Third, review the result, refine the prompt if needed, and download.

Generation parameters are comparatively generous: prompts can run to 20,000 characters, up to ten reference images can steer a single generation, output is available at 1K, 2K, and 4K, fourteen aspect ratios are supported, and each run can produce a batch of one to four images. Style presets such as Sticker Pack, Enamel Pin, Plushie, Anime, Watercolor, Vintage Poster, and Product Mockup provide starting points. If a task fails, credits are refunded automatically; completed images consume their credits even if the user immediately regenerates.

Main Features

• Multi-model image generation — text-to-image and image-to-image across Nano Banana 2.1, Nano Banana Pro, GPT Image 2, and Freedom, with per-model credit costs shown up front.
• Reference-image editing — upload a photo and direct changes to background, outfit, lighting, or objects using up to ten reference images.
• High-resolution output — 1K, 2K, and 4K stills across fourteen aspect ratios, in batches of one to four images.
• Companion tools — an image upscaler (to 8K, with JPEG, PNG, and WebP output), a background remover with transparent PNG export, image-to-prompt extraction, and prompt optimization.
• Image-to-video — Seedance 2.5, 2.0, and 2.0 Mini models turn stills into short clips, billed per second of output plus reference-video duration.
• Upfront cost display and refunds — every run shows its credit price before execution, and failed tasks are refunded automatically.

Pricing

Nano Banana 2.1 uses a credit system with a small free tier. New accounts receive 16 one-time starter credits, enough for about five images at the base cost of 3 credits per Nano Banana 1K generation. Professional costs $12.9 per month (discounted from $26) and includes 500 credits — roughly 166 image generations or 50 video generations — with no watermarks and a commercial license. Enterprise costs $59.9 per month (discounted from $120) with 5,000 credits and a commercial license. One-time credit packs that do not auto-renew are also sold, and subscriptions can be cancelled.

Credit costs vary by model and resolution: Nano Banana 1K costs 3 credits; Nano Banana Pro costs 6 credits at 1K/2K and 9 at 4K; GPT Image 2 costs 5, 10, or 15; Freedom 2K/4K costs 6; and Seedance video models bill roughly 4-46 credits per second depending on the model and options.

Common Use Cases

• Product photography — generating and restaging product shots, including regional market variations of the same asset.
• Character and storyboard concepts — drafting visual ideas for stories and pitches before commissioning finished art.
• Social media graphics — campaign visuals in platform-ready aspect ratios.
• Posters and packaging — draft artwork for print-oriented layouts.
• Photo edits — swapping backgrounds, outfits, or lighting on uploaded photos while keeping the subject.

Limitations

The site is explicit about several caveats. Character and product consistency is not guaranteed to match exactly across generations. Image-to-prompt extraction does not recover the original prompt of an image. Commercial use requires a paid plan, and users must hold the rights to uploaded material such as logos and product photos. Free credits are one-time starter credits rather than a recurring allowance, and completed generations consume credits even when the result is immediately regenerated. The operator's identity, country, and track record are not published, so buyers cannot verify who runs the service. The site also advises verifying text, spelling, logos, and factual content before publishing outputs.

Summary

Nano Banana 2.1 packages a current image model lineup into a straightforward web studio with unusually detailed credit pricing and a handful of useful companion tools. Its transparent cost display, automatic refunds, and free starter credits make it easy to try. The undisclosed operator, non-guaranteed consistency, and paywalled commercial rights are the main reasons to test it carefully before committing budget.
