Nano Banana 2.1 is an image generation and editing model from Google, released in October 2026 as an update to Nano Banana 2. On LubanAI it runs in the AI product photo workspace and the AI image generator at 1K, 2K or 4K.

Nano Banana 2 is Google's name for the Gemini 3.1 Flash Image model, and Nano Banana 2.1 is its updated version. On LubanAI, Nano Banana 2.1 runs in the AI product photo workspace and the AI image generator with your LubanAI account and credits, so no separate Google account is needed. Upload a product photo, describe the scene you want, and download the finished image.

In the AI product photo workspace, each generation takes up to 5 images: at least one product photo plus optional references for the model, pose, background or scene. With improved multi-image editing, Nano Banana 2.1 blends them into a single image, which suits listing photos that need the same model or setting across a product range. Clear, evenly lit photos give the most accurate product details.

You need a free LubanAI account and credits. Each Nano Banana 2.1 generation uses credits, which you can add at any time through a subscription or a one-time credit pack whose credits never expire. No API key or separate account with the model developer is needed.

Signed-in users get 10 free credits every day, reset at midnight UTC. With a verified email, these daily credits can pay for Nano Banana 2.1 at any resolution the balance covers. Accounts with a subscription or credit pack balance pay from that balance, and daily credits apply once it reaches zero. Credit packs start with the Starter pack at $0.99 for 100 credits. The generate button shows the exact cost before you submit.

Nano Banana 2.1 starts at 7 credits per image for a 1:1 image with one reference image. Higher resolutions cost more. The exact amount appears on the generate button before you submit.

Nano Banana 2.1 offers 1K, 2K and 4K in a range of aspect ratios. 1K uses the fewest credits and suits drafts and quick tests. 2K fits most listing images and product pages. Choose 4K for print, large banners or heavy cropping; it uses the most credits and produces larger files, which may need compressing before you upload them to a marketplace.

Yes. Images you create with this model can be used commercially, including in product listings, ads, store banners and social media posts. No attribution is required on paid plans or credit packs; free-plan outputs require attribution to LubanAI. See our Terms of Service for details.
