How do reference edits work?
Upload an image and describe the change. In this test, Nano Banana 2.1 changed the background and pedestal from cream to mint while retaining the blue bottle, silver cap and MINT 01 label.
“Keep the blue bottle, silver cap and exact "MINT 01" label from the reference image. Change only the background and pedestal to a soft pale mint studio scene with diffuse window light. Do not add props or extra text.”Start a reference edit

What is Nano Banana 2.1?
Nano Banana 2.1 is Google’s Gemini image generation and editing model. OpenBanana is an independent image workspace that accesses it through APIMart’s 2.1 Ext route.
Can I edit an existing image?
Yes. Attach one PNG, JPG or WebP reference under 5 MB and describe your changes. You can also use a completed image from your own history as the next reference. Review labels, faces and other details before using the output.
How many credits does an image use?
One 1K image uses 10 credits, a 2K image uses 20, and a 4K image uses 30. Each request produces one image. The studio shows the credit cost before you submit.
What happens if generation fails?
A confirmed provider failure returns the reserved credits. If a submission or status check is interrupted, the saved task stays available to check again.
Are reference images published?
No. References are sent to APIMart to complete your request, and are not published in a gallery. Account history is visible only to its owner.
How long do image links last?
Image download links are temporary. Your completed task shows the available download window. Save a copy to your device when the image is ready.
