Image model
Create or transform one image with a clear 3-credit quote
Nano Banana is a formal image model in WAN3. Choose text-to-image for a new composition or image-to-image with exactly one source image, then select the aspect ratio and output format before submitting.
01
Choose text-to-image or one-image transformation
Text-to-image accepts a prompt without source media. Image-to-image requires exactly one JPEG, PNG or WebP source image up to 30 MB; additional inputs are rejected before generation.
02
Select ratio and output format
Nano Banana supports Auto plus common square, portrait, landscape and cinematic aspect ratios. Choose PNG or JPG; each task expects exactly one finished image.
03
Pay 3 credits per image task
Both text-to-image and image-to-image cost 3 credits per task. Failed accepted tasks are refunded once, while successful output is stored by WAN3 before the owner-only download is enabled.
04
Know the launch boundary
The launch contract creates one image per task and does not expose batch generation. Status, price, failure and refund facts remain visible in the mixed private Creations history.
