Generation defaults to model: "nano-banana-2", resolution: "standard", and num_images: 1. Add settings to your prompt or product-reference request:

​
Choose the image shape

Use aspect_ratio for the composition you need. Nano Banana 2 supports common ratios including 1:1, 3:4, 4:5, 2:3, 9:16, 16:9, 4:3, 3:2, 5:4, and 21:9. resolution controls quality: standard or high. Exact dimensions depend on the model and proportions; read them from the completed result. See the generation reference for supported models and the request settings for other operations.

​
Request more than one result

num_images counts output images, independently of how many garments you supply. The request above returns two entries in jobs. Save and check each ID independently; results can finish at different times. Generate accepts one to eight outputs, subject to your account limits. More outputs or higher quality can change credit use. Use an idempotency key to retry the same submission safely. Starting another intentional generation requires a new key.

​
Continue editing

On completion, send result.id to edit, inpaint, upscale, or image-to-video. Each operation returns new IDs to track. You do not need to select or manage Studio versions.
