Cheapest Nano Banana Pro API: price per image compared (Nov 2026)

Nano Banana Pro price per image

Nano Banana Pro generates and edits images, up to 4K. The model page is Nano Banana Pro. A request takes up to 14 reference images and up to 4 images per call in these aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2 and 2:3.

The price is per image, so a request with n set to 4 at 2K costs four times the 2K price: $0.16. The aspect ratio does not change the price.

The rest of the Nano Banana family

If Pro is more than your task needs, the cheaper siblings are on the same API and use the same request shape.

Against Higgsfield, Nano Banana 2 saves 59% at 1K, 69% at 2K and 72% at 4K, and Nano Banana saves 38%.

Which size to ask for

At $0.04, 1K and 2K cost the same, so asking for the smaller file saves nothing. 4K costs $0.08, twice as much. A sensible habit is to iterate on a prompt at 2K and ask for 4K only for the final file, such as a print, a hero image or a crop. A batch of 100 images at 2K is $4.00 on VidLab and $9.80 at Higgsfield's Plus rate.

Call it

Estimate, then generate. The key comes from the environment.

curl -s -X POST https://vidlab.ai/v1/estimate \
  -H "Content-Type: application/json" \
  -d '{"model":"nano-banana-pro","input":{"resolution":"2k","n":1}}'

curl -s -X POST https://vidlab.ai/v1/generations \
  -H "Authorization: Bearer $VIDLAB_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{"model":"nano-banana-pro","input":{"prompt":"A ceramic mug on a linen cloth, soft window light","resolution":"2k","aspect_ratio":"1:1"},"max_price_usd":0.04}'

Images usually take seconds to a minute. Poll GET /v1/generations/{id} until it succeeds. To edit a picture, add its public https URL to images. The output links are signed and last 6 hours, so copy the files you want to keep. The quickstart shows the polling loop in Node and Python.
