Nano Banana Pro for Ad Images

Nano Banana Pro is the workhorse image model in Polaris: it generates static ad creative at 2K (15 credits) or 4K (22 credits), outputs PNG, and takes up to 8 reference images via image_input so the product in the shot is recognizably yours — same label, same shape, same color.

What Nano Banana Pro is best at

Product-faithful stills. Feeding several angles of your real product through image_input is what separates a usable ad image from a generic AI render: the model anchors to what your product actually looks like instead of hallucinating a lookalike. That makes it the pick for lifestyle scenes, before/after frames, feature callout graphics, and thumbnail stills to pair with the video ads Polaris generates.

At 15 credits for a 2K image, it is also the cheapest single render in the whole Polaris lineup — an order cheaper per asset than any video clip. Static creative still earns placements in most ecommerce accounts, and the low unit cost means you can batch dozens of concepts without denting the credit pool. See pricing for the math.

When to pick it over the video models

Reach for Nano Banana Pro when the placement calls for a still — carousel cards, catalog-style creative, static retargeting — or when you want to storyboard concepts cheaply before spending video credits. A common pattern: generate a batch of stills to find the scene and angle that feels right, then hand the winner to Kling or Veo as the basis for a moving version of the same idea within your UGC ad mix.

The trade-off is inherent: it is an image model. No motion, no sound, no talking actor. If the concept depends on demonstration or delivery, start with a video model instead. And as with everything generated, a clean render is a starting hypothesis — the market picks winners, not the model.
