Nano Banana Pro - AI Model API and Pricing

Jobs where realism decides the result

Nano Banana Pro is the top of Google's image family on Ugesi. It is the engine behind more tools than any of its siblings. Its edge is photoreal skin and texture. A cheaper model fails there first in a headshot, a fashion image or a product close-up.

It also reads a reference image, a resolution setting and an aspect ratio. The ratios offered are 1:1, 4:5, 16:9 and 9:16. You can frame for a square profile picture, a portrait feed post, a widescreen banner or a vertical story.

Which tool to open for which job

For profile photos without uploading anything, use AI Headshot Generator with the LinkedIn or Studio preset. To put a garment on a person, Virtual Try-On takes your photo plus a clothing image. Full outfit and Top only are the common presets. AI Clothes Changer works similarly, with presets such as Business suit and Winter coat.

For product sellers, AI Image Editor offers Product on white and Remove logo. AI Relight changes the light with presets like Golden hour or Studio key. Expand Image adds room around a shot with More on the sides or More above and below. For a fresh image from text, AI Image Generator has Product on marble, Food shot and Cinematic portrait.

Prompts that use the extra detail

Ask for the things cheaper models blur. Try "Close-up portrait of a woman in her sixties, natural freckles and fine lines, soft window light. Linen shirt, neutral gray background, 4:5." For products: "Leather wallet on dark walnut, visible grain and stitching, single soft key light from the right, 1:1."

When you attach a reference, say plainly what must not change. That might be the face, the logo or the product shape.

Keeping the rate under control

Its only listed limit is price. Out of 41 image models priced per image, this is the most expensive, sitting at the 38-credit ceiling. The easy saving is to explore on Nano Banana 2 at 26 credits or FLUX 2 [max] at 16. Switch to Pro only once the composition is settled.

For images that are mostly text, such as a menu or a poster, pick GPT Image 2 (medium). It is the better tool and, at 14 credits, costs far less.

Worked cost

One image costs 38 credits, about $0.40 at the best pack rate. A set of ten separate headshots or product angles is 380 credits, roughly $4.04. The 750-credit pack for $9 covers that set.
