The 8 tests, picture by picture

The same description to both, one try each, nothing retouched. Press “Try these words” to make your own.

Test 1 · A poster with real words on it

A poster with words on it: GPT Image is bolder

The description both got

A vintage travel poster with the words "VISIT LISBON" in bold letters at the top, a yellow tram climbing a steep hill at sunset, terracotta rooftops and the river in the distance, mid-century illustration style, flat colors

Winner: GPT Image 2.5 Flare. Both spelled “VISIT LISBON” correctly and both drew the yellow tram, the river and the bridge. GPT Image made a bold poster that fills the frame. Nano Banana Pro's is lovely too, but drawn as a print with a cream border, so it looks smaller.

Test 2 · A card with a name on it

A card with a name on it: a tie

The description both got

A birthday card with the words "Happy 60th, Maria!" in elegant gold letters, surrounded by spring flowers and a small cake with candles, soft watercolor style

GPT Image 2.5 Flare Made in about 12 seconds Tie

A tie. Both wrote “Happy 60th, Maria!” correctly in gold, with spring flowers and a cake. GPT Image made the letters bigger and the card fuller. Nano Banana Pro added a sweet touch: “60” candles on top of the cake. Pick the one you like.

Test 3 · A warm family portrait

A family portrait: a tie

The description both got

A smiling grandmother in her sixties picking ripe tomatoes in a sunlit vegetable garden, straw hat, soft golden evening light, natural skin texture and laugh lines, shallow depth of field, 50mm documentary photo

A tie. Two warm, believable grandmothers in their gardens. GPT Image went closer, with golden evening light behind her. Nano Banana Pro showed more of the garden, with a fence, flowers and gardening gloves. Both look like real photos.

Test 4 · Food that looks good enough to eat

Food that looks good enough to eat: GPT Image

The description both got

A homemade apple pie with a golden lattice crust on a rustic wooden table by a rainy window, a wisp of steam rising, cinnamon sticks and a cup of tea beside it, cozy autumn kitchen, food magazine photo

Winner: GPT Image 2.5 Flare. Both included the rainy window, the tea, the steam and the cinnamon sticks. GPT Image added apples, autumn leaves and a candle, and the whole table feels cozy. Nano Banana Pro's pie is neat but plainer.

Test 5 · A pet portrait

A pet portrait: GPT Image gets closer

The description both got

A fluffy orange cat asleep on a sunny window seat next to a stack of old books and a potted fern, soft morning light, warm and cozy home photo

GPT Image 2.5 Flare Made in about 12 seconds Winner

Winner: GPT Image 2.5 Flare. GPT Image made the sleeping cat the star, curled on a blanket next to a stack of old books and the fern. Nano Banana Pro's cat is lovely, but smaller, in a corner of a room full of plants.

Test 6 · Something that could never happen

Something impossible, a dog on the moon: Nano Banana Pro gets the details

The description both got

A golden retriever wearing a small astronaut helmet sitting on the surface of the moon, the blue Earth rising behind him, footprints in the grey dust, playful, photorealistic

Winner: Nano Banana Pro. Both made a happy golden retriever in a helmet with the Earth behind it. GPT Image's dog is bigger and clearer, but the footprints next to him are boot prints, as if a person had walked there. Nano Banana Pro drew paw prints, a little space suit and a lunar module.

Test 7 · A scene from a dream

A scene from a dream: Nano Banana Pro dazzles

The description both got

A giant whale made of clear glass floating above desert sand dunes at sunrise, sunlight refracting through its body and throwing rainbow patterns on the sand, a lone traveler looking up, photorealistic, wide shot

Winner: Nano Banana Pro. The description asked for sunlight throwing rainbow patterns on the sand. Nano Banana Pro made them bright and everywhere, with rays of light through a detailed glass whale. GPT Image's scene was beautiful but calmer.

Test 8 · A painting in a classic style

A painting in a classic style: Nano Banana Pro looks hand-painted

The description both got

A watercolor painting of a small Tuscan village on a hilltop with cypress trees and a winding road, loose brushstrokes, soft pastel colors, white paper showing through, painted by hand

Winner: Nano Banana Pro. We asked for white paper showing through. Nano Banana Pro painted it like a real watercolor, with loose strokes and white edges. It also signed it with a made-up name, “Giulia Rossi”, that you may want to crop. GPT Image's painting was pretty but looked more like a finished print.

What it costs, in plain words

OpenAI and Google each sell their own plans. In chatmodel, GPT Image 2.5 Flare and Nano Banana Pro are both included in Pro, with every other image model, so you can try the same idea with several of them. See the current prices on the pricing page.

Can you trust the pictures?

Both spelled every word right in our test, but that isn’t guaranteed. Before you print a card or a poster, read every word on it. Look for things you didn’t ask for too: Nano Banana Pro signed its painting with a name that doesn’t exist. And remember the pictures are made up: don’t use them to show something that really happened.

How we tested

We wrote 8 descriptions of the pictures people actually make: a family portrait, food, a poster, a birthday card, a pet, and a few impossible scenes. Both models got exactly the same words, one try each, and we kept the first picture without retouching it. We judged how well each picture followed the description and how good it would look printed or shared.

One try each is a small test: ask again and you’ll get a different picture. Treat the winners as a guide, and try your own idea with both. If you’re choosing between Google’s two versions, see Nano Banana Pro vs Nano Banana 2.
