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. GPT Image made a bold poster with the yellow tram, the rooftops and the river all in view. Grok made the words so big they take the top third, and the tram is cut off at the bottom, even if it got a nice real detail: “M. MONIZ 28” on the tram's sign.

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 card with a name on it, made with Grok Imagine Image 2.0

A tie. Both wrote “Happy 60th, Maria!” correctly in gold, with spring flowers and a cake with candles. GPT Image made a square card with bigger letters. Grok made a tall card shape, like one you'd fold and stand up. Pick the one you like.

Test 3 · A warm family portrait

A family portrait: Grok comes in closer and warmer

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

Winner: Grok Imagine Image 2.0. Both grandmothers look real. Grok came in close, with warm light, laugh lines and a big natural smile as she holds a ripe tomato. GPT Image's portrait is lovely too, with the sunset behind her, but a little further away.

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. GPT Image put in everything we asked for: the rainy window, the steam, the cinnamon sticks and a cup of tea, plus apples and autumn leaves. Grok's pie looks delicious by a rainy window, but there's no cup of tea.

Test 5 · A pet portrait

A pet portrait: GPT Image makes the cat the star

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 big and fluffy on a cushioned window seat, next to old books and the fern. Grok's cat is sweet, curled on a blanket on a wooden ledge, but smaller in the picture.

Test 6 · Something that could never happen

Something impossible, a dog on the moon: GPT Image

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: GPT Image 2.5 Flare. GPT Image made a happy golden retriever right in the middle, tongue out, with the Earth behind him. The footprints next to him are boot prints, as if a person had walked there. Grok pushed the dog against the left edge and cut off part of his helmet.

Test 7 · A scene from a dream

A scene from a dream: GPT Image fits it all in

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: GPT Image 2.5 Flare. GPT Image showed the whole glass whale above the dunes at sunrise, with rainbow patterns on the sand. Grok's whale is beautiful, but its head runs off the right edge of the picture.

Test 8 · A painting in a classic style

A painting in a classic style: a tie

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

A tie. Both look like real watercolors, with cypress trees, a winding road and white paper at the edges. GPT Image's is lighter and airier. Grok's village is more detailed, with a patch of lavender at the bottom. Pick the one you like.

What it costs, in plain words

OpenAI and xAI each sell their own plans. In chatmodel, GPT Image 2.5 Flare and Grok Imagine Image 2.0 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. Check the edges too: Grok sometimes cuts off part of the subject, and if that happens, just ask again. 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. To see how they do against Google’s and other models, see the best AI image generator test.
