Same prompt, both models

Unedited, at 1 megapixel, with the exact prompt each pair was given. How we ran the test.

Photorealism

What to look for: skin texture, natural light and a believable shallow depth of field.

“Close-up portrait of an elderly fisherman with a weathered face and grey stubble, wearing a yellow raincoat, soft overcast light from a window, shallow depth of field, 85mm photograph”

Text rendering

What to look for: both lines of text spelled correctly and placed on the sign, not floating beside it.

“A vintage enamel sign on a brick wall that reads "FRESH BREAD DAILY" in bold red serif letters, with "since 1962" in smaller script below, morning sunlight”

Prompt adherence

What to look for: exactly three red cubes on the sphere, with the cone on the left and the cylinder on the right.

“Three red cubes stacked on top of a blue sphere, a green cone to the left and a yellow cylinder to the right, on a black and white checkerboard floor, soft studio lighting”

Illustration

What to look for: a consistent watercolor-and-ink style rather than a photo with a filter.

“Children's book illustration of a fox in a knitted scarf reading a book under a large mushroom in light rain, soft watercolor and ink, warm palette”

Complex scene

What to look for: mixed light sources, wet reflections and several subjects in one frame.

“A narrow street in Tokyo at night after rain, neon signs reflecting in puddles, a cyclist with an umbrella passing a lit ramen shop, cinematic”
