# 15 AI image models, one prompt: what each model drew

> We gave 15 AI image models one long prompt with 15 hard details. See which details each model drew, from the crystal city to the figure walking upside down.

Source: https://nodaro.ai/docs/compare/ai-image-models-same-prompt

We gave **15 AI image models** the same long prompt. It describes a woman in a white dress at the edge of a city inside a giant crystal, under a red moon, with whales in the sky and a tiny figure walking upside down. Every model drew the woman, the moon and the city lights. The models split on the hard details: only four drew the figure walking upside down, and none drew water flowing upward.

- Models: 15
- Prompt: 1
- Details checked: 15
- Aspect ratio: 16:9
- Upside-down figure: 4 of 15
- Upward waterfalls: 0 of 15

## The test

Every model got the same prompt and a 16:9 aspect ratio, and we asked each model for 2K. Models without a 2K setting made their usual size, so the images range from 1280×720 to 2752×1536. Each model made one image, its first take. We ran the test in September 2026.

This is the prompt, word for word:

```
A lone woman in an elegant flowing white couture dress stands at the edge of an impossible city built inside a colossal transparent crystal suspended above a dark ocean.

Inside the crystal, an entire surreal metropolis stretches into the distance: monumental glass towers bend and curve like liquid, upside-down buildings hang from the sky, enormous translucent staircases climb into clouds, and tiny waterfalls flow upward between floating islands.

A gigantic crimson-red moon fills almost half the sky behind the crystal, partially obscured by dramatic storm clouds.

Thousands of tiny warm lights glow throughout the city, creating an extraordinary sense of scale.

The woman stands on a narrow mirror-like black platform extending over the void. Her dress is caught by a strong wind, with long pieces of fabric flowing dramatically behind her.

Below the transparent floor, enormous luminous blue whales appear to be swimming slowly through the night sky instead of water.

Rain falls outside the crystal but stops perfectly at its surface. Individual droplets cover the exterior, refracting and distorting fragments of the city behind them.

The crystal creates complex optical phenomena: refraction, internal reflections, chromatic dispersion, subtle rainbow caustics, distorted duplicates of the woman, and fractured reflections of the red moon.

Far in the distance, a tiny human figure walks upside down across the underside of one of the floating islands.

The image should feel enormous, mysterious, beautiful, physically impossible, and strangely believable.

Extreme contrast of scale.
Deep spatial layering from foreground to extreme distance.
Intricate transparent materials.
Realistic human proportions.
Rich micro-detail.
Atmospheric depth.
Volumetric light passing through crystal and mist.
Complex reflections and refractions.
Physically convincing surfaces despite the impossible environment.

The composition should immediately make the viewer stop and examine the image to understand what they are seeing.
```

We split the prompt into 15 details and checked every image for each one.

## Which details the models drew

| # | Detail in the prompt | Drawn | Partly | Missing |
| --- | --- | --- | --- | --- |
| 1 | A woman in a white couture dress, caught by the wind | 15 | 0 | 0 |
| 2 | A narrow, mirror-like black platform | 14 | 1 | 0 |
| 3 | A colossal crystal above a dark ocean | 10 | 4 | 1 |
| 4 | The city inside the crystal | 13 | 1 | 1 |
| 5 | Glass towers that bend like liquid | 8 | 3 | 4 |
| 6 | Upside-down buildings hanging from the sky | 7 | 4 | 4 |
| 7 | Translucent staircases climbing into clouds | 11 | 1 | 3 |
| 8 | Waterfalls flowing upward | 0 | 13 | 2 |
| 9 | A giant crimson moon behind the crystal | 15 | 0 | 0 |
| 10 | Thousands of tiny warm lights | 15 | 0 | 0 |
| 11 | Luminous blue whales below the floor | 12 | 3 | 0 |
| 12 | Rain that stops at the crystal's surface | 9 | 3 | 3 |
| 13 | Rainbow light in the crystal | 6 | 4 | 5 |
| 14 | Distorted copies of the woman or the moon | 5 | 6 | 4 |
| 15 | A tiny figure walking upside down under an island | 4 | 1 | 10 |

In row 8, Partly means that the image has waterfalls, but they fall down, as waterfalls usually do.

## What we saw

  
**Every model drew the main scene.** 
All 15 drew the woman in the wind, the giant red moon and the city lights. 14 put her on a narrow black platform, and 13 put the city inside the crystal.
  

  
**No model drew water flowing upward.** 
    13 images have waterfalls, and every one of them falls down. The two Grok models drew no waterfalls at all.
  

  
**Four models drew the figure walking upside down.** 
Nano Banana 2, Nano Banana 2 Lite, Flux 2 Flex and Grok Imagine 2 drew it. Flux 2 Pro hung a figure from the edge of an island instead.
  

  
**The optical effects split the models.** 
Six drew rainbow light in the crystal. Five drew distorted copies. Seedream 5 Pro and Grok Imagine 2 drew a ghost of the woman, Nano Banana 2 Lite and Flux 2 Pro a second moon, and Grok Imagine broken reflections of the moon.
  

  
**Nine kept the rain outside the glass.** 
In these images the rain falls outside the crystal or beads on its surface, and the city inside stays dry. Flux 2 Klein, Flux Kontext Pro and Flux Kontext Max let the rain fall everywhere.
  

  
**Ten models floated the crystal above the sea.** 
Seedream 5 Lite set it on the water, and Flux Kontext Max made it a tower that rises from the sea. Flux 2 Klein drew a glass floor instead, with the city on an island.

## How we read the images

We checked every image, with full-size crops wherever a detail was small. A detail counts as drawn when it is clearly there. It counts as partly drawn when it is there but changed, for example a crystal that sits on the sea instead of floating above it. It counts as missing when we could not find it. For the waterfalls, we judged the direction from the shape of the water and its spray.

The prices are today's prices for the same settings, and each model's page lists all of its prices. We also ran two models that are no longer in Nodaro's model catalog, so this page does not show them.

This is one image per model, from one prompt. Another image from the same prompt can differ. Read the checklist as what each model drew this time, not as a ranking of the models.

## Run the same test in Nodaro

Connect one [Text](https://nodaro.ai/docs/nodes/automate/text) node with your prompt to several [Generate Image](https://nodaro.ai/docs/nodes/image/generate-image) nodes. Choose a different model in each Generate Image node, and run the workflow. Each node shows its price on its **Run** button before it runs. To animate the image you like best, connect it to [Generate Video](https://nodaro.ai/docs/nodes/video/generate-video) nodes, as we did in the [video comparison](https://nodaro.ai/docs/compare/ai-video-models-same-prompt).

## Frequently asked questions

### Which AI image model follows a long, detailed prompt best?

No model drew every detail of this prompt, and one image per model is not a ranking. All 15 drew the main scene. The split came on small or unusual details: four models drew the tiny figure walking upside down, Nano Banana 2, Nano Banana 2 Lite, Flux 2 Flex and Grok Imagine 2.

### Which details do AI image models skip in a long prompt?

In this test, the missed details were unusual, tiny or optical: water flowing upward, a small figure walking upside down in the distance, and distorted copies of the woman in the glass. Common things, such as the woman, the moon and the city lights, appeared in every image.

### Can an AI image model draw a waterfall flowing upward?

None of the 15 models did in this test. Thirteen drew waterfalls, and every one of them falls down. The two Grok models drew no waterfalls at all.

### How much does an image cost on these models?

At today's prices and the settings we used, an image costs from 4 credits with Flux 2 Klein to 77 credits with Flux 2 Max. Every model's price is in its caption on this page.

### Can I compare image models side by side in Nodaro?

Yes. Connect one Text node with your prompt to several Generate Image nodes, choose a different model in each node, and run the workflow. Each node shows its price on its Run button before it runs.
