Language: English

Nucleus Image is an efficient text-to-image model from NucleusAI. It exposes a broad steps and guidance range while keeping the current 1K run at one credit, which makes it practical for inexpensive seeded experiments and prompt exploration.

## Model details

- Developer: NucleusAI
- Status on All Image AI: Active
- Last verified: 2026-08-25
- Maximum output: 1K
- Modes: Text to Image
- Reference images: not supported
- Resolutions: 1K
- Aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3

## Best for

- Low-cost prompt exploration
- Seeded comparisons
- Illustration concepts
- Negative-prompt experiments

## How to use

1. Write a clear subject and composition.
2. Add visible defects to Negative Prompt.
3. Fix a seed for comparisons.
4. Change one parameter at a time.

## Settings explained

### Steps

Fifty is the documented default; lower values are useful for quick prompt comparisons.

### Guidance

Eight is the default. Change it gradually while holding the seed fixed.

## Prompt examples

### Editorial illustration

> Editorial illustration of a city growing around an old tree, layered paper textures, restrained green and rust palette

### Atmospheric scene

> Small observatory above a sea of clouds before dawn, soft blue hour, tiny warm windows, cinematic wide composition

## Limitations

- Text-to-image only
- Two outputs per run maximum
- One exposed resolution tier

## Pricing and credits

Credits for one image at default quality and mode. Resolution, quality, reference inputs, edit mode and output count can change the total. Check the Generate button before submitting.

| Resolution | Credits / image |
