- Status on All Image AI: Active
- Last verified: 2026-08-25

## Best for

- Open-model evaluation
- Detailed illustration
- Broad style exploration
- Reproducible parameter studies

## How to use

1. Start at 1K and 50 steps.
2. Use a concrete negative prompt.
3. Fix a seed before comparing guidance.
4. Move the chosen composition to 2K.

## Settings explained

### Steps

Fifty is the full-model default; reduce it for drafts before increasing resolution.

### Guidance

Five is the documented starting point for prompt adherence.

## Prompt examples

### Fantasy environment

> Terraced city carved into red canyon walls, wind bridges, early morning haze, intricate architectural illustration

### Photographic scene

> Small independent bookstore at dusk, rain on the pavement, warm window light, documentary photograph, 35mm lens

## Limitations

- Slower than distilled models
- Text-to-image only on this page
- 2K output costs four times the pixels of 1K
