Website: All Image AI

Language: English

FLUX1.1 Pro is the production member of the FLUX1 line. It is a strong choice for realistic light, surface texture and product imagery when you want the established Pro look without the fixed native 2K constraint of the Ultra endpoint.

## Model details

- Status on All Image AI: Active
- Last verified: 2026-08-25
- Maximum output: 2K
- Modes: Text to Image
- Reference images: not supported

- Aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 21:9

## Best for

- Product and material photography
- Cinematic scenes
- Natural portraits
- 2K final renders

## How to use

1. Describe subject, material, light and camera treatment.
2. Start at 1K.
3. Fix the seed before comparing parameters.
4. Render only the selected direction at 2K.

## Settings explained

### Safety Tolerance

Keep the default for ordinary commercial work.

### Resolution

Use 1K for iteration; 2K processes about four times as many square pixels.

## Prompt examples

### Material study

> Brushed titanium headphones on dark volcanic stone, precise specular highlights, single strip light, premium product photograph

### Cinematic scene

> Rainy tram stop at midnight, wet asphalt reflections, one warm practical light, restrained teal film grade, 35mm lens

## Limitations

- Text-to-image only on this endpoint
- 2K costs by processed megapixel
- Newer FLUX.2 routes handle complex edits better
