Website: All Image AI

Language: English

FLUX.2 Flash is the low-cost, low-latency FLUX.2 route. It supports text generation and a documented edit operation with as many as four input images; prompt expansion stays disabled so the submitted instruction and quoted credit price remain predictable.

## Model details

- Developer: Black Forest Labs
- Status on All Image AI: Active
- Last verified: 2026-08-25
- Maximum output: 2K
- Modes: Text to Image, Edit Image, Multi-reference
- Reference images: up to 4
- Resolutions: 1K, 2K
- Aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 21:9

## Best for

- Fast FLUX.2 drafts
- Multi-reference composites
- Product and subject edits
- Affordable 2K output

## How to use

1. Generate from text or choose an editing mode.
2. Number every reference in the prompt.
3. State what must remain unchanged.
4. Iterate at 1K and finish the selected result at 2K.

## Settings explained

### Reference Images

Upload up to four; every input is metered upstream, so edit mode adds one visible credit.

### Guidance

The documented default is 2.5. Raise it cautiously for strict constraints.

## Prompt examples

### Fast campaign image

> Minimal running shoe campaign, shoe suspended over red clay, hard side light, energetic diagonal composition

### Four-reference edit

> Use the person from image 1, clothing from image 2, product from image 3 and room from image 4; preserve identity and packaging

## Limitations

- Each edit input adds provider cost
- The interface caps references at four
- Use a Pro or Max tier for the most refined surfaces

## 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 |
| --- | --- |
| 1K | 1 |
| 2K | 2 |

Failed generations cost 0 credits. Catalog availability does not guarantee runtime availability; the workspace reports whether the selected model can run.

## Test results

Testing in progress. No verified benchmark scores have been published for this model.

## Commercial use and image handling

Commercial use is subject to Black Forest Labs' model and service terms.

Uploads are processed by the configured inference service. You can delete a generation from your history.

## Frequently asked questions

### Why does editing cost one extra credit?

The edit endpoint bills processed input images in addition to the generated output.

### Is prompt expansion enabled?

No. It is disabled so literal prompts and per-run cost remain predictable.
