Output Schema
| Field | Type | Description |
|---|---|---|
id | string | Unique identifier for the generation task |
status | string | Task status: pending, running, completed, failed, timeout |
model | string | Model used for the generation |
outputs | array | Array of output items |
outputs[].url | string | URL of the generated artifact |
outputs[].content_type | string | MIME type (e.g. image/png, video/mp4) |
error | object | null | Error details if failed, null on success |

error.message | string | Human-readable error description |
Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read
outputsfrom the completed response

FLUX.1 [dev] Redux
FLUX.1 [dev] Redux adds Redux reference-image guidance to the open development model, extracting high-level aesthetic and compositional cues from a source and using them to generate a related visual. It offers a research-friendly way to study reference conditioning and build visual-variation tools around FLUX.1.
Use references that clearly express the palette, layout, texture, or mood worth transferring. This model fits mood-board expansion, source-related concept generation, and custom reference pipelines where creators want new content that remains aesthetically connected to an existing image.
Highlights
- Open reference conditioning. Exposes Redux-style visual guidance through the development model.
- Composition and mood transfer. Carries high-level structure, palette, texture, and atmosphere from a source.
- Fresh visual derivation. Creates related imagery without performing a pixel-level copy.
- Custom reference experimentation. Supports local research and adapted reference-to-image workflows.

When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The model's named workflow matches the source material and intended output | A different input modality or model route is required |
| A managed asynchronous result is suitable for the production pipeline | A synchronous, interactive editor is essential |
| The documented controls cover the required duration, framing, or format | The project needs controls outside this endpoint's schema |
| Creative iteration benefits from a repeatable request structure | Exact deterministic pixels, frames, geometry, or samples are mandatory |
| A finished downloadable media asset is the desired deliverable | Editable source layers or a native project file are required |
Prompt Guide
For image-conditioned generation, state the intended result first, then add the subject or source treatment, progression, style, and delivery constraints. Keep one creative variable per phrase, use the documented field names for controls, and change one setting at a time when comparing results.
