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 2 Max Edit
Flux 2 Max Edit belongs at the top-tier revision of approved imagery stage of a visual workflow. Rather than treating the model as an isolated demonstration, teams can place it inside briefing, review, selection, and handoff practices where the workflow keeps an existing asset at the center of discussion while giving art directors room to request ambitious changes before final sign-off. This positioning clarifies why the model earns a place in a real creative pipeline and what kind of decision it helps people make.
A practical use of Flux 2 Max Edit is premium product updates, hero-image localization, difficult compositing briefs, and campaign revisions where re-shooting is undesirable. Begin by agreeing on the creative objective and review criteria, prepare only the source material needed for that objective, and compare results against audience, brand, editorial, and production needs. Technical request choices remain documented below so the prose can stay focused on planning and creative value.
Highlights
Semantic instruction following. Understands requested changes at the level of objects, attributes, relationships, and scene intent.
Identity retention. Keeps important people, products, and branded details recognizable through iterative revisions.
Context-aware integration. Matches new content to source lighting, perspective, materials, and composition.
Iterative edit stability. Supports successive creative changes without unnecessarily redesigning unaffected image content. The Max edition emphasizes the family's highest visual fidelity, typography, prompt accuracy, and edit preservation.

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 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.
