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

Flux 2 Lora Gallery
Flux 2 Lora Gallery is a specialized FLUX.2 LoRA workflow for realism. It combines the selected adaptation with FLUX.2’s strong prompt understanding and photorealistic scene construction, concentrating the model on a repeatable production task instead of asking a general image endpoint to infer the workflow from a broad prompt.
Use this route when the input assets and final deliverable match realism exactly. Explain the desired composition and presentation, then state the visual facts that must stay consistent—such as architecture, identity, geometry, branding, or material appearance. The specialization supplies task knowledge, while the brief controls the specific creative result.
Highlights
- Photographic material rendering. Emphasizes believable skin, fabric, surfaces, reflections, and environmental texture.
- Natural illumination. Produces physically plausible light falloff, shadows, highlights, and color response.
- Camera-like presentation. Favors lens, depth-of-field, exposure, and composition cues associated with photography.
- Reduced synthetic appearance. Pushes generated scenes toward grounded detail and away from visibly artificial visual artifacts.
Pricing
| Configuration | Billing unit | Price |

| Base generation | Per request | $0.021 |
When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The project needs this exact generation or editing route | The intended task belongs to video, audio, or 3D media |
| Available references match every required local field | Required source assets or rights are unavailable |
| The brief can specify composition, color, and finish | Output must be deterministic at pixel level |
| Supported dimensions and formats fit final placement | Delivery requires unsupported canvas specifications |
| An asynchronous generated image fits production | A live frame-synchronous response is mandatory |
Prompt Guide
Write a complete visual brief: identify the subject and references, define composition and viewpoint, describe lighting, palette, materials, typography, and finish, then list exact preservation constraints. FLUX.2 Klein does not rely on prompt upsampling, so use clear descriptive sentences rather than sparse keywords.

"prompt": "A photorealistic editorial composition with precise subject placement, controlled lighting, exact colors, and clean typography",
