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

Wan-2.1 Text-to-Video with LoRAs
Wan-2.1 Text-to-Video with LoRAs is the Wan 2.1 adapted workflow for prompt-led video. It models visual appearance and time together so the route’s written direction, source imagery, speech, masks, or structural conditions influence one coherent result rather than a collection of disconnected frames or a generic endpoint response.
Choose this exact route when the available assets and deliverable specifically call for prompt-led video. Identify every subject and source, state the desired action or transformation, then describe camera behavior, pacing, environment, lighting, atmosphere, and preservation requirements; local schema fields handle resolution, duration, seed, and delivery separately from the creative brief.
Highlights
- 2.1 LoRA Written-scene filmmaking. Builds subjects, action, setting, and shot language from a text brief.
- 2.1 LoRA Temporal motion coherence. Maintains plausible movement and interaction across consecutive frames.
- 2.1 LoRA Cinematic camera interpretation. Responds to framing, lens behavior, camera movement, and pacing.
- 2.1 LoRA Scene continuity. Keeps environment and subject logic connected throughout the clip. The route adds a lightweight task adaptation.
Pricing
| Configuration | Billing unit | Price |
|---|---|---|
| Base generation | Per request | $0.75 |
When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The project needs this exact named workflow | The intended task belongs to another media route |
| All required reference or control media is available | Necessary assets or rights are unavailable |
| The brief can state transformation and preservation goals | Output must be deterministic at pixel or frame level |
| Supported duration, resolution, and format fit delivery | Final placement requires unsupported specifications |
| An asynchronous generated result fits production | A live frame-synchronous response is mandatory |
Prompt Guide
Identify the primary subject and every source or condition, state the intended transformation or action, then describe composition, camera or viewpoint, lighting, materials, pacing, atmosphere, and exact preservation requirements. Refer to multiple inputs in their schema order.
{
"prompt": "A precisely directed composition with explicit subject, transformation, camera or viewpoint, lighting, material, and preservation requirements",
"seed": 1,
"loras": [],
"resolution": "480p"
}
