Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an

Kling 1.6 Elements
elements in the Kling Video lineup is built to combine recurring referenced elements into a new moving composition. The kling video 1.6 elements configuration combines that transformation with the quality and motion profile represented by this exact model version, so teams can choose it deliberately among adjacent family variants. It is useful when the input already establishes part of the creative intent and the model must supply a polished result rather than a generic media conversion, with subject identity, scene logic, visual hierarchy, and the delivery goal kept explicit.
For production work with kwaivgi/kling-video/1.6/elements, begin with the non-negotiable content, then describe the desired change, framing, action, atmosphere, and finishing cues in that order. Separate what must remain recognizable from what may vary, and prefer concrete nouns and observable actions over abstract praise. That structure makes outputs easier to compare across storyboard passes, campaign variants, catalog assets, and other repeatable creative pipelines.
Highlights
Multi-element visual grounding. Uses supplied references as recognizable ingredients in a new moving scene.
Identity-aware composition. Coordinates recurring characters or objects beyond text-only approximation.
Interaction synthesis. Creates motion and spatial relationships instead of static cutout placement.
kling video 1.6 elements consistent asset animation. Preserves important appearance cues while the subjects move. This is the defining creative strength of the kling video 1.6 elements configuration.
Pricing
| Duration | Price per generated clip |
|---|---|
| 5 seconds | $0.2800 |
| 10 seconds | $0.5600 |
Billing follows params.duration * 0.056: multiply generated seconds by the $0.0560 per-second rate.
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.
