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

Kling Image V3
Kling Image V3 is a straightforward text-to-image endpoint for turning a detailed prompt into an original visual. The prompt accepts up to 2,500 characters, allowing the brief to develop atmosphere, materials, lighting, camera language, and subject detail beyond a short caption.
Its delivery controls cover ten aspect ratios, two resolution levels, and both PNG and JPEG. That combination lets one prompt be explored for panoramic, square, editorial, or mobile placements while keeping the output choice explicit.
Highlights
Long-form art direction. A 2,500-character prompt field supports richer scene and style descriptions.
Ten framing presets. Move from 21:9 panorama to 9:16 vertical, including square and several photographic ratios.
Standard or high resolution. Select 1K for routine iterations or 2K when the image needs a larger render.
Practical export choice. Return the generated artwork as PNG or JPEG.

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.
