**Model ID:** `kling-video-v2-6-pro-image-to-video`

Kling 2.6 Pro - Image to Video is a **Diffusion model** designed for generating short video clips from a static input image. It excels in producing motion with visual consistency from the reference image, along with optional synchronized native audio including sound effects and dialogue.

Some other noteworthy features of Kling 2.6 Pro - Image to Video include support for 1080p resolution in 16:9, 9:16, or 1:1 aspect ratios, and clip durations of 5 or 10 seconds.

| Metric             | Value   |
| ------------------ | ------- |
| Parameter Count    | Unknown |
| Mixture of Experts | Unknown |
| Context Length     | Unknown |
| Multilingual       | No      |
| Quantized\*        | Unknown |

\**Quantization is specific to the inference provider and the model may be offered with different quantization levels by other providers.*

## Example request

<Tip>
  Use the [Workbench](https://www.oxen.ai/ai/workbench?model=kling-video-v2-6-pro-image-to-video) as a request builder: configure parameters for this model in the UI, then open the **API** tab to copy the exact cURL or Python call.

<Tabs>
  <Tab title="Sync">
    This blocks until the video is ready (typically 5-15 minutes). Prefer **Async** or **Async with SSE** for anything beyond quick experimentation.

    See the [video generation reference](/inference-api/reference/video_generation) for more details.
