**Model ID:** `kling-video-o1-reference-to-video`

**Kling O1 - Reference to Video** is a **multimodal video generation model** designed for reference-guided video synthesis. It excels in transforming reference videos or images into new sequences while preserving motion dynamics, camera movements, and visual styles for consistent outputs.

Some other noteworthy features of Kling O1 - Reference to Video include image-to-video transformations, multi-reference image conditioning (up to 7 images), scene extension with continuity, and support for start/end frames or keyframes.

| 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-o1-reference-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.

  <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.
