Kling Video O1

Kling Video O1 (Omni One) is Kuaishou's industry-first unified multimodal video model that merges video generation and editing into a single engine. Integrating text-to-video, image-to-video, element referencing, localized inpainting, and video restyling, it supports referencing up to 7 subjects simultaneously to lock character and prop consistency. Creators can perform conversational video editing via natural language prompts—ideal for advertising, VFX, and end-to-end film production.

Code Examples

Image and video generation uses a two-step async flow: submit a task to get task_id, then poll via query task result; the response includes status and result ([] while processing; on SUCCEEDED, result holds resources and costUSD is present). The examples below use the same task_id across both steps.

1. Submit Task

Send a generation request to the submit endpoint.

POST/v1/task/submit/kwaivgi/kling-video-o1

curl --fail-with-body --connect-timeout 10 --max-time 60 \
  -X POST "https://api.icreat.ai/v1/task/submit/kwaivgi/kling-video-o1" \
  -H "Authorization: Bearer ${ICREAT_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Make the person in <<<image_1>>> wave at the camera",
    "image_list": [
      {
        "image_url": "https://example.com/first-frame.png"
      }
    ],
    "mode": "pro",
    "aspect_ratio": "16:9",
    "duration": "5"
  }'

2. Query Task Result (Poll)

Use the task_id from submit to poll progress (repeat until terminal). The response includes status and result: result is [] while processing; on SUCCEEDED, result holds resources and costUSD is included; FAILED means the task failed.

POST/v1/task/result

curl --fail-with-body --connect-timeout 10 --max-time 60 \
  -X POST "https://api.icreat.ai/v1/task/result" \
  -H "Authorization: Bearer ${ICREAT_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{"task_id": "task-xxx"}'

# kwaivgi/kling-video-o1

> Kling Video O1 (Omni One) is Kuaishou's industry-first unified multimodal video model that merges video generation and editing into a single engine.

## Overview

Use the iCreat two-step async task API: submit a generation request, then poll the query task result endpoint; on success read resources from `result` (includes `costUSD`).

## API Info

- **Base URL**：`https://api.icreat.ai`
- **Submit endpoint (POST)**：`/v1/task/submit/kwaivgi/kling-video-o1`
- **Query result endpoint (POST)**：`/v1/task/result`
- **Model ID**：`kwaivgi/kling-video-o1`
- **Auth**：`Authorization: Bearer ${ICREAT_API_KEY}`

## Call Flow

1. **Submit**: POST submit path with body per Input Notes; response `{ "task_id": "..." }`
2. **Query result**: POST `/v1/task/result` with `{ "task_id": "..." }`; response includes `status` and `result` (`[]` while processing); on `SUCCEEDED`, `result` holds resources and `costUSD` is present; read `url` or `download_url` when `type` is `Video`

### Input Notes

- Request body uses top-level flat fields
- Required: `element_id`, `video_url`
- Optional: `negative_prompt`, `multi_shot`, `image_list`, `element_list`, `video_list`, `sound`, `mode`, `aspect_ratio`, `duration`, `watermark_info`, `refer_type`, `keep_original_sound`, `enabled`
- `negative_prompt` (optional): Negative prompt describing content that should not appear in the video
- `multi_shot` (optional): Whether to enable multi-shot generation
- `image_list` (optional): List of image assets
- `element_list` (optional): List of subject assets
- `video_list` (optional): List of video assets
- `sound` (optional): Whether to generate audio. Supported values: `on`, `off`. Must be `off` when `video_list` is provided
- `mode` (optional): Generation mode. Supported values: `std`, `pro`, `4k`. `std` corresponds to 720p and `pro` corresponds to 1080p
- `aspect_ratio` (optional): Output aspect ratio. Supported values: `16:9`, `9:16`, `1:1`
- `duration` (optional): Video duration in seconds
- `watermark_info` (optional): Watermark configuration. Currently, only the `enabled` field is supported
- `element_id` (required): ID of a subject in the subject library
- `refer_type` (optional): Video reference type. Supported values: `feature`, `base`
- `keep_original_sound` (optional): Whether to preserve the original video audio. Supported values: `yes`, `no`
- `enabled` (optional): Whether to enable the watermark

### Output Notes

- Poll: read `status`; `result` is `[]` while processing
- Success: `result` is `[{ "type": "Video", "url": "...", "download_url": "..." }]` plus `costUSD`

## Notes

- Use the same `task_id` across both steps; `result` is `[]` while processing — keep polling
- `FAILED` is terminal — check request parameters or reference media
