KLING V1.6 Text-to-Video is an AI text-to-video generation model developed by the Kuaishou AI team. It can transform text descriptions into dynamic 5-second 720p videos, delivering high-quality visual output with enhanced motion and semantic understanding capabilities.
This is an asynchronous API and will only return the asynchronous task’s task_id. You should use this task_id to request the Get Task Result API to retrieve the video generation result.

​
Request Headers

​
Content-Type
string
required
Enum value: application/json
​
Authorization
string
required
Bearer authentication format: Bearer {{API Key}}.

​
Request Body

​
mode
string
Video generation mode.Supported:
  • Standard: Fast generation, lower cost, generates 720p videos.
Default value: Standard.
​
prompt
string
required
The prompt text used to guide generation.Value range: 1 <= x <= 2000.
​
negative_prompt
string
Negative prompt, used to indicate content that the model should avoid generating.Value range: 0 <= x <= 2000.
​
duration
integer
Duration of the generated video (in seconds). Default value: 5.
Optional values: 5, 10
​
guidance_scale
float
Guidance strength parameter, which controls how closely the generated content adheres to the prompt.Value range: 0 <= x <= 1. Default value: 0.5.

​
Response

​
task_id
string
required
The task_id of the asynchronous task. You should use this task_id to request the Get Task Result API to obtain the generation result.
