Schema

[Core Function] Kling Video O1 is the world's first reasoning-enhanced video model. [Strengths] It performs deep planning over the prompt before generation, delivering best-in-class physical consistency, complex motion logic, and strict adherence to long-form semantics. [Best For] Highly recommended for: complex physical interactions, logically demanding scenes, and prompts requiring deep reasoning. [Limitations] Do NOT use this model if you need multi-shot generation or 15-second durations (it is capped at 10s). [Routing] Route to this model when the prompt involves complex physics, logical sequences, or intricate physical interactions where standard models hallucinate.

Input

Video generation prompt.
Video aspect ratio.
aspect_ratio
Video duration in seconds. In current production behavior, omit this field when `videos` is provided. When using prompt/image-guided generation without `videos`, only `5` and `10` are supported.
5
Optional reference image list. In current production behavior, image-guided generation without `videos` only supports `duration=5` or `duration=10`.
Hint: Drag and drop files, paste from clipboard (Ctrl/Cmd+V), or provide a URL.
Generation mode.
pro
Enable intelligent multi-shot generation.
Required when `multi_shot` is true. Only `intelligence` is supported in the public API.
shot_type
Audio generation switch. Must remain `off` whenever `videos` is provided.
off
Optional reference video list. When provided, `sound` must be `off` and `duration` must be omitted.
Hint: Drag and drop files, paste from clipboard (Ctrl/Cmd+V), or provide a URL.
