Elo ratings from blind side-by-side votes, compared with other image and video models.
Rankings sourced from Artificial Analysis Arena
Image-to-video arena (silent): people pick the better of two clips animated from the same image, without seeing the model names; audio is not judged.
Kling V3 Pro image-to-video: image anchors the first frame, end_image optionally the last, with native audio and multi-shot control.
| Field | Type | Default | Notes |
|---|---|---|---|
prompt | string, required | — | Up to 2,500 characters. |
image | image URL, required | — | First frame. JPEG, PNG, or WebP URL. |
end_image | image URL | — | Optional last frame. |
duration | 3–15 | 5 | Output length in seconds. |
generate_audio | boolean | true | Generate native audio with the clip. |
shot_type | customize / intelligent | customize | customize follows your multi_prompt shot list; intelligent lets the model plan the cuts. |
multi_prompt | object[] | — | Optional list of shots, each with its own prompt and duration. |
You pay for output seconds: $0.168 with audio (the default) and $0.112 without.
| Output | With audio | Without audio |
|---|---|---|
| 3s | $0.504 | $0.336 |
| 5s (default) | $0.84 | $0.56 |
