|---|---|---|---|
| prompt* | string | Text prompt for the generated video. | length ≥ 1 · length ≤ 20000 |
| enable_thinking | boolean | Enable enhanced reasoning before generation. | default: false |
| enable_prompt_expansion | boolean | Enable intelligent prompt rewriting. Disabling it can save roughly 20-60 seconds of latency but is likely to degrade generation quality. | default: true |
| aspect_ratio | enum | Output aspect ratio, or adaptive selection. | adaptive | 16:9 | 4:3 | 1:1 | 3:4 | 9:16 · default: "adaptive" |
| resolution | enum | Output video resolution tier. | 480p | 720p | 1080p · default: "1080p" |
| duration | integer | Output duration in seconds. Set to null for smart duration, which lets the model pick a length from the prompt and reference media. | 2 ≤ n ≤ 30 · nullable |
| audio | boolean | Include generated audio. | default: true |
| seed | integer | 0 ≤ n ≤ 2147483647 · nullable | |
