Wan 3.0 Pro Prime Text to Video
alibaba/wan/3.0/pro/prime/text-to-videoWan 3.0 Pro Prime by Alibaba turns a text prompt into a video of up to 30 seconds at 30fps, with native dialogue, music, and sound effects, upscaled to 1080p, 2K, or 4K.

Playground
Input
Text prompt for the generated video.
Output duration in seconds (2-30), or `auto` to let the model pick a length from the prompt and inputs. `auto` is pre-authorized at 30 seconds and billed on the actual output length.
Output aspect ratio. Defaults to 16:9.
Output resolution tier after FlashVSR super-resolution.
Advanced settings
Generate a synchronized audio track. Pricing is the same either way.
Random seed (0-2147483647) for reproducible results. Omit for a random seed; the same seed may still produce slightly different results. Range: 0 to 2147483647.

Wan 3.0 Pro Prime Text to Video
Write a scene and get back a 2–30 second, 30fps clip with matching dialogue, music, and sound effects. No images or reference media are needed. Pro runs the same Wan 3.0 Prime model, then upscales the result with FlashVSR, so output comes back at 1080p, 2K, or 4K. For 480p or 720p use the non-Pro endpoints.
Pro Prime is the faster Wan 3.0 Pro tier: the same inputs and output quality as Wan 3.0 Pro, with significantly shorter end-to-end generation time and a higher per-second rate. Use Wan 3.0 Pro for batch or background jobs where turnaround does not matter.
Fields
| Field | Type | Default | Notes |
|---|---|---|---|
prompt | string, required | — | Up to 5,000 characters. |
duration | 2–30 or auto | 5 | auto lets the model pick the length. |
resolution | 1080p / 2k / 4k | 1080p | Output tier after FlashVSR super-resolution; sets the per-second rate. |
aspect_ratio | adaptive / 16:9 / 4:3 / 1:1 / 3:4 / 9:16 | adaptive | adaptive follows the prompt and inputs. |
generate_audio | boolean | true | Native dialogue, music, and effects. Same price on or off. |
seed | integer 0–2147483647 | random | Fix it to compare prompt changes. |
Billing
You pay for output seconds only: $0.26 at 1080p, $0.28 at 2K, $0.31 at 4K. Input images, audio, and video are not metered.
| Output | Billed | 1080p | 2K | 4K |
|---|---|---|---|---|
| 2s | 2s | $0.52 | $0.56 | $0.62 |
| 5s (default) | 5s | $1.30 | $1.40 | $1.55 |
| 10s | 10s | $2.60 | $2.80 | $3.10 |
| 30s | 30s | $7.80 | $8.40 | $9.30 |
With duration: "auto" the run is pre-authorized at 30 seconds, then settled on the length that was actually generated. Failed runs are not charged. Output files are copied to SandBase storage and the returned URL stays valid for 7 days; download anything you need to keep.
Prompting
- Cover subject, action, setting, camera, light, and sound in one or two sentences each.
- Spell out camera timing, e.g. “holds for two seconds, then cranes up over the rooftops”.
- Quote dialogue and say who speaks it.
At night a kitten trots along a wet rooftop; neon signs flicker across the city behind it. Low tracking shot that rises as it leaps a gap, soft rain and distant traffic.
Limits
- This endpoint accepts no media inputs. To animate a picture use image-to-video; to steer with references use reference-to-video.
