1080p	5s	$0.40	$0.80
1080p	10s	$0.60	$1.20

Billing Rules

Resolution multiplier: 720p (1280720 / 7201280) = 1×, 1080p (19201080 / 10801920) = 1.6×
Audio multiplier: disabled = 1×, enabled = 2×

Best Use Cases

Character Animation — Generate videos that preserve character identity from reference photos.
Social Media Content — Create engaging videos featuring consistent characters.
Storytelling — Produce narrative scenes with identity-consistent characters.
Marketing & Ads — Generate promotional videos featuring specific people or characters.
Multi-shot Production — Create videos with varied camera angles and compositions.

Pro Tips

Use multiple reference images from different angles for better identity preservation.
Use "multi" shot type for more dynamic, cinematic compositions.
Disable enable_audio for faster processing when audio is not needed.
Add negative prompts to avoid common issues (e.g., "blurry, distorted").
Enable prompt expansion for automatic prompt optimization.
Use 720p for drafts and testing, 1080p for final production.

Notes

Both reference_urls and prompt are required fields.
Maximum 5 reference images per generation.
Duration options are 5 or 10 seconds only.
Ensure uploaded image and audio URLs are publicly accessible.
Seed value -1 generates a random seed each time.
If your result don't have sound, please add prompt like "Add background sound".

Wan 2.6 Reference To Video Flash API — Frequently asked questions

What is the Wan 2.6 Reference To Video Flash API?

Wan 2.6 Reference To Video Flash is a Alibaba model for video generation from images, exposed as a REST API on WaveSpeedAI. WAN 2.6 Reference-to-Video Flash turns character, prop, or scene references from images or videos into new video shots with preserved identity, style, and layout plus smooth, coherent motion. Flash version with faster generation speed. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Wan 2.6 Reference To Video Flash API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/alibaba/alibaba-wan-2.6-reference-to-video-flash.

How much does Wan 2.6 Reference To Video Flash cost per run?

Wan 2.6 Reference To Video Flash starts at $0.13 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Wan 2.6 Reference To Video Flash accept?

Key inputs: `prompt`, `audio`, `duration`, `size`, `seed`, `negative_prompt`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/alibaba/alibaba-wan-2.6-reference-to-video-flash.

How do I get started with the Wan 2.6 Reference To Video Flash API?

Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.

Can I use Wan 2.6 Reference To Video Flash outputs commercially?
