WAN3 models and billing

Model families

All families generate video. Actual waiting time depends on service load.

Public model IDs

Use GET /v1/models for your key's current permissions. The suffix determines the resolution tier; changing size alone does not change that tier.

Cost

Read the current rate P for your account/group, and its currency/unit, from video pricing.

• Image: P × output seconds.
• Video: P × (output + unique reference video seconds).
• Images and audio do not add billable seconds.
• Identical reference video URLs are counted once and must declare consistent durations. Avoid duplicates.

Ten output seconds plus a five-second reference costs fifteen seconds. Billing is based on video durations, not time spent waiting or a fixed per-generation fee. Do not infer the whole charge from quota_type alone.

Charges may be reserved during creation. Use task and usage/refund records to check the final result.

Duration limits

Output: 2–30 whole seconds. Up to 5 reference videos, 1–15 whole seconds each, at most 15 reference seconds total. Output plus references must not exceed 30 seconds. Thirty-second output therefore cannot include a reference video.

Declare the actual duration. Do not invent a rounding policy for fractional durations; use suitable whole-second media or confirm the handling first.
