Result URL expires after 24 hours; save generated video promptlySource for Output link expiry (opens in a new tab)

Audio input limits

Public WAV/MP3 URL, 3–30 seconds, at most 15 MB. Audio longer than the output is trimmed; shorter audio leaves a silent tail.Source for Audio input limits (opens in a new tab)

Prompt rewriting

On by default; optional. Wan 2.6 shot_type only takes effect when prompt_extend is true.Source for Prompt rewriting (opens in a new tab)

Generation controls

shot_type single/default or multi; requires prompt_extend=true and overrides shot instructions in the promptSource for Generation controls (opens in a new tab)

Published availability regions

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

Why it is included

Classification inference: this native Wan 2.5/2.6 API release is separately documented and has no exact checkpoint in the reviewed official Wan-AI public-weight inventory. Public Wan 2.1/2.2 checkpoints are excluded. API availability and inventory absence do not prove private checkpoint lineage; undisclosed parameter counts and architecture are not borrowed from public models.
