Request notes

Wan commonly uses input and parameters; frame-guided and reference-media modes must not be mixed.

Request parameters

Input and output limits

I2V media must follow a supported combination such as first_frame, first_frame+last_frame, first_frame+driving_audio, or first_clip with the documented optional end frame. Each media type appears at most once; output is 720P or 1080P.

Supported scope

This page covers Modelflare model generation and editing calls. Search or map enrichment, voice management, and element-library management are resource APIs outside this public model-call surface and are not required request fields.

Pricing and billing

This model uses per-second video billing. See the model pricing page for the current customer price, reference list price, and complete specification.
