Usage and cost

usage.output_video_seconds is the duration the upstream reported, and cost follows it. This model bills output only; input material is never charged (the vendor's words: input material is not billed for now).

notes: what we did to your request

Present only when something was done. The most common one on this model is the ratio filled in for text-only generation:

set ratio=16:9: this model requires an explicit ratio for text-only generation

No key means it went upstream unchanged.

Artifact URLs

output.videos[].url points at our storage. Links are cleaned up periodically — download anything you need to keep.

output.images is always an empty array but the field is always present — it is kept for existing image clients, so it cannot be used to tell the modality.
