# Seedance 2.5 Draft Mode Documentation Updated

> The Seedance 2.5 docs now cover generating a 480p draft and referencing its task ID to create a 1080p final video through the existing asynchronous API. The guide includes both requests, inherited parameters, limits, separate charges for each stage, and the draft task ID's seven-day validity.

📖 **The Seedance 2.5 docs now explain the two-stage Draft workflow.**

With `doubao-seedance-2-5-260628`, send `draft: true` to generate a 480p draft, then reference it through `content[].draft_task.id` to create a 1080p final video using the existing asynchronous task API.

**The draft and final video are billed separately, and the draft task ID is valid for seven days.** See the [Draft mode guide](https://docs.apiyi.com/en/api-capabilities/seedance2/video-generation.md#draft-mode) for parameters, complete examples, and limits, or the [overview](https://docs.apiyi.com/en/api-capabilities/seedance2/overview.md) for model selection.
