Seedance 2.0 Fast - Text to Video

Try Seedance 2.0 Fast - Text to Video in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: bytedance-seedance-2-0-fast-text-to-video ByteDance Seedance 2.0 Fast generates video from a text prompt, optimized for speed and cost. Supports 480p and 720p output, durations from 4-15 seconds, multiple aspect ratios, and optional synchronized audio.

Example request

Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call.

Sync
Async
Async with SSE

This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.See the video generation reference for more details.
