Overview
Unlimited generation by plan
The longest clip that runs unlimited at each resolution on each plan, at the model’s base settings. Anything longer, or any resolution marked Gems, runs on Gems.
Base settings. Editing an existing clip bills its input seconds too, so video edits always resolve through the price rather than the carve-outs above.
What it supports on Mage
Best for
- Final-quality video
- Clips longer than 15 seconds, which only Seedance 2.5 reaches
- Work that needs many reference images: up to 8, and up to 29 on Seedance 2.5
- Audio driven by a reference you supply
An example prompt to start from
Limitations
- Strict Filter: ByteDance checks the prompt and inputs before generating and the clip afterwards. A request it refuses fails with a notice that says why and suggests other models to try, and any Gems it cost are refunded. Mage cannot override the filter.
- Seedance 2.5’s headline settings run on Gems. Unlimited on Max is 4 seconds at 480p; 1080p output and the 20, 25, and 30 second durations always cost Gems.
- A first frame and a last frame are available in Advanced only, and a last frame needs a first frame.
- Seedance 2.0 offers a 4K option that always runs on Gems.
Use via API
Seedance is available through the Mage API as theseedance architecture, with model_id selecting the model. Its fields, tokens, defaults, and price are on its API reference page.
