# Seedance: Seedance 2.5 and 2.0 video models with Strict Filter

> Seedance is ByteDance's video line on Mage, with ByteDance's strict content filter: Seedance 2.0 Mini, 2.0 Fast, 2.0, and 2.5. Which plan runs each one unlimited, at what resolution and duration, and what each supports.

Seedance is ByteDance's video line, with four models from Seedance 2.0 Mini to Seedance 2.5, run on Mage with ByteDance's content filter on (Strict Filter). Every model in the line takes Characters, References, audio references, and Character Voices, and can edit an existing clip. Seedance 2.5 is the most capable and the most expensive to run.

## Overview

| Detail | |
| - | - |
| Type | Video |
| Origin | ByteDance, run with ByteDance's content filter on |
| Models | Seedance 2.0 Mini, Seedance 2.0 Fast, Seedance 2.0, Seedance 2.5 |
| Unlimited from | Pro Plus |

## 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.

| Model | Setting | Basic | Pro | Pro Plus | Max |
| - | - | - | - | - | - |
| Seedance 2.0 Mini | 480p | Gems | Gems | 5s | 8s |
| Seedance 2.0 Mini | 720p | Gems | Gems | Gems | 4s |
| Seedance 2.0 Fast | 480p | Gems | Gems | 4s | 5s |
| Seedance 2.0 | 480p | Gems | Gems | Gems | 5s |
| Seedance 2.5 | 480p | Gems | Gems | Gems | 4s |

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

| Feature | Support |
| - | - |
| Characters and References | Yes |
| Reference images | Up to 8, and 29 on Seedance 2.5 |
| Audio references | Up to 3 |
| Character Voices | Yes |
| First frame | Yes |
| Last frame | Yes, with a first frame |

| Durations | Seedance 2.0 Mini: 4 to 15 seconds; Seedance 2.0 Fast: 4 to 15 seconds; Seedance 2.0: 4 to 15 seconds; Seedance 2.5: 4 to 30 seconds |

## 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

```text theme={null}
@sasha walks along the harbour wall as gulls lift off, camera tracking from the side, late light
```

## 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](https://docs.mage.space/api/overview.md) as the `seedance` architecture, with `model_id` selecting the model. Its fields, tokens, defaults, and price are on [its API reference page](https://docs.mage.space/api/models/seedance.md).
