Seedance 2.0 Mini API
Seedance 2.0 Mini 轻量视频生成模型，支持文生、图生和多媒体参考生成。
What is Seedance 2.0 Mini
Seedance 2.0 Mini is the lightweight tier of the Seedance 2.0 family from ByteDance's Seed team; third-party materials describe the family as built around multimodal references, native AV sync, and multi-shot narrative, while Mini is the channel-side lightweight/cost configuration. Roko's catalog describes it simply as a lightweight video generation model and lists no standalone official release date or official specs for Mini. Each run produces a 4–15 second clip (default 5 s) at 480p or 720p (default 720p), in adaptive (default), 16:9, 9:16, 1:1, 4:3, 3:4 or 21:9, with audio generation on by default.
Roko integrates the model through the /v1/videos/tasks async task API over the video-task and openai-video endpoints, via the EvoLink channel (source_url: evolink.ai/zh/seedance-2-0), with three routes: text-to-video maps to seedance-2.0-mini-text-to-video, image-to-video to seedance-2.0-mini-image-to-video, and reference-to-video to seedance-2.0-mini-reference-to-video. Input modalities are text, image, video and audio: the image route accepts 1–2 images, and the reference route takes 0–9 images, 0–3 video clips and 0–3 audio clips.
Pricing follows the Roko production catalog: $0.044/s at 720p and $0.0209/s at 480p on single-pass routes (text, image, and image/audio-only references); routes that include a video or mixed reference bill dual-pass at $0.0275/s (720p) and $0.0132/s (480p), computed as max(input, output) + output. At 720p that is roughly one-fifth of the standard tier ($0.2189/s) — the cheapest per-second rate on Roko.
Model pricing
Pricing follows the current production configuration and the billing dimensions supported by each route.
| Route | Price | Billing rule |
|---|---|---|
| 文生 / 图生 / 图片或音频参考 | 480p $0.0209/sec720p $0.044/sec | 按输出视频秒数 |
| 视频参考 | 480p $0.0132/sec720p $0.0275/sec | 按 max(输入视频秒数, 输出秒数) + 输出秒数 |
Cost examples
Examples use Roko catalog rates: $0.0209/s (480p) and $0.044/s (720p) on single-pass routes; $0.0132/s (480p) and $0.0275/s (720p) on dual-pass video/mixed-reference routes.
5 s × $0.0209/s = $0.1045
The cheapest paid run possible — ideal for bulk prompt screening.
5 s × $0.044/s = $0.22
Default resolution at default duration — the everyday unit of batch generation.
15 s × $0.044/s = $0.66
Max duration at default resolution; a full clip still costs under a dollar.
(5 + 5) s × $0.0275/s = $0.275
A 5 s video reference with 5 s output bills 10 dual-pass seconds: max(input, output) + output.

Key capabilities
Lowest per-second rate on Roko
$0.0209/s at 480p and $0.044/s at 720p make Mini the cheapest per-second video tier in Roko's catalog — roughly one-fifth of the Seedance 2.0 standard tier at 720p ($0.2189/s).
Standard-family envelope at mini prices
The same envelope as the standard tier: 4–15 s durations, up to 9 image + 3 video + 3 audio references, and 7 aspect ratios including adaptive.
480p/720p dual resolution
Default 720p with a 480p volume option; both are metered per output second, so you can trade resolution for quantity as budget dictates.
Cheap enough to iterate
A 5-second 720p clip costs $0.22 and a 480p clip $0.1045; screening dozens of prompts stays affordable, and only the winners move up a tier.
Main parameters
Parameters come from structured model configuration; unsupported or unconfigured fields are omitted.

Limits
- Resolution tops out at 720p — no 1080p/4K: use the Seedance 2.0 standard tier for high-quality delivery.
- Roko has not benchmarked Mini against the standard tier; expect a quality gap and verify on your own content.
- Routes that include a video or mixed reference bill dual-pass — max(input, output) + output seconds — so long input videos raise the bill even if the output is short.
- Audio generation is on by default; every run's cost includes the audio portion.
- A successful submission is not a successful generation: tasks can fail on content moderation or invalid parameters — the terminal state is authoritative, and output links are time-limited, so re-host promptly.
How it works
- Sign up, create a Roko API key, and top up or confirm your available balance.
- Submit an async task to /v1/videos/tasks with model set to seedance-2.0-mini, choose the text-to-video, image-to-video or reference-to-video route, and set duration, resolution and aspect ratio.
- The API returns a task ID plus a cost estimate based on current rates.
- Poll GET /v1/tasks/{task_id}: a successful submission does not guarantee a successful generation — wait for a terminal state.
- On success the fee is settled by billed seconds; download and re-host the video link promptly before it expires.
Use cases
Prompt screening at scale
The low per-second rate makes bulk prompt runs practical: screen broadly at 480p, then regenerate only the winners at 720p or on a higher tier.
Meme-style clips and short loops
Lightweight 4–15 second output with default-on audio suits memes, reaction loops, and animated stickers where volume matters more than polish.
Two-tier production workflow
Draft broadly on Mini, then send only the strongest prompts to Seedance 2.0 standard or Fast for the final render — Mini keeps the exploration stage cheap.
How it compares
Comparisons below draw on the Roko catalog and third-party public materials.
vs seedance-2.0-fast
Same ByteDance Seedance family: Fast sits at roughly 60% of the standard tier's 720p rate, Mini at roughly 20%. Mini wins on batch cost, Fast keeps more per-clip quality headroom — pick by what a single clip is worth to you.
vs seedance-2.0
The standard tier reaches 1080p/4K and targets ceiling quality; Mini caps at 720p and targets volume. Explore on Mini, deliver on the standard tier.
vs midjourney-video
Mini bills per second from $0.0209 (480p), while midjourney-video bills per call from $0.0825 and must start from an image. Mini is cheaper for short clips and the only option for pure text-to-video.
FAQ
Which endpoint and routes serve seedance-2.0-mini on Roko?
Submit async tasks to /v1/videos/tasks via the video-task or openai-video endpoint: text-to-video routes to seedance-2.0-mini-text-to-video, image-to-video to seedance-2.0-mini-image-to-video, and reference-to-video to seedance-2.0-mini-reference-to-video, with model set to seedance-2.0-mini.
How much does seedance-2.0-mini cost?
Single-pass routes bill $0.0209/s at 480p and $0.044/s at 720p; routes with a video or mixed reference bill dual-pass at $0.0132/s (480p) and $0.0275/s (720p), computed as max(input, output) + output.
Which durations, resolutions and ratios are supported?
4–15 s (default 5 s), 480p/720p (default 720p), and adaptive (default) plus 16:9, 9:16, 1:1, 4:3, 3:4, 21:9 — 7 aspect ratios in total.
How many references can I attach?
Up to 2 images on the image route; on the reference route, up to 9 images, 3 video clips and 3 audio clips.
How does Mini differ from Seedance 2.0 Fast and the standard tier?
Mini is the family's lightweight/cost configuration at roughly one-fifth of the standard tier's 720p rate ($0.2189/s); Fast targets speed at roughly 60%, and the standard tier adds 1080p/4K. Mini tops out at 720p.
Why isn't the video available immediately?
Roko uses an async task model: submissions queue for generation and you poll status until a terminal state, then fetch the video link and re-host it.
Is seedance-2.0-mini free?
No. Generation is billed at the applicable per-second rate — estimated at submission and settled on actual usage against your account balance.
Can I use the videos commercially?
You are responsible for verifying rights and compliance of generated content under applicable terms and local regulations; Roko provides the model access channel.
