Seedance Fast vs Seedance Mini: which budget video model fits your workload

For budget video generation on RelayDance, Seedance Fast is priced at about $0.152 per second, making it the lower-cost option in the documented Seedance lineup. Seedance Mini is not listed among the current published rates, so a direct price comparison is not available. For workloads that need documented pricing today, Seedance Fast at $0.152 per second and Seedance 2.0 (720p at about $0.190 per second) are the choices with confirmed rates on relaydance.com/models.

What Seedance Fast costs and where it fits

Seedance Fast is billed at about $0.152 per second, the lowest documented per-second Seedance rate on RelayDance. This suits high-volume or draft workloads where you generate many short clips and want predictable per-second cost. Because billing is pay-as-you-go and 据 relaydance.com 官方文档「Failed or errored requests are never billed」, retries during iteration do not add cost when a request errors. Clips can run up to 15 seconds per request, so a single 15-second Seedance Fast generation costs roughly $2.28 (15 x $0.152) at the listed rate. Live rates remain on relaydance.com/models.

How Seedance Fast compares to higher-tier options

Seedance Fast trades resolution tiers for a lower per-second rate, while Seedance 2.0 offers 720p and 1080p pricing and a native 4K clip option.

If output resolution is not critical, Seedance Fast keeps per-second cost lowest. For 1080p delivery, Seedance 2.0 at $0.470 per second applies. Seedance Mini has no published rate to place in this table.

How to submit a job on either model

You submit any Seedance job through the same OpenAI-compatible endpoint, so switching models is a config change, not a rewrite. 据 relaydance.com/docs 官方文档「Set base_url to https://relaydance.com/v1 and keep your OpenAI SDK」.

1. Create an API key at relaydance.com/console and send Authorization: Bearer YOUR_API_KEY.
2. POST to /v1/video/generations with model, prompt, and seconds (clips up to 15 seconds).
3. Add optional metadata: ratio, resolution, generate_audio, and callback_url.
4. Attach reference media in metadata.content[] (up to 9 images, 3 videos, 3 audio tracks) cited as @image1 to @imageN.
5. Poll GET /v1/video/generations/{task_id} until status is succeeded or failed, or use callback_url for webhook delivery.

Payment and access considerations

Access to Seedance models on RelayDance requires no BytePlus enterprise account or KYC, and billing is pay-as-you-go per generated video. Payments are accepted via USDT and Stripe card. Because failed or errored requests are never billed, cost tracks successful generations only, which helps when comparing Seedance Fast draft runs against higher-tier finals. For image work, gpt-image-2 bills only input (image output is free), image-to-image starts from about CNY 0.035, and 4K and 1K image output cost the same. See relaydance.com/docs for endpoint details.
