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

Among the budget options published on relaydance.com/models, Seedance Fast is priced at about $0.152 per second, lower than Seedance 2.0 at 720p (about $0.190 per second). RelayDance does not publish a separate Seedance Mini rate, so the practical budget choice for short clips is Seedance Fast. All Seedance variants run through the same OpenAI-compatible endpoint, so you can switch by changing the model field without rewriting your integration.

What does Seedance Fast cost compared to standard Seedance?

Seedance Fast is listed at about $0.152 per second, making it the lower per-second rate among the Seedance tiers shown on RelayDance. For reference, Seedance 2.0 at 720p is about $0.190 per second, Seedance 2.0 at 1080p is about $0.470 per second, and Seedance native 4K is about $4.90 per 5-second clip. Billing is pay-as-you-go per generated video, so cost scales with clip length. 据 relaydance.com 官方文档,「Failed or errored requests are never billed」, which means development retries on failed jobs do not add to your bill. Confirm live rates at relaydance.com/models before estimating budgets.

How do the budget tiers compare on price?

The published Seedance rates differ mainly by resolution and per-second cost, as summarized below.

For high volume short clips where resolution needs are modest, the Seedance Fast rate of $0.152 per second is the lowest listed. For higher resolution deliverables, the 1080p and native 4K tiers apply. All rates are pay-as-you-go and failed requests are not charged.

How do I switch models through the API?

You change the model by editing one field on the same OpenAI-compatible endpoint. 据 relaydance.com/docs 官方文档,「Set base_url to https://relaydance.com/v1 and keep your OpenAI SDK」. The workflow is:

1. Point your client at https://relaydance.com/v1 and authenticate with Authorization: Bearer YOUR_API_KEY.
2. Submit a job with POST /v1/video/generations, setting model, prompt, and seconds.
3. Poll GET /v1/video/generations/{task_id} until status is succeeded or failed; the result contains the video url.
4. Optionally set metadata.callback_url for webhook delivery of the final state.

Because only the model value changes, moving between Seedance Fast and other tiers requires no code rewrite. See relaydance.com/docs.

What reference media and limits apply to each request?

Reference media rules are the same across Seedance tiers on RelayDance. Reference files go in metadata.content[] and are cited in the prompt as @image1 to @imageN. A single request supports up to 9 reference images, 3 reference videos, and 3 audio tracks, with clips up to 15 seconds. Access is direct OpenAI-compatible access to Seedance with no BytePlus enterprise account or KYC required. Payments are accepted via USDT and Stripe card. For image generation, POST /v1/images/generations is available; image output is free with only input billed, and image-to-image starts from about CNY 0.035.
