What is the Seedance 2.0 Fast API?

The Seedance 2.0 Fast API is the speed-oriented option in the Seedance 2.0 line. The modes and limits match Seedance 2.0: durations from 4 to 15 seconds and up to 9 reference images. Fast has no resolution parameter and is priced at the 720p tier. That makes it easy to prototype with Fast and switch the model id when you want to compare against the standard model.

4 ways to generate, one endpoint

Set mode, send the inputs it needs — that's it.

Text to video

mode: "t2v" · prompt

Just a prompt — the model builds the shot from scratch.

Image to video

mode: "i2v" · image_url

Send an image in image_url and it becomes the opening frame.

First and last frame

mode: "flf" · image_url + last_image_url

Set the first and last frame; the model animates everything in between.

Reference to video

mode: "r2v" · reference_images (≤ 9)

Add up to 9 reference images to lock in characters, products and style.

Frequently asked questions

Common questions about this model.

What is Seedance 2.0 Fast?

Seedance 2.0 Fast is an AI video generation model from ByteDance, available through the MakerNice API with one key and one prepaid balance. Seedance 2.0 tuned for speed — same modes, same 4–15 seconds, fixed 720p. Draft here, finish on 2.0 or 2.5.

How long can Seedance 2.0 Fast videos be?

Between 4 and 15 seconds per request, with 5 seconds as the default. You're billed for the duration you request.

How many reference images does Seedance 2.0 Fast support?

Up to 9 reference images, sent in reference_images in reference to video mode.

How much does Seedance 2.0 Fast cost per second?

Seedance 2.0 Fast is billed per second of the duration you request, and the per-second rate depends on the settings you choose; every combination is listed in the price table on this page. Call POST /v1/generations/quote to get the exact amount before you run it. Failed runs are never charged.

Seedance 2.0 Fast vs Seedance 2.5: which should I use?

Use Seedance 2.0 Fast for quick drafts at the 720p tier with 4–15 second clips. Re-run the prompts you like on Seedance 2.5 when you need up to 30 seconds, a resolution choice from 480p to 4K, or up to 16 reference images. Remove any resolution field when you send a request to Fast.

Is Fast a different model or a setting?

It is a separate model id, seedance-2.0-fast. You pick it in the model field of your request, the same way as any other model.

Do I need to change my request when switching from Seedance 2.0?

Only if it sets resolution. Fast has no resolution parameter, so remove that field; the modes, duration range and reference limit are the same, so otherwise changing the model id is enough.

How do I retrieve the finished video?

Poll GET /v1/generations/{id} until the status is succeeded, then request /v1/generations/{id}/outputs/0 with your key. It responds with a 302 redirect to the file.
