Short answer: The name depends on the provider. BytePlus lists seedance-1.0-pro-fast; Replicate provides an API route named bytedance/seedance-1-pro-fast; Wiro’s comparison calls its model “Seedance V1 Pro Fast.” The available sources do not establish that these labels are interchangeable across providers. Replicate documents a production API route and a 2–12-second duration range. Its listing reports an approximate $0.245 USD for a 1080p, five-second video. Wiro’s five-run comparison found shorter provider elapsed times for Pro Fast than for Seedance 2.0 in each run—but that small test is not a general latency guarantee. (BytePlus ModelArk; Replicate model; Wiro comparison)
What model does “Seedance Pro Fast” refer to?
The selectable name is provider-specific in the sources reviewed: BytePlus ModelArk lists seedance-1.0-pro-fast, Replicate lists bytedance/seedance-1-pro-fast, and Wiro uses “Seedance V1 Pro Fast” in its comparison. These records establish each provider’s label, but do not confirm that the products or versions are equivalent. Use the identifier shown by the provider whose API or interface you plan to use. (BytePlus ModelArk; Replicate model; Wiro comparison)
Do not substitute Seedance 1.0 Pro or Seedance Lite details for Pro Fast. BytePlus’s separate Seedance 1.0 Pro guide describes that model, and its sample API requests use Lite model IDs. (BytePlus Seedance 1.0 Pro guide)
Capabilities and limits depend on the provider
Replicate’s model schema lists a text prompt, an optional image input for image-to-video, a camera_fixed control, and a duration from 2 to 12 seconds (default: 5). It lists fps as an integer with a default of 24, and resolution as a string with a default of 1080p. The schema’s aspect-ratio default is 16:9, and it says that setting is ignored when an image is used. The schema does not enumerate every accepted resolution or FPS value. (Replicate model schema)
Wiro’s article reports different controls in its own interface: text-to-video and image-to-video, 480p, 720p, or 1080p, 5- or 10-second clips, aspect-ratio selection, seed, watermark control, and a fixed-camera switch. Treat these as Wiro-reported controls, not as a universal or API-wide specification. (Wiro comparison)
Can you use it through a production API?
Replicate documents an API route for bytedance/seedance-1-pro-fast. Its Node.js example uses the Replicate client, authenticates with REPLICATE_API_TOKEN, calls replicate.run(), and accesses the returned video URL with output.url(). The following uses the documented input fields with an illustrative prompt. (Replicate examples)
import Replicate from "replicate";
const replicate = new Replicate({
auth: process.env.REPLICATE_API_TOKEN,
});
const output = await replicate.run("bytedance/seedance-1-pro-fast", {
input: {
prompt: "A red paper kite rising above a coastal meadow at sunset",
duration: 5,
resolution: "1080p",
aspect_ratio: "16:9",
fps: 24,
camera_fixed: false,
},
});
console.log(output.url());
The schema lists 1080p as the resolution default. Check the provider’s current schema for accepted settings before relying on other values. This is a Replicate integration, not a BytePlus request example. BytePlus’s ModelArk listing names Pro Fast, but the separate BytePlus article’s Lite examples do not establish a Pro Fast request contract. (Replicate model schema)
How fast is it—and is quality different?
Wiro compared one text-to-video output per model for each of five prompts. Runs used 480p, 9:16, five seconds, with watermark and audio off. Wiro reports these provider elapsed times. (Wiro comparison)
| Prompt | Seedance 2.0 | V1 Pro Fast |
|---|---|---|
| Pottery studio | 90 sec | 25 sec |
| Perfume product | 90 sec | 29 sec |
| Paper craft | 190 sec | 55 sec |
| Hummingbird | 149 sec | 25 sec |
| Neon alley | 112 sec | 56 sec |
These are provider elapsed times, not end-to-end wait times; queueing, uploads, and post-processing may affect the time a user experiences. In those paired outputs, Wiro’s author preferred Pro Fast for paper craft and hummingbird, and Seedance 2.0 for pottery, perfume, and neon alley. With five prompts and one output per prompt, this is a limited comparison—not a general speed or quality guarantee.
Practical choice: consider Pro Fast when rapid iteration is the priority, then compare it with alternatives using your own prompts and settings. For production-critical details such as lettering, inspect the generated clip rather than assuming the model will render them correctly. For broader evaluation considerations, see Token Forge Cloud’s Seedance API evaluation guide.
What does Seedance Pro Fast cost?
Replicate’s listing reports an approximate charge of $0.245 USD for a 1080p, five-second video. Treat that as a Replicate-specific listed price, not a universal Seedance rate. Check Replicate’s current listing for the charge applicable to other settings or configurations. (Replicate model listing)
Wiro says its five completed test records did not retain per-output costs and recommends checking the Wiro run detail for the actual charge; it notes that resolution, duration, and input mode can affect cost. Do not estimate a price from the elapsed-time comparison. (Wiro comparison)
BytePlus’s Seedance 1.0 Pro token prices and CometAPI’s qualitative claim about lower compute cost do not establish a Pro Fast price. Compare the applicable charge in the provider account you intend to use and for the configuration you expect to generate. (BytePlus Seedance 1.0 Pro guide; CometAPI overview)
