Seedance 2.0 Fast
The fast, affordable version of ByteDance's #1 video model
Seedance 2.0 Fast is the speed-optimized version of Seedance 2.0 — ByteDance's #1-ranked AI video model. It keeps the core strengths of the full model, including the multimodal @ reference system and native synchronized audio, while generating faster and at a significantly lower cost. On Keyo Studio, Seedance 2.0 Fast is the practical choice for high-volume video work and rapid iteration, where speed and value matter as much as quality.
What is Seedance 2.0 Fast?
Seedance 2.0 Fast is the efficiency-focused variant of ByteDance's Seedance 2.0 model, built for creators producing video at scale. It's based on the same unified multimodal audio-video architecture as the full model — accepting text, images, audio, and video as inputs — but is tuned for faster generation and a lower price per second. It's the sensible default when you need many clips quickly, iterate on concepts, or run a high-frequency content pipeline, rather than rendering a single hero clip at maximum resolution.
Same @ reference system, faster
Seedance 2.0 Fast retains the model's defining feature: the multimodal @ reference system. You can still upload reference images, video clips, and audio, then @-mention them in your prompt to borrow motion, camera language, character appearance, or a visual style — directing the output with real assets instead of words alone. You get that directorial control at Fast speed, which is ideal for testing multiple reference-driven variations before committing to a final render.
Native audio, built in
Like the full model, Seedance 2.0 Fast generates synchronized audio alongside the video in a single pass — sound effects, ambient audio, and multi-language lip-sync — with no separate audio step. This makes it one of the few fast, affordable video models that ships with native sound, so your high-volume output is ready to use without post-production audio work.
Built for speed and volume
Seedance 2.0 Fast generates noticeably faster than the full model, which matters when you're producing dozens of clips, running A/B tests on video concepts, or feeding an automated content pipeline. Its lower cost per second lets you iterate freely — draft your concept, refine your references and prompt, and reserve the full Seedance 2.0 for the clips that truly need maximum fidelity.
Best use cases
Seedance 2.0 Fast is the right choice for high-volume, fast-turnaround video: social media content and short-form clips, ads and product videos at scale, rapid prototyping and reference testing, automated content pipelines, and any workflow where you need many videos at a low cost per generation. When you want Seedance-quality multimodal control and native audio at scale, Fast delivers.
Pricing on Keyo Studio
On Keyo Studio, Seedance 2.0 Fast is priced per second of generated video by resolution: 3 credits per second at 480p and 6 credits per second at 720p. Draft at 480p to lock in motion and composition affordably, then render at 720p for the final result. For maximum fidelity, including 1080p output, the full Seedance 2.0 is available.
Frequently asked questions
What is Seedance 2.0 Fast?
Seedance 2.0 Fast is the lighter, more economical tier of ByteDance's Seedance 2.0, built for faster and more affordable video generation while keeping the reference-driven approach of the full model.
How much does Seedance 2.0 Fast cost on Keyo Studio?
Seedance 2.0 Fast is priced per second of generated video: 3 credits per second at 480p and 6 credits per second at 720p. Draft at 480p to lock in motion and composition affordably, then render at 720p for the final result.
What's the difference between Seedance 2.0 Fast and the full Seedance 2.0?
Seedance 2.0 Fast is optimized for speed and low cost, topping out at 720p, while the full Seedance 2.0 adds maximum fidelity including 1080p output. Use Fast for drafts and volume; use the full model for final high-resolution renders.
What resolutions does Seedance 2.0 Fast support?
Seedance 2.0 Fast supports 480p and 720p output, priced at 3 and 6 credits per second respectively. For 1080p, the full Seedance 2.0 is available.
When should I use Seedance 2.0 Fast?
Use Seedance 2.0 Fast for affordable drafting and high-volume work — generate at 480p to lock in motion and composition cheaply, then step up to 720p for the final. For maximum fidelity, use the full Seedance 2.0.
What can I use Seedance 2.0 Fast for?
Seedance 2.0 Fast is ideal for iterative and high-volume video production — testing concepts, drafting scenes, and everyday work where affordability and speed outweigh the need for 1080p output.
