Seedance 2.0 Fast
Seedance 2.0 Fast prioritizes generation speed and lower cost while retaining Seedance 2.0's multimodal inputs, synchronized audio, professional camera movements, and in-video text rendering.

Zero Data Retention
AI Gateway does not currently support Zero Data Retention for this model. See the documentation for models that support ZDR.Authentication
AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.
Seedance 2.0 Fast shares inputs and capabilities with Seedance 2.0 but accepts some quality tradeoff for speed. Use it for iteration, volume batch generation, and drafting where turnaround matters more than absolute fidelity.
When to Use Seedance 2.0 Fast
Best For
Iteration and drafting:
Rapid prompt iteration and storyboard exploration where turnaround drives creative velocity
High-volume batch generation:
Content pipelines producing dozens of video variants for A/B testing or personalization
Cost-sensitive production:
Video workflows where per-clip price scales with traffic and the standard tier's cost isn't justified
Multimodal video at scale:
The full input set of Seedance 2.0 at lower cost for high-throughput generation
Preview generation:
Fast first-pass outputs that teams review before committing to Seedance 2.0 for final renders
Consider Alternatives When
Peak output quality:
Seedance 2.0 targets the highest video fidelity when cost and speed aren't the binding constraint
Static image generation:
Use a dedicated image model when motion isn't required
Video understanding only:
Use a vision-language model to analyze existing video rather than generate new content
Conclusion
Seedance 2.0 Fast makes second-generation Seedance video generation practical at higher volumes. For teams iterating on creative content, running personalization pipelines, or drafting before committing to final renders, the Fast variant delivers the same capability set with faster turnaround and lower cost.
FAQ
Both share the same input types, audio capabilities, camera controls, and in-video text rendering. The Fast variant trades some output quality for faster generation and lower cost. Choose based on whether peak fidelity or turnaround matters more.
Yes. Audio generation is native and synchronized to the video, with multilingual support for dialogue, sound effects, and ambient audio.
Text-to-video, image-to-video, multimodal reference-to-video (combining image, video, and audio inputs), and video editing and extension. Same as the standard Seedance 2.0 variant.
Yes. In-video text rendering carries over from the standard Seedance 2.0 variant.
Zero Data Retention is not currently available for this model. ZDR on AI Gateway applies to direct gateway requests; BYOK flows aren't covered. See https://vercel.com/docs/ai-gateway/capabilities/zdr for details.
Rates are listed on this page. AI Gateway applies no markup on video generation, so the rate matches the direct ByteDance provider price.
Set the model to bytedance/seedance-2.0-fast and call it through the AI SDK's generateVideo function. AI Gateway handles authentication, retries, and failover across bytedance.
