What To Consider When Choosing a Provider

  • 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.

Pro Fast's speed advantage makes it a practical default for interactive applications. Verify that your provider tier supports the required concurrency before you enable synchronous generation in user-facing flows. Compare rates (N/A; N/A).

When to Use Seedance v1.0 Pro Fast

Best For

  • Near-real-time generation:

    User-facing applications where latency directly affects product quality

  • High-volume production:

    The approximately 72% cost reduction over standard Pro compounds across thousands of daily clips

  • A/B testing and iteration:

    Rapid variation generation enables faster creative decisions without Lite-tier quality compromises

  • Personalized video campaigns:

    Many individualized video assets where speed and cost scale together

Consider Alternatives When

  • Absolute quality ceiling:

    Seedance 1.0 Pro suits workflows with no latency or cost pressure

  • Lite-tier quality suffices:

    Lite T2V offers further cost reduction for text-only prompts

  • Audio-synchronized video:

    Seedance 1.5 Pro adds native voice and sound effects alongside the video

Conclusion

Seedance v1.0 Pro Fast is the practical default for production video workloads that need Pro-tier quality. It narrows the gap between generation speed and visual fidelity, so more real-time and near-real-time apps can stay on Pro-class output. With 3x faster generation and 72% lower cost than standard Pro, choose standard Pro mainly when you have no latency or cost pressure.

FAQ

Approximately 3x faster, with generation costs approximately 72% lower per clip than the standard Pro tier.

Yes. Both T2V and I2V input modalities are supported, with the same resolution and duration options as Pro (480p, 720p, 1080p; two to 12 seconds).

In most cases, no. Pro Fast preserves Pro's facial detail rendering, style consistency, and physical motion accuracy. Edge cases may differ under extreme creative direction.

MP4 files at 24 fps in the selected resolution and aspect ratio.

Yes. The 3x speed advantage over standard Pro makes Pro Fast appropriate for synchronous application flows where standard Pro would require async job queuing.

Rate limits depend on the provider level. Review available providers for documented limits before designing high-concurrency pipelines.
