  • How long can a Seedance 2.5 clip be?

    Up to 30 seconds in a single generation, with multi-turn extension for longer sequences.

  • Is Seedance 2.5 really 4K?

    Yes, generated natively at 4K rather than upscaled from a lower resolution render. It also supports 10-bit colour depth for grading in post.

  • How many reference inputs does Seedance 2.5 accept?

    Up to 50 in one request, spanning images, video, audio clips, 3D white models, and style references. Its predecessor accepted 12.

  • How do I call Seedance 2.5 on AI Gateway?

    Use generateVideo from the AI SDK with bytedance/seedance-2.5. The Chat Completions, Responses, and Messages APIs do not serve video generation.

  • Does Seedance 2.5 generate audio?

    Yes. Audio and video are produced together by one model, inheriting the joint generation architecture introduced with Seedance 2.0.

  • How does Seedance 2.5 compare to Seedance 2.0?

    Longer single shots, native 4K, and a much larger reference budget of 50 inputs against 12. ByteDance also reports roughly 20 percent better prompt adherence.

  • Does Seedance 2.5 support Zero Data Retention?

    Zero Data Retention is not currently available for this model. Zero Data Retention is offered on a per-provider basis. See https://vercel.com/docs/ai-gateway/capabilities/zdr for details.
