Quality
Both models come from top-tier Chinese AI labs and produce excellent results, especially for multicultural content. Seedance 2.0's core differentiator is multimodal reference composition — you can use up to 9 images + 3 videos + 3 audio clips as reference assets in a single request, something Kling does not currently offer.
On maximum resolution, both now reach 4K — Seedance 2.0 supports up to 4K (480p / 720p / 1080p / 4k), and Kling 3.0 outputs native 4K at 60fps.

Bottom Line
- Pick Seedance 2.0 if you need: multimodal reference composition, per-second billing for cost control, Fast low-cost variants, webhook callbacks.
- Pick Kling 3.0 if you need native 60fps 4K rendering and don't need multimodal reference composition.
