Seedance 2.0 vs Kling 3.0
Two multimodal video models, compared on the specs
Seedance 2.0 (ByteDance) and Kling 3.0 (Kuaishou) both generate up to 15-second clips with native audio and 4K output. They differ most in how much reference material one request can carry, which aspect ratios they render, and how shots are controlled. Kling has since announced Kling 4.0 (2026-09-28); this page compares the 3.0 family that is widely available.
