Kling v2 vs Sora 2 — Which AI Video Model Should You Use?
Kling v2 wins on realistic human motion — gait, dance, and fine motor movement look the most natural of any widely-available video model. Sora 2 wins on physics, long-range coherence, and multi-character interactions. Kling costs roughly 1/4 as much per clip, making it the iteration-friendly choice; Sora 2 is the quality ceiling for production deliverables.
