Kling O3 with native 4K output, synchronized audio, image animation, and reference-driven consistency. On the other side, google's most advanced video model with native audio, 4K resolution, and reference image support.
At 300 credits, Kling O3 4K costs 100 credits less than Veo 3.1 (400 credits). The question is whether the extra cost of Veo 3.1 translates into meaningfully better results for your use case.
