Head-to-head comparison
Kling 4.0vsWan3.0
Kling 4.0 and Wan3.0 are the two 30-second video models from China's biggest platforms, and both are closed, hosted products. Kling 4.0 leads on control, with up to 10 keyframes and 4K stereo output, but the full model and API are still landing. Wan3.0 is live on Alibaba Cloud with transparent per-second pricing and an unusual document-to-video mode.

Which one should you pick?
Pick Kling 4.0 if
You direct clips with keyframes and references, want 4K with sound, and are already a Kling Ultra subscriber who can use Flash now.
See Kling 4.0 details →Pick Wan3.0 if
You need an API with published per-second prices today, want to turn documents, slides, or web pages into explainer video, or build on Alibaba Cloud.
See Wan3.0 details →Bottom line
Wan3.0 for shipping today with predictable costs. Kling 4.0 for control and quality once the full model and API arrive in October. Both are closed; neither is the open-weight option Wan 2.x was.
