Make your video pipeline Kling-4-ready: keep the model id configurable, abstract duration limits, and benchmark Kling v3 now so you can compare cost and quality on day one.
Kling 3 vs Kling 4 API comparison, every claim labelled: what was reportedly announced on 2026-09-28, what is unconfirmed, and what you can call today.

Not through any host we route to as of the last build of this page. Reporting indicated a wider release in October 2026.
Kling v3.0 (Std, Pro, 4K), Kling O3 and Kling Turbo — all in the catalog now.
It should not be: same endpoint and request fields. Expect a new model id and possibly new parameters for longer clips and keyframes.
