Kling has launched an API for its Kling 4.0 model, with access set to expand gradually to enterprise customers and developers around the world. The rollout means the API launch does not establish that all developers worldwide already have access.

Kling 4.0 can generate a video up to 30 seconds long in a single generation. The model also supports longer shots and continuous narratives.

The model is available on Higgsfield, LibTV, Magnific (Freepik), OpenArt, TapNow, 爱奇艺纳逗Pro, 美图公司, OiiOii, 腾讯设计 Miora and updream.
