Kling AI's brand-new model, Kling 4.0, has entered internal testing and will be officially launched in October, according to a report from Zhitong Finance APP on September 28.

Kling 4.0 centers its core upgrade direction on "realism, controllability, and professionalism": significantly improved dynamic range and complex camera movements are now more stable and fluid, allowing large-scale scenes to be handled with ease; the all-purpose reference feature has been substantially upgraded, with richer reference dimensions and more stable consistency performance; a single native generation can last up to 30 seconds, with long-take and continuous narrative capabilities further enhanced; it supports up to 10 keyframe inputs; and it supports high-specification output in 4K and 1080p 10-bit HDR formats.

At the same time, targeting high-frequency creation scenarios, Kling AI has also introduced Kling 4.0 Flash, which combines high cost-effectiveness with efficient generation speed and is now the first to be open for experience.
