Kling AI drops version 4.0 with stereo audio, multilingual lip sync, and a lighter Flash variant AI video generator Kling AI has released version 4.0 with higher resolution, more precise controls, and a fast Flash variant that the company says should close the gap between AI-generated and professional video.
