TREE NEWS update: Kuaishou’s Kling AI said on Sept. 28 that Kling 4.0 will officially launch in October, with Kling 4.0 Flash opening for limited early access the same day. The model supports 4K and 1080p 10-bit HDR output, accepts up to 10 images, 5 videos and 7 subjects in a single task, and can generate videos up to 30 seconds long with long takes and continuous narrative.
Kuaishou’s Kling 4.0 AI Video Model to Launch in October
The differentiator here is not raw resolution but input density: accepting multiple images, clips and named subjects in one task points to multi-shot consistency, the bottleneck that has kept AI video out of professional pipelines. That matters most for advertising, short-form and previsualization workflows where character and scene continuity across takes is the real cost driver. Whether limited early access translates into predictable, repeatable output at that complexity is the open question.
