Kuaishou Teases Kling 4 as Leaks Point to 120-Second Video and 4K Images
After a quiet period, Kuaishou's Kling team officially teased Kling 4, claiming it will change the competitive landscape of video models. Shortly after, detailed specs attributed to a Dev Mode leak surfaced covering Kling 4.0 Preview, 4.0 Flash and Kling Image 4.0, none of them officially confirmed.
Confirmed
- The Kling team has officially announced that Kling 4 is coming (relayed by lipeng0820), but only as a teaser — no official capabilities, benchmarks or release date yet.
Unconfirmed
- Per @koltregaskes citing a Dev Mode exclusive: single video generations up to 30 seconds, extendable to 60 seconds; a 120-second long-video mode; resolution up to 1080p.
- Kling Image 4.0 with up to 4K image generation.
- An Omni Reference feature supporting up to 15 reference elements (per @xiaohu).
- Multilingual audio-video sync with up to 3 voice references (per @xiaohu and @koltregaskes).
- The existence and positioning of Kling 4.0 Preview and 4.0 Flash.
Why it matters
- If accurate, 30–120 second generation lengths and 15 reference elements would far exceed current mainstream video models, potentially redefining the usability boundary of long-form AI video.
- The official "landscape-changing" claim plus concrete spec leaks make Kling 4 one of the most-watched upcoming releases in video generation, pending official confirmation and hands-on testing.
