The Announcement
On September 28, 2026, Kuaishou's @Kling_ai account announced Kling 4.0, the next flagship of the Kling video model family. The spec sheet reads like a generational jump: up to 4K output, 10-bit HDR, 15 multimodal references, 10 keyframes, native 30-second generation, and stereo audio. The release date given was simply "coming this October" — a month, not a date.
What Is Actually Shipping Right Now
As of early October, the full model has not launched: kling.ai carries an "All-New Kling 4.0" banner but no price, date, resolution, or HDR details, and Kling 4.0 appears on no public benchmark board yet (the newest Kling entry is 3.0). The only thing shipping is Kling 4.0 Flash, gated behind an Ultra Yearly subscriber tier. An October 2 article by a Kling creative partner described current access as a closed beta, with the official launch still ahead.
Why 30-Second Native Generation Matters
If the spec sheet holds, native 30-second generation is the number to watch: most AI video models top out at 5 to 10 second clips, forcing creators to stitch scenes together. Thirty seconds of continuous generation with 15 multimodal references and 10 keyframes would let a single prompt carry a full scene — dialogue, camera moves, and character continuity — instead of a fragment. Treat the headline specs as claims until independent tests land: one creator post that disclosed Kling paid for it described launch output at 1080p, which conflicts with the "up to 4K" headline and is not yet resolved.
How to Prepare for the Launch
Start by auditing your current Kling workflow: which shots need stitching today, and which would survive as single 30-second generations? Build a library of clean character and location references now, since 15 multimodal references only help if the assets are consistent. Finally, watch the benchmark boards — Kling's last flagship set the anchor on the new Artificial Analysis scale, and where 4.0 lands there will tell you faster than any announcement whether the spec sheet survived contact with real users.
