Last updated: 2026-10-14
The short answer
Kuaishou has committed to a month, not a day: Kling 4.0 launches in October 2026. As of 14 October no launch date has been published.
Timeline so far
| Date | Event |
|---|---|
| 27 Sep 2026 | Kling 4.0 announced on kling.ai with the full spec sheet |
| 28 Sep 2026 | Kling 4.0 Flash early access opens for yearly Ultra subscribers |
| 29 Sep 2026 | fal lists Kling 4.0 and 4.0 Flash as early access; endpoints and pricing "at launch" |
| October 2026 | Full Kling 4.0 launch (Kuaishou's stated window) |
What "launch" will likely mean
- Availability in the Kling app for paid tiers first, then wider plans.
- A developer API on Kling's open platform and on partner gateways such as fal. Expect per-second pricing like Kling 3.0 ($0.084–$0.42/s on fal today, depending on tier, audio and resolution).
- Some headline features (10-bit HDR, two-minute extension) are marked "coming soon", so they may come after the launch.
What this site will do
As soon as a Kling 4.0 endpoint is live, priced and passes our own test render, we switch it on here. Until then Kling 3.0 is the default model (MiniMax H3 and Seedance 2.5 are also available), and every clip is labelled with the model that rendered it.
Try Kling now
You can generate text-to-video and image-to-video clips with Kling 3.0 on this site today; your library labels every clip with the model that rendered it. When Kling 4.0 is published and passes our own test render, we switch it on here — the banner at the top of this page is the live status.
