Release date and availability
Kling 4.0 was announced on September 27, 2026. Kling's official Kling 4.0 page says the full model is coming this October, and that Kling 4.0 Flash is available now in a limited rollout to a group of creators. Kling does not give an exact day for the full launch.
Kling's API price page currently notes that its packages do not support Kling 4.0, so API access and API pricing for the new model have not been announced either.
What's new in Kling 4.0
Length and structure: up to 30 seconds in a single pass, up to 10 keyframes anywhere on the timeline to guide camera moves, shot changes and reveals, and video extension forward or backward across passes up to about 2 minutes in total.
References and control: up to 15 references per task across images, videos and subjects, plus the ability to borrow the pacing and camera moves of a reference clip. Kling says on-screen text renders in 9 languages and stays readable in motion, and that re-editing an expression, angle, background or line of dialogue keeps the rest of the frame intact.
Picture and sound: native 4K or 1080p 10-bit HDR, 21:9 ultrawide, steadier motion in action scenes, tighter lip sync and stereo audio, with dialogue across 9 languages, accents and dialects.
Kling 4.0 vs Kling 4.0 Flash
Flash is the lighter, faster member of the 4.0 family: up to 20 seconds per pass at up to 720p, positioned by Kling for everyday creation and value. The full Kling 4.0 is the one with 30-second passes and 4K 10-bit HDR output.
In practice, Flash suits drafts, social clips and testing prompts; the full model is for finals that need resolution, length or keyframed structure.
What it will cost: what is known today
Kling has not published Kling 4.0 pricing as of October 4, 2026. The best available baseline is Kling 3.0 on Kling's own API: $0.112 per second at 1080p without native audio and $0.168 per second with native audio, so a 10-second 1080p clip with audio lists at $1.68. Consumer plans start with Standard at $5.99 a month (660 credits).
Treat any 4.0 price you see before Kling's own announcement as a guess. We will update this page and our AI video API price table when Kling publishes official numbers.
Should you wait for Kling 4.0?
If you need clips longer than Kling 3.0 produces in one pass, keyframed multi-shot sequences, or 4K HDR delivery, the 4.0 feature list targets exactly those gaps, so it is worth testing Flash now and planning a trial of the full model at launch.
If your work is short social clips at 1080p, Kling 3.0 and other current models already cover it at known prices; there is no need to pause production for a launch with unpublished pricing.
