Kling 4.0, Kling 3.0 Pro and Kling 3.0 Standard
Kling is Kuaishou's video model, one of the first to make AI video feel usable and still one of the most searched. Kling 3.0 arrived in February 2026 with native audio, 15-second clips and multi-shot storyboards; on fal it comes in Standard and Pro tiers, plus a 4K tier and a faster Turbo line. Kling 4.0 launched worldwide on 16 October 2026 and reached fal's API on 23 October: clips up to 30 seconds with stereo sound, per-shot prompts and up to 15 references, priced by resolution. All three pages below run the same nine clips.

Which one to pick
Kling 4.0
$0.16 per second at 720p via fal
Clips longer than 15 seconds, on-screen text, or a crowd that has to look real. $0.157 a second at 720p with sound, but it adds cuts to short one-shot prompts.
Kling 3.0 Standard
$0.13 per second, audio on via fal
Default choice. $0.126 a second with audio on fal, and the same 15-second, multi-shot envelope as Pro.
Kling 3.0 Pro
$0.17 per second, audio on via fal
When the extra fidelity is worth a third more per second.

Frequently asked questions
Is Kling AI free?
The Kling app gives every logged-in account 66 credits a day, enough for a short 720p clip, and free outputs carry a watermark that cannot be removed. Paid plans start at $10 a month; the API and hosts charge per second.
How much does Kling 3.0 cost?
On fal, $0.084 a second silent or $0.126 with audio for Standard, and $0.112 or $0.168 for Pro, read on 9 September 2026. In the Kling app, 3.0 costs 6 to 12 credits a second depending on resolution and audio.
Kling 4.0 or Kling 3.0?
Kling 4.0 when you need more than 15 seconds or words on screen: it spelled our title card, which both Kling 3.0 tiers garbled. Kling 3.0 Standard is cheaper at $0.126 a second with audio and kept every one of our five-second clips as a single shot, where 4.0 cut mid-clip on five of nine prompts.
