Kling 3.0 Turbo API Pricing: $0.13 per Second at 720p

TL;DR

• Kling 3.0 Turbo is the fast tier of Kuaishou's Kling 3.0. On HiAPI it's billed per second of video: $0.13 at 720p and $0.16 at 1080p, the same for text-to-video (kling-3.0-turbo/text-to-video) and image-to-video (kling-3.0-turbo/image-to-video). A 5-second 720p clip is $0.65.
• Clips run any whole number of seconds from 3 to 15. Every clip comes with sound, and there's no switch to turn it off. There's no 4K; for that, use standard Kling 3.0 or Omni.
• $10 buys about 76 seconds at 720p, roughly fifteen 5-second clips. Turbo is live on HiAPI: open the model page and generate in the browser. New accounts get 200 free credits.

Turbo vs standard Kling 3.0 vs Omni

	Kling 3.0 Turbo	Kling 3.0 (standard)	Kling 3.0 Omni
720p / s	$0.13 (sound included)	$0.10 ($0.143 with sound)	$0.10 ($0.129 with sound)
1080p / s	$0.16 (sound included)	$0.129 ($0.193 with sound)	$0.129 ($0.1645 with sound)
4K / s	—	$0.479	$0.479
Sound	Always on	Optional, off by default	Optional
Clip length	3–15 s	3–15 s	3–15 s
Inputs	Text, or one first frame	Text, first/last frame	Text, frames, references, video transformation

What this means:

• Turbo isn't the cheapest per second. Silent 720p on standard Kling 3.0 or Omni is $0.10. Turbo's $0.13 buys faster generation, with sound already included.
• If you want sound, Turbo usually costs less. Standard with sound is $0.143 at 720p and $0.193 at 1080p, and Omni with sound is $0.1645 at 1080p, all above Turbo. The one exception is Omni 720p with sound at $0.129, $0.001 a second below Turbo.
• Need silent output, 4K, a last frame or reference images? Turbo's sound can't be switched off, and it doesn't take the other fields. Use standard Kling 3.0 or Omni; see Kling 3.0 API pricing and Kling 3.0 Omni API pricing.

Monthly budget

Clips per month × seconds × rate:

Workload	Seconds / month	720p	1080p
100 clips × 5 s	500	$65	$80
300 clips × 5 s	1,500	$195	$240
100 clips × 15 s	1,500	$195	$240

Ways to spend less

• Probe at 3 seconds, 720p: $0.39 per try. Lock the motion, then re-run at the length the cut needs.
• Set duration on purpose: it defaults to 5, and cost scales linearly up to 15.
• Keep 720p for anything that plays on a phone: 1080p costs 23% more per second.
• Use image-to-video to continue a shot: feed the last frame of one clip as the first frame of the next instead of generating a long take.

FAQ

Is Turbo cheaper than Kling 3.0?

Per second, no: silent 720p standard is $0.10 versus Turbo's $0.13. But Turbo includes sound, and against standard with sound on ($0.143 at 720p, $0.193 at 1080p) it costs less.

Does Turbo generate sound? Can it do 4K?

It generates sound, and you can't turn it off. We ran a 3-second 720p text-to-video clip ($0.39) and it came back with a stereo audio track, like both examples on the model page. There's no sound field: Turbo takes prompt, duration, resolution (720p or 1080p), and aspect_ratio on text-to-video or exactly one image_urls entry on image-to-video. Other fields return HTTP 400. No 4K: only 720p and 1080p.

What durations are allowed?

Any whole number from 3 to 15 seconds.

Am I charged for failed tasks?

No. You pay only for clips that generate successfully.

If 5 or 10 seconds is enough and you want a lower price, see Kling 2.5 Turbo API pricing: $0.06 per second, with audio on text-to-video too.

Code is in the Turbo text-to-video guide and the Turbo image-to-video guide, and ready-made prompts in the text-to-video and image-to-video recipes. Or copy the fjord prompt and generate a 3-second test for $0.39.
