Kling 3.0 API pricing: what video actually costs
By the Infer teamUpdated
Kling 3.0 1080p Pro costs $0.10 per second of output on Infer. A 10-second clip runs $1.00, a 30-second spot runs $3.00, and Infer only bills renders that complete: a failed generation costs nothing. That's the number to anchor on. Official Kuaishou pricing and third-party reseller rates both diverge from it, in opposite directions, and neither is confirmed with the same certainty as Infer's own rate card.
Price across providers
| Infer | $0.10/sec, flat | Confirmed — Infer's model page, observed 2026-07-22 |
| Kuaishou official API (reported) | $0.084/sec (standard, no video input) to $0.168/sec (Pro, with video input) | Reported by third-party guides, not pulled from a Kuaishou pricing page directly |
| Third-party resellers (reported) | ~$0.075/sec | Reported by reseller-focused guides, distinct from and not comparable to the official figure above |
Keep those two non-Infer rows separate in your head. The "official" figure and the "reseller" figure are not two quotes for the same thing: one is Kuaishou's own tiered rate card (standard vs. Pro, with or without video input), the other is a markup or discount layer resellers apply on top of API access they've already bought. Neither was confirmed against a primary Kuaishou pricing page in this pass, so both carry a "reported" qualifier rather than being stated as fact.
What a real job costs on Infer
| 5-second test render | 5 sec × $0.10/sec | $0.50 |
| 10-second clip | 10 sec × $0.10/sec | $1.00 |
| 30-second spot | 30 sec × $0.10/sec | $3.00 |
| 100-clip iteration batch, 5-10 sec each | 100 × ($0.50-$1.00) | $50-$100 |
The iteration-batch range is wide on purpose: Kling 3.0 1080p Pro's typical clip length runs 5-10 seconds, and a batch mixing short test renders with longer near-final cuts will land somewhere in that $50-$100 band rather than at either end.
What actually moves the price
Not much, and that's worth saying plainly rather than inventing structure that isn't there. Infer's Kling 3.0 page doesn't list separate rates by resolution: the model captures natively at 4K but ships output at 1080p, and the $0.10/second rate applies either way, as far as the documented pricing block shows. There's no audio line item, because this version of Kling 3.0 Pro doesn't generate native audio. Reference images (up to 5, added to Kling 3.0 in the July 20, 2026 changelog update) don't carry a listed per-reference surcharge either. Volume pricing exists elsewhere in Infer's catalog — FLUX 1.1 [pro]'s own page references a discount at 10,000+ requests/month — but that's a different model's pricing page, and Kling's own page doesn't document an equivalent volume tier. Don't assume a discount schedule that isn't stated for this model specifically.
Billing mechanics worth knowing before you build
Kling 3.0 1080p Pro runs async on Infer: you send a request and get a job ID back immediately rather than waiting on an open connection, then poll or webhook for the finished render. Default rate limit is 60 requests/minute, which matters more for the iteration-batch math above than it looks: at that ceiling, a 100-clip batch takes at least 100 seconds of wall-clock queueing before render time even starts, so budget for that when a client asks how fast $50-$100 worth of test renders will land. None of that changes the $0.10/second rate itself, but it changes what "$1 clip" actually costs you in engineering time if you're firing requests in a tight loop instead of a queue.
Cheaper alternatives if $0.10/sec is too much
Hailuo 02 Pro is Infer's cheapest hosted video model at $0.08/second, 20% below Kling's rate, but its resolution and duration specs aren't confirmed on Infer's own page (the page has returned a server error on every fetch attempt during data compilation, with specs recovered only from meta description text). If silent, 1080p-native quality is the requirement, Kling's $0.10/sec is priced against a real, verified spec sheet. Hailuo's discount comes with more unknowns attached. Run Hailuo 02 Pro on Infer →
Infer hosts more than a dozen video and image models at the same take rate structure. We don't make more or less margin depending on which one you pick, so this isn't a pitch dressed as neutrality.

Frequently asked questions
Does Kling 3.0 bill per second or per clip?
On Infer, Kling 3.0 1080p Pro bills per second of output at a flat $0.10/second, regardless of clip length within its 5-10 second typical range. There's no separate per-clip or per-job fee layered on top: a 5-second clip is $0.50, a 10-second clip is $1.00.
Does 4K output cost more than 1080p?
Infer's Kling 3.0 page doesn't list a resolution-based price tier. The model supports native 4K capture but ships output at 1080p, and the $0.10/second rate doesn't vary by resolution on Infer as of July 22, 2026. If a 4K delivery tier exists, it isn't documented on Infer's pricing block; don't assume a multiplier that isn't stated.
Is there an audio add-on cost for Kling 3.0?
No. Kling 3.0 1080p Pro on Infer has no native audio in this version, so there's no audio line item to price. If you need synchronized sound in the same render, that's a reason to look at Seedance 2.0 Pro or Veo 3.1 Fast instead, both of which generate audio natively.
Is there a free trial for Kling 3.0 on Infer?
Infer's per-second API pricing for Kling 3.0 doesn't carry a documented free-trial credit on its model page. Infer's separate $49/month Unlimited subscription does advertise a 1-day free trial, but that's a flat-rate consumer plan, not the metered API rate this article covers. Check which billing path you're actually using before assuming a trial applies.
