All vikisKling 4.0 Price
Kling 4.0 costs $0.157 a second at 720p and $0.235 at 1080p on Runway's API, or $0.1256 and $0.188 with a 20% discount through Nov 30, 2026; Luma's $30 plan works out to $0.237 a second at 1080p. Kling's own site showed no Kling 4.0 price we could read on Nov 12, 2026.
Kling 4.0 costs $0.157 for each second of 720p video and $0.235 for each second of 1080p at list price on Runway's API, and 20% less, $0.1256 and $0.188, through Nov 30, 2026 UTC (read Nov 12, 2026). That is the only place we found it sold for plain dollars. Kling's own membership page returned no prices to us on Nov 12, and on Nov 6 it listed API rates for Kling 3.0 only, so every other figure here is what a reseller's plan works out to. A full 30-second take at 1080p is $7.05 at list and $5.64 this month.
Next: Kling 4.0 beside Seedance, Veo, Wan and Omni on the same price list, what 4.0 added over 3.0, and Kling 3.0's own API rates or the other 30-second model, which ranks on Arena where Kling 4.0 does not.
Where it is cheapest
The per-second dollars are our division: each plan's monthly price over its credits, times the credits a second of Kling 4.0 at 1080p costs there. Monthly billing; yearly billing is 17% to 20% lower on all three.
| Where | Plan | Kling 4.0 at 1080p | Per second | 30 seconds |
|---|---|---|---|---|
| Runway API | Pay as you go, $0.01 a credit | 23.5 credits a second (18.8 through Nov 30) | $0.235 ($0.188) | $7.05 ($5.64) |
| Luma | Plus, $30 for 10,000 credits | 79 credits a second | $0.237 | $7.11 |
| Pika | Creator, $35 for 2,600 credits | 118 credits per 5 seconds | $0.318 | $9.53 |
| Runway app | Pro, $35 for 2,250 credits | 118 credits per 5 seconds (89 until Nov 30) | $0.367 ($0.277) | $11.01 ($8.31) |
| Pika | Starter, $10 for 600 credits | 118 credits per 5 seconds | $0.393 | more than the month's credits |
| Runway app | Standard, $15 for 625 credits | 118 credits per 5 seconds (89 until Nov 30) | $0.566 ($0.427) | more than the month's credits at list |

Luma's Plus plan is the cheapest subscription by a wide margin: its $30 buys 126 seconds of 1080p Kling 4.0, while Runway's $15 Standard buys 26 seconds at list (35 with this month's discount) and Pika's $10 Starter buys 25. Runway sells the same model at two prices, and the app is the expensive one: a Standard credit costs 2.4 cents against one cent on the API. The 30-second column assumes the app lets you make a take that long; none of the three pricing pages states Kling 4.0's maximum length, and Kling gives the 30 seconds Kuaishou announced.
720p, Flash and Kling 3.0
| Model | Runway API, per second | Luma Plus, per second |
|---|---|---|
| Kling 4.0, 720p | $0.157 ($0.1256 through Nov 30) | $0.159 (53 credits) |
| Kling 4.0 Flash, 720p | $0.094 | $0.096 (32 credits) |
| Kling 3.0 with audio | $0.13 standard, $0.17 pro | $0.12 at 720p, $0.147 at 1080p |
| Kling 3.0 at 4K | $0.43 | $0.441 (147 credits) |
Film Crux's Oct 20, 2026 tutorial ends by pointing heavy users to Kling 4.0 Flash, "a faster, better value version of the model". On these two lists Flash is 40% under Kling 4.0 at 720p and is offered at 720p only; Runway's page adds that its November discount does not apply to Flash. Editing an existing clip is billed differently: with an input video, Runway charges Kling 4.0 at 9.4 credits a second at 720p and 14.1 at 1080p at list, and Luma charges Kling 4.0 Omni at 32 and 47 credits for each second of generated plus reference video.
Kling 4.0 at 1080p costs 38% more than Kling 3.0 pro with audio on Runway's API ($0.235 against $0.17), and at the November rate 11% more. Runway's page does not say whether its Kling 4.0 rate includes sound; Luma's marks its rate as with audio.
Is the price worth it?
Nobody outside Kling has measured that yet. Kling 4.0 has no row on Arena's text-to-video board (dated Nov 8, 2026, read Nov 12), where the best Kling entry is still Kling 2.6 Pro in 31st place. On Runway's API the board's leader, Gemini Omni 1.2 Flash, is $0.10 a second at 1080p, less than half of Kling 4.0, and Wan 3.0, eighth, is $0.20. What Kling 4.0 sells for the extra is the single 30-second take and its reference controls, which a vote on short clips does not score.
What we think
We think Runway's list price for Kling 4.0 at 1080p is below 23.5 credits a second on its API on Mar 1, 2027. Runway is already selling it at 18.8 for a month, Luma's cheapest plan matches the list price to within a fraction of a cent, and a board leader at $0.10 gives buyers a reason to leave. A page still showing 23.5 or more on that day proves us wrong.
Confidence: Possible. Check by: Mar 2027.
