Kling 4.0 has picked up another shelf. Luma announced the model inside its creative platform on October 23, in a post titled "Kling 4.0 in Luma: Fast Action and Big Camera Moves", and said it is available to every Luma customer for text-to-video and image-to-video work in four aspect ratios: 16:9, 9:16, 1:1 and 21:9. A LinkedIn post repeated the pitch the next day. Neither post states a credit cost, a plan requirement or a per-generation price of any kind.
The pattern is familiar from Kling's own rollout. The model reached general availability on Kling's web interface, MCP and CLI on October 15, at up to 30 seconds in a single pass, with 10-bit HDR output and the enterprise API still listed as coming soon at that date (our October 15 report). What Luma adds is not a new capability. It is distribution: a seat inside a workspace where subscribers already run Veo 3.1, Seedance 2.5 and MiniMax H3 off the same credit pool. Whether that seat is good value depends entirely on the rate card — and this time, the rate card exists.
The rate card, read closely
Luma's pricing page carries a "Cost Per Video Generation" table, and Kling 4.0 is in it, as read on October 25. Text-to-video and image-to-video cost 53 credits per second at 720p and 79 credits per second at 1080p, with audio included at both. Kling 4.0 Omni charges the same two rates for text- and image-to-video; its video-to-video mode costs more, about 66 credits per second at 720p and about 98 at 1080p.
Against the shelf it sits on, the positioning is aggressive. Veo 3.1, in the same table, costs 280 credits per second with audio, at 720p and 1080p alike. Kling 4.0 therefore runs at 19% of Veo's per-second rate at 720p and 28% at 1080p. One row in that table is easy to misread: Veo 3.1 also lists a 140-credit rate, and it is not a lower-resolution price. It is the silent rate, charged at both resolutions; adding audio doubles it. A comparison that sets Kling's audio-included 53 against Veo's silent 140 is comparing two different products.
Against its own predecessor, 4.0 is the premium tier. Kling 3.0 with audio costs 40 credits per second at 720p and 49 at 1080p in the same table, which puts the new model at about 1.3 times the 3.0 rate at 720p and 1.6 times at 1080p.
These are comparisons of Luma's listed per-second credit rates, not evidence that the models deliver equivalent visual quality, audio quality, duration limits or usable-output rates.
Credits are not dollars, and the exchange rate depends on the plan. Our arithmetic: a 10-second clip at 1080p costs 790 credits. On Plus — $30 a month for 10,000 credits, an effective $0.0030 per credit — that clip is about $2.37. On Ultra — $300 for 150,000 credits, $0.0020 per credit — the identical clip is about $1.58. A Plus credit costs 1.5 times an Ultra credit, so the same generation costs roughly 50% more on the entry plan before a single setting changes. At 720p, the same 10 seconds is 530 credits: about $1.59 on Plus, $1.06 on Ultra. These are effective subscription-credit equivalents, not cash prices charged per generation; unused credits, subscription eligibility and billing terms can change the effective economics.
The announcement carried no price, but Luma's pricing table contained the rates when checked on October 25. The publication date of those rows is not established.
The FAQ has not caught up
Read Luma's help material against its pricing page and the launch looks less tidy. The official FAQ for the current app, read on October 25, lists the available video models as Ray3, Ray3.14, Kling 2.6, Sora 2, Veo3 and Veo3.1. The newest Kling in that document is two generations behind the model in the announcement, and 4.0 does not appear at all. The same FAQ describes individual clips as ranging from 4 to 12 seconds depending on the model, which settles nothing about what the Luma route exposes for 4.0. It also prints the first two plan names the wrong way round — Pro at $30 a month and Plus at $90 — where the pricing page has Plus at $30 and Pro at $90. The prices and credit amounts agree on both pages. Only the names are swapped.
That is uneven documentation, not a failed launch; help pages lag product pages routinely. But the FAQ is the second document a careful buyer reads. The FAQ's model list has not caught up with Luma's announced Kling 4.0 availability and its own pricing table.
The comparison that matters is now runnable on price. Kling sells 4.0 direct, on its own plans and credit structure — our October 15 piece covers that side. Luma sells it by the second, inside a shared pool, priced well under Veo 3.1's audio rate and a clear step above Kling 3.0. What a buyer still has to confirm inside the app is the operational detail no rate card carries: maximum duration, resolution and aspect ratios, mode-specific settings and plan eligibility — and whether the 30-second single-pass length from Kling's own platform survives the move. The price, at least, is no longer the missing piece.
