Kling 3 at 1080p: $0.14 a second, 44% below Wan 3.0's $0.25 on Sume

For a silent 1080p clip, kling-3 is $0.14 a second on Sume and wan-3.0 is $0.25, so Kling is 44% cheaper: a 10-second clip is $1.40 against $2.50. Kling charges the same at 720p, which makes 1080p the right setting there. Wan is cheaper at 720p ($0.125) and 480p ($0.0625), so the 1080p price is the only place Kling wins.

Prices are list times 1.25, from the Video Router guide, read 2026-10-05. Add audio and Kling rises to $0.21, which is still below Wan's 1080p rate.

Rates at each resolution

Sume bills the provider list price times 1.25 and rounds the job up to the cent, so a one-second figure here is a rate, not a charge.

Where Wan still wins

Wan takes 2 to 30 seconds, Kling 4 to 15. Wan takes reference images, clips and audio; Kling takes none. Wan's ratios are 16:9, 4:3, 1:1, 3:4 and 9:16; Kling takes 16:9, 9:16 and 1:1.

So the rule is narrow: for a 1080p clip of 4 to 15 seconds with a first frame, optional last frame and no references, Kling is the lower bill. For anything with references or a longer cut, or any draft at 720p or below, use Wan.

• 1080p, 4 to 15 s, 16:9, 9:16 or 1:1, no references: Kling 3.
• 720p or 480p: Wan 3.0.
• Over 15 s or with references: Wan 3.0.
