Kling 3 Pro text-to-video is $0.14/s on fal; four Sume ids cost less

Kling v3 Pro text-to-video is listed at $0.14 per second on fal's pricing page, so a 10-second clip costs $1.40. Sume does not list that model: its only Kling row is Kling 3.0 Motion Control at $0.1575 per output second, which transfers motion from a source video and is a different job. If you want text-to-video and the Kling price is the issue, four Sume ids cost less per second.

Four cheaper Sume rows for 10 seconds

Prices are Sume's catalog rates, which are provider list times 1.25. The last column is how much less each costs than $1.40 for 10 seconds.

What the saving does not buy

The fal page also lists Kling v2.5-turbo Pro at $0.07 per second, which is cheaper than all four Sume rows above, and its H3 Max at $0.05. So price alone does not make Sume the low-cost route; it makes four Sume ids cheaper than the newest Kling price on that page. A Kling clip and a Wan clip will not look alike, so run a test set before you swap.

Check supported limits too: minimax-h3 takes 5 to 15 seconds, wan-3.0 takes 2 to 30, and gemini-omni-flash-1.1 takes 3 to 10 seconds, with native audio always on. If you need the audio off, that last id is not a fit.

If you do need Kling

Kling 3.0 Motion Control on Sume costs $0.1575 for each output second from 1 to 30 seconds, so 10 seconds is $1.575. That is higher than fal's $1.40, but the jobs are not the same: motion control needs a driving video. For the fal snapshot in more depth see the fal pricing snapshot.

Running the swap test

Take five prompts you already run on Kling and render each at 10 seconds on minimax-h3 at 768p. The cost is 5 x $0.75 = $3.75, against 5 x $1.40 = $7.00 on fal's Kling v3 Pro. Compare motion, faces and text legibility. If minimax-h3 fails on your hardest prompts, step up to minimax-h3-max at $1.00 per 10 seconds and repeat.

If neither works, the price table is irrelevant and Kling is the right choice.

What I could not confirm

fal's page lists both Kling v3 and v2.5-turbo under a Pro label. It does not state audio, resolution or duration limits on the rows read, so the cost comparison is per second only. All vendor figures were read on 2026-10-09 and are listed in the sources; Sume figures come from its public catalog and docs the same day.
