Is Sume really fal list x 1.25? Four fal pages checked

Yes: on the four fal pages checked on 2026-10-05, each Sume rate is the fal list rate times 1.25, rounded up to the next USD micro. Wan 3.0, Kling v3 Pro, MiniMax H3 Max and Ideogram 4.5 all agree. This post shows the arithmetic so you can repeat it on any other model you care about.

What was checked

For each model the table lists the fal rate shown on the page and the Sume rate computed from it. Sume's rate comes from its provider-pricing package and docs, and the docs state that the video endpoints reserve provider list times 1.25 and that the Ideogram list price is the fal figure by quality.

Two caveats from the pages

fal's Wan 3.0 page marks its prices as subject to change, so the fal column is a snapshot. fal's H3 Max page shows a temporary 40 percent promotion through October 15. Sume prices the model at the regular list rate and has never priced the promotion, so the Sume rate and the fal promo rate do not have the 1.25 relationship until the promo ends.

The Kling v3 Pro page also lists a voice-control add-on of $0.196 per second. That add-on is not part of the comparison above because the table covers only the audio off and audio on rates.

How to run the check yourself

Take the per-second or per-image list price from the vendor page, multiply by 1.25, and compare to the rate on Sume's API pricing page. Sume works in integer USD micros, so a result with more digits than that is rounded up. For example 112,000 micros times 1.25 is exactly 140,000, while a list of 13,170 micros times 1.25 is 16,462.5, which rounds up to 16,463.

• Multiply the vendor list rate by 1.25.
• Round up to the next micro (one millionth of a dollar).
• Multiply by seconds or images to estimate the request.

The same check in micros

Sume computes in integer USD micros, so the clean way to verify is to multiply the list micros by 1.25. Every row below comes out as a whole number, which is why no rounding shows up in these four models. The H3 Max rows use the regular list, not the promotion.

The checks line up with the Sume rate on the pricing page in every row. If one of your own checks does not, either the vendor changed its page since the rate was last synced, or the page you are reading is a promotion, and in both cases the live Sume figure is what you are billed.

What the 25 percent buys and what it does not

The extra 25 percent pays for the platform: one key and one balance across video, image, audio and tools, a usage ledger, webhooks and the queue. It does not buy a different model or different output. It also means any promotion on the vendor side is yours only if you buy from the vendor directly.

For a lone model at high volume, buying direct is cheaper by the 25 percent. For a pipeline across several models and tools, the single integration is the reason people pay it. Check the vendor pages themselves before quoting: Wan 3.0, Kling v3 Pro, MiniMax H3 Max and Ideogram 4.5.
