AI video discounts end today as per-second prices rise

Several AI video generation promotions end on October 31, 2026, so the same seconds cost more from November 1. The rate changes land across fal, HeyGen and Higgsfield, and every figure below comes from the vendor's own page.

The clearest number is fal's H3 Max Turbo, the fast version of MiniMax's H3 video model served on fal. Its own model page gives a 35 percent discount through October 31: 1.6 cents per second at 480p, 2.6 at 768p and 5.2 at 1080p. The rate does not jump straight back to list. fal lists 30 percent off standard from November 1 to 15, at 1.75, 2.8 and 5.6 cents, and the full standard price only from November 16, at 2.5, 4.0 and 8.0 cents, about a 1.5x lift on the 1080p rate.

What each service charges, before and after:

• MiniMax H3 Max Turbo on fal: 1.6 cents per second at 480p, 2.6 at 768p and 5.2 at 1080p through October 31, then 1.75, 2.8 and 5.6 from November 1 to 15, then a standard 2.5, 4.0 and 8.0 cents.
• Wan 3.0 on the Higgsfield API: 2 cents per second on the promotion, 5 cents at list.
• Wan 3.0 Prime on the Higgsfield API: 2.7 cents on the promotion, 6.8 cents at list.
• HeyGen Video: 1 cent per second at the launch price, 2 cents at full price.

The fal rows are fal's own posted schedule, so its 1080p figure passes through 5.6 cents from November 1. The Higgsfield rows are list prices on its API page, and the HeyGen row pairs the 1 cent launch price with the 2 cents its comparison lists.

Higgsfield keeps 60 percent off Wan 3.0 and Wan 3.0 Prime until October 31, a promotion its changelog dates to October 13. Its API pricing page lists the standard model at 5 cents per second normally and 2 cents on the promotion, and Prime at 6.8 cents normally and 2.7 discounted. The page notes a Max Discount continues after October 31, at 50 percent off Wan 3.0 and 40 percent off Prime, so those rates narrow rather than stop.

HeyGen Video's half-price window closes with the month. HeyGen's model page lists the API at 1 cent per second as a launch price through October, and its model comparison puts the model at 2 cents per second at 480p at full price.

Inside Kling the discount is already gone. The 10 percent in-app credit discount for Pro plans and above ended at midnight Japan time on October 30, the .neurocartel round-up reports, crediting a Japanese daily. Kling 4.0 on the Runway Dev API holds a separate 20 percent discount through November 30, the same round-up reports.

The math only becomes money once you count the seconds. A two-minute clip is 120 seconds, so H3 Max Turbo at 1080p costs 120 x $0.052 = about $6.25 before November 1. Through the November 1 to 15 window it is 120 x $0.056 = about $6.72, and at the standard 8 cent rate from November 16 it is 120 x $0.08 = $9.60. That is clip arithmetic, not a project budget: retakes, sound and editing sit on top.

What keeps running matters beside what ends. Genspark holds 50 percent off credits to November 4, Pika H3 Flex runs 50 percent off for two weeks with 15 free generations a day, fal's FLUX 3 Max stays 75 percent off to November 7, and Vidu Q4 Preview keeps 30 percent off image-to-video and reference-to-video to November 30, per the round-up. synon.co.jp dates the Genspark window, the Pika app launch and the Vidu discount the same way.

The .neurocartel round-up reads the moment worth passing on: it advises against stockpiling credits, since monthly packs often beat the percentage a promotion shaves off and the money leaves the account at once, and models either get cheaper or get replaced. That is the outlet's reading. What costs more from November 1 is the retake, and retakes add up fastest on 1080p finals that cannot drop resolution.

Run your own numbers inside your account before November 1: your plan tier and output resolution move the figure, and someone else's table goes stale within a day.
