Cheapest AI video API per second: Sume models ranked by price
Cheapest per output second on Sume: Grok Imagine Video 1.5 at $0.0125, Gemini Omni 360p at $0.0375, then Wan 3.0 and MiniMax 480p at $0.0625. Ranked table.
The cheapest video per output second on Sume is Grok Imagine Video 1.5 at $0.0125, which only does image-to-video. For text-to-video the cheapest is Gemini Omni Flash 1.1 at 360p ($0.0375 per second), then Wan 3.0, MiniMax H3 and MiniMax H3 Max at 480p, all $0.0625 per second. The ranking below uses each model's lowest resolution tier, with Seedance at 480p in 16:9, as of 2026-10-08.
Every price is the provider list multiplied by 1.25. The cheapest tier is a poor guide to the cost of a final deliverable, so the second table compares the same 720p-class setting.

Reading the Seedance numbers
Seedance has no fixed per-second price. At 720p in 16:9 it uses 1280 x 720 x 24 fps / 1024 = 21,600 tokens per second, so Seedance 2.5 is 21.6 x $0.0214 = $0.46224 list per second, or $0.5778 after the 1.25 margin. Seedance 2.0 Mini is 21.6 x $0.0070 = $0.1512 list, or $0.189 billed. At 480p in 16:9 the frame is 864 x 496, which is 10,044 tokens per second, so the figures in the first table follow the same method with a smaller frame.
Caveats
- Prices are provider list x 1.25 as recorded in the repo and can change; the fal-based lists are marked subject to change in the pricing package.
- Cheapest is not best: a 480p draft is for prompt tests, not final delivery.
- Kling bills audio separately: add $0.07 per second for audio on.
