Wan 3.0 per-clip cost: Sume API vs Runway credits

Wan 3.0 on Sume costs $0.0625, $0.125 and $0.25 per second at 480p, 720p and 1080p. A 10-second 720p clip is $1.25, so 100 are $125.00. Runway's API page lists WAN3 at 5 to 20 credits per second at $0.01 per credit (read 2026-10-07), which is $0.05 to $0.20 per second, so Sume is 25 percent higher at the matching ends of the range.

Where the numbers come from

The Sume Video Router docs list wan-3.0 with a resolution-tiered list of $0.05, $0.10 and $0.20 per second (fal 2026-08-24, as cited in the docs) and a 2 to 30 second duration. Sume bills list x 1.25. Runway's page states a credit price of $0.01 and a range for WAN3 of 5 to 20 credits per second across 480p to 1080p. The page summary I read gave the range, not a per-resolution mapping, so the table compares ranges.

10-second clips and 100-clip batches

Multiply per-second by 10 for a clip and by 1,000 for 100 clips of 10 seconds.

Reading the gap honestly

At the low end Sume is $12.50 more per 100 clips ($62.50 against $50.00); at the high end it is $50.00 more ($250.00 against $200.00). If your whole workload is Wan 3.0 on Runway and you do not need anything else, Runway is cheaper. Sume's case is different: the same API key and balance also reach H3 Max, Gemini Omni Flash and the rest of the Video Router catalog, plus Sume's own avatar and media tools, with one job model.

Also check the clip limits. Wan 3.0 accepts 2 to 30 seconds per the Sume docs; I did not read Runway's limit for WAN3, so I make no claim on it.

How to budget a batch

Pick the resolution first, because it is a 4x spread from 480p to 1080p. Then check your plan: Pro's $40 of included usage covers 32 ten-second 720p clips ($40 / $1.25 = 32), and Startup's $140 covers 112. Anything beyond is funded from the wallet at the published rate.

A length sweep

Wan 3.0 is flexible on length (2 to 30 seconds), so the clip price varies a lot. At 720p on Sume, a 4-second clip is $0.50, a 10-second clip is $1.25, and a 30-second clip is $3.75. For 100 clips that is $50.00, $125.00 and $375.00. At 1080p the same lengths are $1.00, $2.50 and $7.50 per clip.

The rule of thumb is that 1080p costs twice as much as 720p and four times as much as 480p, because the tiers are $0.0625, $0.125 and $0.25 per second. To keep a 100-clip batch at $100, the average clip can be 8 seconds at 720p ($1.00 / $0.125), 16 seconds at 480p or 4 seconds at 1080p.
