The two price sheets (read 2026-10-04)

Runway's wan3_prime is listed separately at 6.8, 14 and 28 credits per second.

What differs besides price

Sume's Wan 3.0 accepts 2 to 30 seconds, with reference images (up to 10), reference videos (up to 5, 15 seconds in total) and reference audio (up to 5, 15 seconds in total). Sume rejects seed, size and provider.options with a 400. The two platforms use different request shapes.

When the 25 percent is worth it

Sume gives one API key and one balance across Wan, Seedance, Kling, MiniMax and Gemini Omni models, with one job envelope and webhooks. If you only ever call Wan 3.0, compare the totals for your volume; if you move between models, a single integration may matter more than the margin.
