Runway wan3_prime is 40% above wan3; Sume lists one Wan 3.0 row

Runway prices Wan 3 in two tiers: wan3 at 10 credits per second ($0.10) and wan3_prime at 14 ($0.14), a 40 percent premium. Sume lists one Wan 3.0 row, wan-3.0, at $0.125 per second at 720p. A 10-second clip is $1.00 on wan3, $1.40 on wan3_prime and $1.25 on Sume, so Sume sits between the two.

The numbers

Runway's page does not say what separates prime from standard, so I make no claim about quality. Sume's catalog gives wan-3.0 at $0.0625, $0.125 and $0.25 for 480p, 720p and 1080p, with a valid duration of 2 to 30 seconds.

What to take from it

Sume's 720p rate is exactly 1.25 times Runway's wan3 rate, which is consistent with Sume pricing from the same provider list. Because wan3_prime costs more than Sume's row, Sume is cheaper than Runway only if the prime tier is the one you need and Sume's wan-3.0 is an acceptable substitute, which is a quality judgment I cannot make from price pages.

The practical test is to run one prompt set through all three and pick on output. If standard Wan 3 is acceptable, Runway at $1.00 per 10 seconds is the lowest price here.

Drop resolution instead

On Sume you can lower cost without leaving the model: 480p is half the 720p rate, so a 10-second clip is $0.625. At 1080p it doubles to $2.50. For another look at the same two vendors see Runway's Wan 3 and Seedance 2 rates against Sume.

Monthly numbers

At 400 clips of 10 seconds each month, Runway's wan3 costs $400.00, wan3_prime $560.00 and Sume's wan-3.0 at 720p $500.00. If you can accept standard wan3, Runway saves $100.00 a month over Sume; if you need prime, Sume saves $60.00 on these pages, subject to your quality test.

Re-read both pages at purchase time, since credit rates and catalog prices change.

What I could not confirm

Runway's page lists wan3 and wan3_prime at 720p and does not explain the difference between them. The comparison is on price alone. All vendor figures were read on 2026-10-09 and are listed in the sources; Sume figures come from its public catalog and docs the same day.
