Wan 3.0 for 500 prompts: 480p, 720p or 1080p costs 1x, 2x or 4x

A 500-prompt library of 8-second Wan 3.0 clips costs $250.00 at 480p, $500.00 at 720p and $1,000.00 at 1080p on Sume. The price doubles with each resolution step, so the resolution you pick matters more than any choice of prompt.

Teams that lose the sora-2 endpoints (OpenAI removed the Videos API on 2026-09-24, with no replacement listed) often re-render their whole stored library once. At 500 prompts, a one-step resolution decision moves the total by hundreds of dollars.

The three tiers

Wan 3.0 is priced per second by resolution, with a list price of $0.05, $0.10 and $0.20. Sume bills the list price times 1.25 and rounds up to the cent for each clip.

The arithmetic, once

At 480p an 8-second clip is 8 x $0.05 = $0.40 list. Multiply by 1.25 and you get $0.50, which is 50 cents. Multiply by 500 clips: $250.00. The 720p and 1080p tiers repeat the step with $0.10 and $0.20 per second, giving 100 and 200 cents.

Because every clip is a whole number of cents already, there is no rounding drift across 500 clips at these lengths. That is not true for every length; see the rounding effect on 3-second Wan clips.

Longer clips scale the same way

Wan 3.0 accepts 2 to 30 seconds, so a library that held long shots can stay on one model. A 12-second 720p clip is 150 cents, a 20-second one is 250 cents, and a 30-second 1080p clip is 750 cents, which is $7.50. The price is linear in seconds at each tier, so a 30-second clip costs the same as three 10-second clips at the same resolution, and you can split or join by whichever editing step is simpler for you.

A 480p pass is a sketch, not a preview of the final

Sume's v1 video models do not accept a seed, so a 480p render is a different generation from the 1080p render of the same prompt. Use the cheap tier to judge whether a prompt is usable, not to approve a specific take.

A reasonable plan for a 500-prompt library is to render all 500 at 480p for $250.00, drop the prompts that fail, and re-render only the survivors at the final resolution. If 150 survive and go to 1080p, the second pass costs $300.00, for a total of $550.00, against $1,000.00 if you had rendered everything at 1080p.

• Set resolution explicitly on every request; do not rely on a default.
• Wan 3.0 accepts 2 to 30 seconds, so the length column above can go beyond 12.
• Read the live numbers from GET /v1/videos/models before a large run.
