Runway Gen-4 Turbo and Wan3 Prime cost per second in dollars

Runway's pricing page, read on 2026-10-02, lists Gen-4 Turbo at 5 credits per second and Wan3 Prime at 6.8, 14 and 28 credits per second for 480p, 720p and 1080p. At the page's $0.01 per credit that is $0.05 per second for Gen-4 Turbo and $0.068, $0.14 and $0.28 per second for Wan3 Prime.

Per-second rates make a 5-second clip look cheap and a 60-second edit look expensive, so the table below does the multiplication. The last sections explain how to price the same clip on Sume without guessing.

What does a clip cost at these rates?

Credits convert at $0.01 each on Runway's developer portal. The rows below are straight multiplication of the listed per-second credits.

Resolution is the lever on Wan3 Prime. Going from 480p to 1080p is a 4.1 times price jump for the same duration, so draft at 480p and render the keeper at the size you ship.

How do I compare that with Sume?

Do not convert one vendor's list to another's. Read the model list on Sume and compare the same duration and resolution. The video surface lists each model with pricing_skus, and the docs describe the billing rule: the workspace USD balance is reserved on submit at provider list times 1.25, for every model, and usage.cost on the job is the billable amount.

That makes the check mechanical: take a model's per-second figure, request the duration you need, and compare the reserved amount with Runway's table above.

Does Sume carry Gen-4 Turbo or Wan3 Prime?

I could not confirm either on Sume from the docs, and a model that is not in GET /v1/videos/models for your workspace is not available through the API. The list is the authority, and it changes; check it the day you build the budget.

What the docs do state is the rule for models that are listed: reserve at provider list times 1.25, capture on success, release on failure. The estimate for a given clip is therefore knowable before you spend, which is the property that matters when a campaign has a fixed budget.

What does a failed clip cost on Sume?

On Sume, a job that fails is released: usage rows go reserved, then refunded, and only completed jobs move to captured. See Usage for the statuses.

So the number to budget is cost per kept clip, not cost per attempt. If you keep one in three takes, multiply the per-clip price by three. The cost-per-keeper post walks through that arithmetic.

How do I turn this into a budget?

Pick the duration and resolution you ship, multiply, and then multiply by your retake rate. A campaign of 40 clips of 5 seconds on Gen-4 Turbo is $10 if every clip is a keeper and $30 if one in three is.

Wan3 Prime at 720p for the same 40 clips is $28 at one keeper per clip. The figures are only list arithmetic, so add whatever your account plan adds on top, and re-read the page before you commit because credit prices and promotions change.

On Sume the equivalent step is to read pricing_skus for each candidate model and compute the reserved amount for your duration. Because the reserve is deterministic from the request and the catalog version, an idempotent replay prices identically.
