Runway Gen-4 Turbo at 5 credits a second: Sume's closest rates

Runway's pricing page lists gen4_turbo at 5 credits a second, or $0.05 at $0.01 per credit. It also lists gen4.5 at 12 credits and act_two at 5. None of these is in the Sume video catalog; the cheapest Sume seconds are Gemini Omni Flash 1.1 at 360p ($0.0375) and Wan 3.0 or MiniMax H3 at 480p ($0.0625).

The cheap end of Sume

These Sume rates are list times 1.25.

What the comparison does not show

The two sets of numbers say what a second costs, not what it looks like. For a fair test, run the same still through both and compare clips, not rates.

When the cheapest second is the wrong one

A 5-credit second only matters if the clip is usable. If a model needs three takes for one keeper, the real rate is three times higher. For draft work, a short 5 or 6 second clip at 480p on Wan 3.0 costs about $0.31 to $0.38 on Sume, and Omni at 360p for 3 seconds is about $0.11.

Runway also lists act_two at 5 credits a second. Sume's catalog has no performance-capture model by that name. Kling Motion Control (kling-motion-1) exists in the Video Router catalog for motion transfer, with a 1 to 30 second range.
