Seedance 2.0, Fast, Mini and 2.5: a 10-second 720p price ladder

Sume lists four Seedance ids in the Video Router: seedance-2.5, seedance-2, seedance-2-fast and seedance-2-mini. They share the token formula (width x height x seconds x 24 / 1024) and differ in the rate per 1,000 tokens and in their limits. Choosing the right one for a draft wall saves most of the spend.

Rates and limits

Provider list rates per 1,000 video tokens in Sume's pricing table: $0.0214 for 2.5, $0.0140 for 2.0, $0.0112 for Fast and $0.0070 for Mini. At 720p 16:9, 10 seconds is 216,000 tokens. Sume bills list times 1.25, rounded up.

How to use the ladder

A cheaper draft is a different render, not a preview of the 2.5 final: the API accepts no seed. Judge composition and motion on the draft, not texture.

• Draft concepts on Mini; it costs a third of 2.5 for the same length and resolution.
• Use 2.5 for anything over 15 seconds, or when you need 1080p with the 2.5 look: Fast and Mini stop at 720p, and the other three stop at 15 seconds.
• No default or routing preset selects seedance-2 or seedance-2-mini now, but both stay routable when you name them.
