A $4.44 ceiling per clip at 1080p or 4K: which Sume models still run

Under a $4.44 cap per clip, Wan 3.0 at 1080p runs 17 s, MiniMax H3 Max at 1080p runs its 15-second maximum, Seedance 2.0 at 1080p runs 5 s, and Seedance 2.5 at 1080p cannot start because its 4-second minimum costs $5.69. Gemini Omni Flash 1.1 reaches its 10-second maximum at both 1080p and 4K.

This is the high-resolution companion to the 80-cent cap page. Only rows that offer 1080p or 4K are listed; 4K exists on Omni only.

Longest clip per high-resolution row

Method: divide $4.44 by the per-second rate, round down to whole seconds, then limit to the model's maximum duration; a result under the minimum means the row cannot run under the cap. Rates are provider list times 1.25, read 2026-10-09.

What the cap does not cover

The cap prices generation only. If you plan a longer piece out of several clips, the timeline render step is billed separately at $0.10 per output minute, rounded up, with a one-minute minimum. A cap per clip is therefore not a cap per finished video.

Also keep the resolution claim honest: MiniMax H3 Max produces 1080p as a latent refinement from native 768p, per the Sume docs, while Omni lists 1080p and 4K as its own output resolutions. Price does not tell you which pipeline made the pixels.

A worked case with the cap as a rule

Suppose a brief says no single clip may cost more than $4.44 and the delivery format is 1080p. Wan 3.0 is the only row that lets you pick a length anywhere from 2 to 17 s, because its 30-second maximum is far above the cap. H3 Max lets you pick 5 to 15 s and never reaches the cap, so its worst case is $3.00. Seedance 2.0 at 1080p reaches the cap at 5 s ($4.2525) and not at 6 s ($5.103), which would exceed it by $0.663.

Lock the rule in code as a check on rate times seconds before the request is sent. The rate comes from the catalog, the duration from your brief, and the model's supported_durations field tells you whether the result is a legal request. That keeps a cap from turning into a surprise 402 or a surprise bill.

When to pick which

If you need the longest single take under the cap, Wan 3.0 at 1080p gives 17 s against 15 s for H3 Max, and the H3 Max clip is cheaper at its maximum: 15 x $0.20 = $3.00 against 17 x $0.25 = $4.25. If you need native audio, Omni and H3 Max report audio support in the Sume docs; check generate_audio in the models response for each row before you rely on it.
