What does $1 buy on Sume? Seconds of video, TTS characters, images

One dollar buys about 15 seconds of Wan 3.0 at 480p once the platform fee is included, roughly 19000 characters of speech, or a few low-tier images. It does not buy the shortest Seedance 2.5 clip, which is $1.074709 before the fee. These are all computed from the repo's rate sources and rounded down to whole units.

The unit prices

Sume's sell price is the provider list price multiplied by 1.25, rounded up to a micro-dollar. A 5.5% platform fee is added to the model amount at reserve time. The "per $1" column divides $1,000,000 micro-dollars by the unit price plus fee and rounds down.

Reading the table

The Seedance row shows 0 because the 4-second 480p minimum already costs $1.133817 with the fee. Wan 3.0 accepts clips from 2 seconds, so the smallest Wan clip at 480p is $0.131875 with the fee. Per-second Wan and Seedance prices only compare fairly at the same duration and resolution, which is why the 10 dollar top-up post uses fixed durations.

If your balance is smaller than the job

A job whose price plus fee exceeds the balance is refused with 402 insufficient_credits at submit; nothing is charged. The fee is why a balance equal to the sticker price is not enough. See the fee post for monthly totals.
