How long a single generation can run

Two of the sixteen channels publish a maximum clip length next to the rate. SceneMixer caps its Wan 3.0 tiers at half a minute and its MiniMax H3 tiers at half of that; Alibaba Cloud prints the same half-minute ceiling for Wan 3.0. Every other row leaves it unstated. As of 2026-09-22.

Inclusion rule. The limit is taken only from the page that publishes the rate. A limit stated elsewhere in a vendor's documentation is not merged in, because it may describe a different plan or endpoint. Order. Alphabetical by channel name.

1Why this belongs next to the price

Clip length converts a rate into a shot count. A thirty-second beat is one generation where the limit is thirty seconds and two where it is fifteen, and two generations is a cut: the second one starts from nothing, so continuity of pose, lighting and framing has to be re-established by the prompt or accepted as a change. That is an editing consequence, not a billing one, and it does not show up anywhere in a per-second comparison.

It also changes the arithmetic of retakes. Where a beat fits in one generation, a failed take costs that beat. Where it takes two, a failure in either half costs half the beat and leaves a join that has to match footage already approved.

2Why most cells say not stated

Fourteen of the sixteen channels publish a rate without publishing a limit on the same page. The limit usually exists somewhere in the vendor's documentation, often per endpoint or per model version, but pulling it from there and putting it next to a price from a different page risks pairing a limit with a rate that does not apply to it. This site records what the price page states and leaves the rest blank rather than filling it from a different context.

Where a vendor starts publishing the limit alongside the rate, the cell changes and the date on the row moves with it.
