How many generations a channel will run at once
Four channels in this register publish something about running generations in parallel. One sells it: five sessions free, then about USD 2,080 a month for each additional one. One fixes it at twenty per package, one publishes a figure for every membership tier, and one gives a multiple with no base. As of 2026-10-13.
| Channel | What is published | In the vendor's words | Page read |
|---|---|---|---|
| HeyGen | A multiple, no figure | Business is described as having 2x more concurrency than Pro | pricing page |
| Kling AI | 20, fixed | Each standard developer package lists 20 concurrency | developer prices |
| Kling AI | Unlimited, by subscription | A dedicated generation queue and unlimited concurrent generation tasks, as subscriber benefits | membership plans |
| SceneMixer | 3 free, then 5 to 20 by tier | A free account runs three at once. The paid tiers run five, eight, ten, fifteen and twenty, in order. | paid plan guide |
| Vidu | 5 free, then priced | Five concurrent sessions per account are free; each additional one costs 416,000 credits a month, about USD 2,080 | API prices |
Inclusion rule. Channels whose own published page addresses parallel generation. A channel that mentions queues only in an API status field is not given a row, because a status name is not a limit. Order. Alphabetical by channel, then by the page the figure was read from.
1A per-second price says nothing about a week
A rate per second prices one generation. A season is hundreds of them, and how long that takes is decided by how many can be in flight at once. Two channels at the same rate per second are not the same purchase if one runs twenty in parallel and the other runs one.
This is the same gap the clip-limit column opens from the other side. A rate tells a buyer what a second costs; it does not tell them how long the whole thing takes, and neither number can be derived from the other.
2One channel prices it, which makes the cost visible
Concurrency is usually a quiet property of a tier. On one channel here it is an item with a price on it, and that price is large relative to the generation rates on the same page: an additional parallel session costs more per month than a great deal of footage. Publishing it that way is more informative than burying it, and it also shows what the quiet version is worth on the channels that do not name a figure.
3A multiple is not a quantity
One row here describes a tier as carrying twice the concurrency of the tier below it, and gives no figure for either. That prices the difference without disclosing the amount: two jobs becoming four is a different purchase from twenty becoming forty, and a production planning a delivery week needs the quantity rather than the ratio.
It is recorded as published all the same, in the shape it was published in. A ratio is more than the silence on most of this register, and writing a number into the cell to make the column tidy would be inventing the part the vendor withheld.
