What a per-second rate does and does not include, and which product you are actually calling.
Two notes about the arithmetic of hosted generative video: what the rate card actually charges for, and which of the two checkpoints behind "the model" you are talking to.
I run an independent third-party interface to one of these models. Not the vendor, not affiliated with the vendor, not reviewed by anyone at the vendor before publishing.
That is a commercial interest in the topic and it belongs in the first paragraph. It is also why the material exists: you learn which line of a price list people misread by watching them misread it.
Rates, resolutions and input caps come from the model's published documentation and carry the date they were read. Prices on hosted models move, so a figure here is a snapshot rather than a quote — the current rates live on one page and that page is the one to trust when the two disagree.
Anything that is an observation rather than a documented figure says so in the sentence it appears in.
No rankings, no vendor comparisons, no affiliate links, no referral codes. The reasoning generalises across models; the specific numbers do not, and where a number belongs to one model the text names it.
