Nothing is added to a generation itself. A dollar here is a dollar of AI at what the provider charges us, whether it came out of your allowance or out of a top-up. The percentage applies only when you add funds: Indie 33% · BYOK 20% · Pro 20% · Studio 10%. Buy $100.00 of AI on Pro and your card is charged . It covers buying the AI up front before you spend it, the cost of taking the payment, and putting every provider on one bill instead of several.
The bigger plans charge less of it, but that is not mostly what their higher price buys: of the between Indie and Pro, $60.00 is more included AI. The cheaper rate comes with it and costs nothing up front — and buys nothing at all if you stay inside your allowance.
Take the included AI out of each fee and the software alone is on Indie, on BYOK, on Pro and on Studio. It is the same software on all four. What the larger fees also buy is the lower rate on everything past the allowance, which is why the plan that is cheapest overall depends on how much you generate rather than on which price looks smallest.
Bring your own key and we take nothing from that work at all — which is why that plan comes first in the row above.
The monthly price is for everything that is not the AI: the crew that plans the work, the desk you arrange it on, the timeline, and every project you keep here. Servers, the storage your plan names — 100 GB of it on Indie, 1 TB on Studio — the queue that runs a generation while you’re asleep, and the long work of making a multitude of models behave like one tool you can direct. An AI company sells you a model. We sell you somewhere to use it.
