Pricing
What the models cost, plus 5%.
That is the only fee. No subscription. No charge per AI teammate. No equity. Hosting at the cloud’s own price. Every saving Maestro finds goes to you.
Three lines on the bill
Models.
Each model at its list price, plus 5%. Every task shows its model and its cost in the record.
Sponsored models.
Free. AI labs and cloud providers sponsor models through the Zero Build Foundation. Work on a sponsored model costs you nothing.
FoundationHosting.
At cost. ZB Cloud passes each cloud’s own price through, with nothing added.
Why it costs less
Same task. 100 times the price.
The best model for a task is rarely the priciest one. Maestro routes each task to the cheapest model that does it well, and only a failed check pays the top price.

See the whole buildOne balance
One balance. Every model. Every cloud.
Add to your balance once. Every model and every cloud draws from it. The record shows every task, its model, its cloud and its cost, so the bill is never a surprise.
When do I pay?
As the work is done, from your balance. Nothing is charged before a task runs.
What happens when a check fails?
The task goes once more to a stronger model, and both runs are paid. The higher price applies to that one task, not the whole job.
What is a sponsored model?
A model whose maker or host pays for the work done on it, through the Foundation. Builders in a Foundation program use them free.
