What a run costs
A demo verification loop: 50¢. A small frozen-cohort analysis: a few dollars.
You prepay dollars into credits and runs draw them down. One credit is one US dollar.

The meter: 50¢ per CPU-minute, rounded up — 61 seconds bills as two minutes, 3 seconds as one. Every run shows an estimate before dispatch, and no run can bill past what your balance affords.
Every new account starts with $20 of credit — the demo verification loop, 40 times over. Real studies land in the tens of dollars: the grant proves the loop, the packs fund the study.
Card payments are processed securely by Stripe.

-
By Stripe. The Blind Machine never sees or stores your card details.
-
