# FAQ

> Common usage, billing, and access questions.

## Are customers charged before a job starts?

Submit returns an estimate, but final debit is based on runtime at settlement.

## Why do I see small debits like `0.02`?

At `$2.99/GPU-hour` and `1 credit = $1`, short jobs can settle in cents.

## Where are artifacts stored?

Production artifacts are stored in managed object storage and downloaded through signed URLs.
