# Pricing

Your own provider keys are free. Managed Keys costs the provider's own price plus a 10 percent fee on each top-up.

## Managed Keys

We require you to prepay a balance, which is then used to pay off model costs for the provider chosen. Add \$100 and we charge your card \$110, and \$100 becomes spendable. The smallest top-up is \$10.

[Billing](/billing) covers the balance, refunds, and running out. Per-model rates are on the [pricing page](https://www.flexinference.com/pricing).
