# Credits and billing

> Calls spend credits. The dashboard shows the balance.

A Compiled Agent Model is much cheaper than a frontier model on the runs we have measured. Calls spend credits. The dashboard shows usage during early access. The API is a private preview.

## What the tests show

These are published test figures, quoted as tests. They are not a rate card.

- The home page shows early repeat runs as 5–10× faster.
- Repeat runs are often 10-100x cheaper on our tests. Savings depend on the workflow.
- The repeat-cost essay measures one invoice reconciliation run at 1.5s and $0.00023 per run versus Opus 5.5 at 24.8s and $0.105 per run, roughly 450x.
- The home page lists support ticket triage at about 0.5s and $0.00009 per repeat, versus about 10s and $0.012 for a frontier agent.
