# Genesis Usage and Billing

## Billing

Genesis is priced by model. Token-based APIs separate input, output, cache creation, and cache hits, and all are charged as Genesis Credit. See the model details on the console **Models** page for unit prices. For billing definitions and boundaries with other billable items, see [Credit and Billable Items](credit-and-pricing.md).

**The usage page counts only external calls you make with an API key.** Agent, workflow, and similar usage inside AI Studio is recorded under the **AI services** ledger and is not mixed into Genesis console usage.

## View usage

In the Genesis console sidebar, open **Usage**. This page counts only external calls made with an API key.

### What the usage page shows

| Capability | Description |
| --- | --- |
| Time range | Today / this week / this month / custom, and similar |
| Summary cards | Tokens (optionally split into input / cache / output), cost, request count and success rate, average latency, and similar |
| Trends and share | Token trends, model cost share |
| Details | Grouped by model / by key; export if the UI provides it |

Analysis habits:

- **By model**: Compare unit cost and whether cache hit rates are high enough
- **By key**: Attribute cost to applications; dig into logs when something looks abnormal

Non-token usage (such as pages or images, if any) is counted separately or shown side by side on the usage page; follow the console.
