Cost & Usage

The Cost dashboard () shows the brain's usage and spend analytics.

Admin / Curator only

Cost is visible only to users with the get_usage_summary capability (Curator and Admin). Readers see a gated lock message, and the Cost icon is hidden from their rail.

What it shows

• USD and token stat totals, with period-over-period deltas.
• A range toggle (e.g. 7d / 30d).
• A group-by toggle to break spend down by agent, usage type, or model.
• Charts (rendered with Recharts) visualising the trend.

Use it to understand which agents and models drive cost, and how usage is trending over time.
