# usage Past Pi sessions contain useful signals about where tokens and cost went, but they are scattered across session files. usage opens a local dashboard that summarizes usage by provider and model over useful time ranges. ## Use Run `/usage` in Pi. Choose Today, This Week, Last Week, or All Time with `Tab` or the arrow keys. Use `↑` and `↓` to select a provider, then `Enter` or `Space` to expand its models. Press `v` for usage insights. Press `q` or `Esc` to close the dashboard. The dashboard reads locally stored Pi session files across projects and does not render outside a UI session. Use it only where aggregating those local session records is appropriate for you.
