The Usage page combines Codex and Claude Code activity from your connected environments. It reads the providers' local session history and shows API-equivalent token cost, processed tokens, cache savings, provider shares, and model breakdowns. Subscription billing is separate from the raw token cost shown here.
Use Past 24h for an hourly chart covering the exact rolling 24-hour period. The 7 days, 30 days, and 90 days ranges use daily resolution. Cost and token toggles update both the headline and chart, and refreshing rescans every connected environment.
