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.
When a Codex or Claude Code session reports subscription rate limits, the Usage page shows a Plan usage section: your plan (such as Plus or Pro) with a meter per limit window — typically the 5-hour window and the weekly window — including how much is used and when each resets. The reading updates as agents work and reflects the provider's most recent report, so it can be a few minutes old between turns. Other providers don't report plan limits, so they don't appear 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.
