# Review usage 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.
