How to check your Codex usage limit
Codex records its own rate-limit percentages. Here is how to check your quota without guessing.
The official source
Codex writes a `rate_limits` block (with `used_percent` and `resets_at`) into its rollout logs under `~/.codex/sessions`. That is the authoritative number — the same one OpenAI enforces.
Reading it live
JP the Cat reads that block automatically with zero setup and shows Codex's 5-hour and weekly used-percent, tagged `official`, next to a clearly-labelled notional cost. Because Codex is a subscription, any dollar figure is list-price, not metered spend.
Common questions
- Does JP the Cat need my OpenAI login to read Codex usage?
- No. It reads the local rollout logs Codex already writes — no credentials, no network.
- Why is the Codex dollar figure called notional?
- Codex is billed as a flat subscription, so a per-token dollar figure is what the usage would cost at API list prices, not what you actually paid.
