Usage limits
Codex usage limits explained
Codex meters usage against a 5-hour and a weekly rate-limit pool shared with your ChatGPT plan. JP reads the official percentages automatically.
JP the Cat shows Codex's official used-percent — never a fabricated denominator or a token-based estimate.
The agentic-usage pool
Codex shares an agentic-usage pool on 5-hour and weekly windows. It writes the used-percent and reset time into its rollout logs, so the number JP shows is the one OpenAI enforces — no setup, no login.
Cost is notional
Because Codex is a flat subscription, any dollar figure is notional list price — what the usage would cost at API rates, clearly labelled, never presented as metered spend.
