    Limits
    Local messages and cloud chats share the plan's usage allowance. OpenAI gives estimated local-message ranges per five-hour window that vary by model, and says these are estimates, not fixed message limits. Weekly limits may also apply. The usage dashboard shows current values, and the Codex CLI /status command shows them during a session. Estimated message ranges per five-hour window with no published token or dollar conversion for included usage.
