OpenAI Investigates Erratic Codex Usage Limit Resets
On September 10, multiple users reported that their OpenAI/Codex usage quotas dropped abnormally within a short period, across different subscription tiers and use cases, suggesting a serious problem in billing or usage tracking.
Confirmed
- User koltregaskes said their OpenAI usage quota dropped from 30% straight to 0 without warning, questioning why OpenAI tightened usage limits without notification.
- User DimitrisPapail reported that while running routine tasks with Codex and Astra that had been ongoing for weeks, remaining usage fell from 75% to 1% within minutes; a similar anomaly had previously seen it drop from 75% to 1% in one minute, and he believes Codex usage billing has serious problems.
- User AIandDesign, on the MEDIUM tier using Astra (Codex), saw remaining usage fall from 55% to 8% in 30 minutes and tagged the OpenAI lead.
- User gpt2chatbot reported their Codex Pro subscription quota fell from 70% to 17% within two hours, with screenshots as evidence; they noted that even running 5 Astra Max Fast agents over the weekend didn't burn through quota this fast, and called on OpenAI to add usage charts and quota alerts for visibility.
- User jamesbrooksco said they had just received a full Codex usage reset and hadn't used Astra, yet the quota was entirely consumed in under 30 minutes; they directly tagged OpenAI engineer Thibault Sottiaux demanding an explanation.
- User carlosdponx reported that after a morning reset the quota was 100%, but 10 minutes later showed only 36% remaining, with the reset cycle shown as 3 days away; they sought help from Codex team members @thsottiaux and @ajambrosino.
Unconfirmed
- OpenAI has not yet responded, and the root cause of the quota drops (usage tracking bug, billing anomaly, or policy tightening) remains undetermined.
Why it matters
- The incident affects paying and high-tier users (including the 20x plan and Codex Pro), and the reports erupted in a concentrated burst over a very short time, pointing to a systemic anomaly rather than isolated cases.
- Users generally lack usage charts and quota alert tools, making it hard to self-audit where their consumption goes; this product gap was thrown into sharp relief, and gpt2chatbot has publicly called on OpenAI to add visualization features.
