OpenAI Credit and Subscription System Experiences Major Anomaly: Users Suddenly Granted 20x Credit Limit with Intensified API Rate Limiting

According to Vision Beating monitoring, widespread anomalies have been detected in the OpenAI ChatGPT subscription and quota system, causing confusion in usage quotas and model permissions for users at different levels. Some Plus subscription users suddenly saw their interface upgraded to the 20x level, gaining the high quota permissions originally belonging to Pro subscriptions. At the same time, some Pro subscription users paying $200 per month found their account usage quota reset abnormally to 75% or had their quota limit increased fourfold.

The system failure also affected model access permissions. Many Pro subscription users reported that although their account subscription status displayed as Pro, their actual usage performance had been downgraded to the Plus level, and they could not find the GPT-5.5 Pro flagship inference model in the model selection list.

In addition to the display chaos, the Codex quota consumption speed for related developer API accounts has also abnormally accelerated after resets. Some users, after recharging $25, hit the rate limit within just 5 hours. Other community members stated that after recharging $8 in the morning, their quota instantly collided with an hourly message send limit.

As of now, the OpenAI official status page only marks the incident as a possible issue when users are accessing Codex tokens and states that mitigation measures have been implemented. The official statement has not yet publicly acknowledged or explained the quota calculation and account level sync anomaly experienced by ChatGPT subscription users. The community generally believes that backend rate calculation and sync logic failures are the root causes of the rapid depletion of quotas and abnormal rate limits.
