OpenAI Resets Codex Limits and Investigates GPT-5.6 Sol Usage
OpenAI recently reset usage limits for ChatGPT Work and Codex paid users and is investigating the issue of GPT-5.6 Sol consuming quotas too quickly. The official clarification states that this is not a reduction in subscription quotas, but rather an experience change brought by system fixes, claiming that the fixed model can last 18% longer.
Confirmed
- OpenAI has reset usage limits for paid users of Codex and ChatGPT Work.
- The official team is investigating reports of GPT-5.6 Sol consuming quotas too quickly, explicitly stating that this is not a subscription quota reduction, but an experience change following a fix.
- OpenAI stated that relevant fixes could improve the token efficiency of GPT-5.6 by about 18%.
- The previously temporarily suspended 5-hour rate limit has been announced to be restored, but it will remain temporarily suspended while the GPT-5.6 Sol issue is being investigated.
Why it matters
- This event directly affects the actual available quotas and workflow continuity for ChatGPT Work and Codex paid users. OpenAI's timely reset of limits and suspension of the 5-hour restriction aims to protect the user experience while investigating abnormal model consumption, preventing users from being unable to use the service due to abnormal usage. Meanwhile, the expected improvement in token efficiency brings a positive signal for developers.
