OpenAI confirmed on May 27 via social media platform X that its ChatGPT and API services experienced high latency. Many users reported in the early hours of May 27 Beijing time that the response speed of ChatGPT had significantly slowed down, requiring longer waiting times after submitting questions.   

To address this issue promptly, OpenAI quickly released relevant information on its status page, stating that the service was experiencing high latency. After several hours of investigation and repair, OpenAI confirmed at 4:06 AM Beijing time today that the problem had been resolved and the service had returned to normal.

Throughout this period, the OpenAI team has been closely monitoring user feedback, striving to resolve issues as quickly as possible to ensure a good user experience. Users are also looking forward to the restoration of the service, especially as the reliance on AI assistants in daily work and study has become increasingly evident.
