Regarding the slow response of ChatGPT and API services on May 27, OpenAI has completed the repair work from late yesterday night to early today, and the relevant services have now returned to normal.

1. Event Review

  • Issue Confirmation: At 22:47 Beijing Time on May 27, the OpenAI official status page confirmed that there was a "high latency" failure in ChatGPT and API services. According to user feedback from multiple regions, this issue started on the same day early in the morning, characterized by significantly longer waiting times for responses after users submitted questions.

  • Repair Progress: After team investigation and emergency repairs, OpenAI officially confirmed on May 28 at 04:06 Beijing Time that the failure had been resolved and services were back to normal access.

2. Remaining Observations

Although the main high latency issue has been resolved, the OpenAI status page indicates that some auxiliary functions are still under optimization and observation:

  • Codex Function: The context compression speed is still slower than expected.

  • Enterprise Edition Function: There are still some abnormal situations when switching workspaces in the Android version of the ChatGPT Enterprise Edition.

OpenAI is continuously following up on the resolution of these details. Users are advised to pay attention to the latest updates on the official website's status page if they encounter any interface operation issues during use.
