On the morning of October 20th, an anomaly occurred with OpenAI's official API interface, causing applications and plugins using its interface to temporarily become inoperable. This includes some services affected, such as the popular conversational AI ChatGPT, where users could not use these applications and services as usual. In response, OpenAI made a statement on their official website, indicating that they have noticed the issue and are working hard to fix it, hoping to restore the normal operation of these applications and services as soon as possible. Although OpenAI's own interface encountered a failure, the OpenAI services on Microsoft Azure, such as ChatGPT, are temporarily unaffected, and users can still use them normally. OpenAI stated that they will accelerate the repair process so that users of the relevant applications and services can return to normal use as soon as possible.
