OpenAI CEO Sam Altman said on Twitter that the problem was caused by “a bug in an open-source library” and that a technical postmortem will be published later as OpenAI sends a warning to ChatGPT users.

ChatGPT‘s chat history function has been unavailable for a few days due to a glitch that leaked short summaries of other users’ discussions on the site earlier this week. A Reddit user first brought attention to the flaw by posting a snapshot of descriptions of ChatGPT discussions that were not theirs, and a Twitter user also provided an image of the same bug.

The event was confirmed by OpenAI, who noted that the glitch only disclosed brief descriptive titles of chats rather than entire transcripts. An FAQ on OpenAI’s website urges ChatGPT users not to reveal any sensitive information in their talks in order to prevent additional data breaches. The business stressed that it is not possible to remove individual prompts from a person’s history, and such chats may be utilized for training purposes.

OpenAI CEO Sam Altman said on Twitter that the problem was caused by “a bug in an open-source library” and that a technical postmortem will be published later. Altman also verified that the library change had been released and certified by OpenAI, but he did not specify when users should expect to access their chat messages.

In reaction to the problem, OpenAI temporarily stopped ChatGPT on Monday, according to Bloomberg. When it was restored later that night, the chat history sidebar was replaced with the statement “History is temporarily unavailable.” The business told consumers that it is “working to restore this feature as soon as possible.”

According to the most recent update on OpenAI’s status page on Monday, service has been restored, but the business is still trying to restore all users’ prior chat histories. Nevertheless, Altman acknowledged that users will not be able to view talks that took place between 4 AM ET and 1 PM ET (1.30 PM – 10 PM IST) on March 27.

“We had a significant issue in ChatGPT due to a bug in an open-source library, for which a fix has now been released and we have just finished validating.

a small percentage of users were able to see the titles of other users’ conversation history.

we feel awful about this.” 

Sam Altman tweeted this after the incident.
