In the past few hours, numerous users worldwide have reported difficulties accessing ChatGPT and Codex, OpenAI's flagship artificial intelligence tools. The official OpenAI status page has confirmed a technical issue, with elevated error rates affecting a subset of users. The incident began approximately four hours ago, prompting the company to deploy a mitigation about two hours ago, and engineers are now monitoring the gradual recovery.
The outage impacted both ChatGPT and Codex, with a spike in reports on DownDetector
According to OpenAI, the disruption particularly affected users relying on ChatGPT for text conversations and Codex for code generation. On DownDetector, reports surged during the initial hours but have since declined after the mitigation was applied. However, on social platforms like X, many users still report ongoing issues, indicating that full restoration has not yet been achieved. OpenAI stated that a fix was implemented approximately two hours ago and is now observing the situation to ensure service stability.
