Four Major AI Models Suffer Rare Overlapping Downtime
ChatGPT, Claude, Grok, and Gemini all suffered significant service disruptions within roughly the same few-hour window Thursday morning. OpenAI and Anthropic reported elevated errors and later restored service, while Grok remained impaired and third-party monitoring indicated a likely Gemini outage despite no public acknowledgment from Google.

On Thursday morning, four prominent AI models—ChatGPT, Claude, Grok, and Gemini—experienced a rare overlap of service disruptions. OpenAI and Anthropic reported elevated error rates, which were subsequently resolved, while Grok remained offline, and Google had not yet confirmed a Gemini outage. Major internet infrastructure providers, such as Amazon Web Services, Microsoft Azure, and Cloudflare, did not report extensive problems at the time of reporting.
However, third-party monitoring service DownDetector noted a surge in issue reports for all three platforms this morning.
Despite rare instances of such AI models going down, the simultaneous interruptions of all four were unprecedented. Claude's uptime over the last 90 days stood at 99.4 percent, with a similar three-hour partial outage reported on August 24. Similarly, OpenAI's ChatGPT boasted a 99.63 percent uptime, while ChatGPT Codex achieved 100 percent. On August 31, ChatGPT experienced a period of heightened latency referred to as its "Work Mode."
