Three overseas AI models suddenly “collectively shut down”. On the evening of September 3, all leading AI services in the US collectively failed. ChatGPT, Claude, and Grok announced service abnormalities, and Google Gemini and Microsoft Copilot also received numerous reports of outages. This large-scale “downtime” incident continued for about 3 hours and 40 minutes. The fault first broke out centrally at around 9:23 a.m. EST on September 3. Despite the sudden collective failure of large overseas models, the domestic big models are still strong. On the evening of the same day, the big domestic model giant Zhipu posted on social media X: “We are still up.” Translated in one sentence — we're still online.
