If you had trouble accessing AI platforms Thursday morning, you're not alone. Apps and services, including ChatGPT, Claude, and Grok, were down, or experienced issues with service. ChatGPT and Grok were both unresponsive when I tried to use them, while Claude appeared to respond, at least for me.
ChatGPT appears to be experiencing the most issues, at least per Downdetector. The site, which accepts user reports of issues with apps and services, currently shows tens of thousands of reports for ChatGPT alone. Claude and Grok had fewer reports, but still many (thousands) over the course of this morning.
According to OpenAI's status page, the company had experienced issues with both ChatGPT and Codex. Anthropic had also acknowledged issues with Claude, including for its Mythos 5.1, Fable 5.1, and Opus 5 models, and said it is working on a fix. SpaceXAI shows that all Grok functions appear to be down at this time. As of 1:19 p.m. ET, all three services now report that they're now up and running.
It's not clear exactly what caused these issues, or if they were all related to one another. Typically, outages like these are solved relatively quickly, so it's not a surprise that all three were able to get their systems back by early afternoon. I'll continue to monitor the situation and update this piece accordingly.
