OpenAI’s ChatGPT, xAI’s Grok, and Anthropic’s Claude all began experiencing issues around the same time on Thursday. At about 11AM ET, ChatGPT started returning error messages for users trying to use the chatbot, with its status page saying there are currently “elevated errors across ChatGPT and Codex.”

In addition to preventing users from having conversations with ChatGPT, the outage is also affecting logins, file uploads, voice mode, search, deep research, image generation, and more. OpenAI says it has “applied a mitigation” and is “monitoring recovery,” though its AI tools are still experiencing “degraded performance.” The outage comes as OpenAI teases the launch of Astra, its new AI model.
Meanwhile, Anthropic’s Claude chatbot, Claude Code, and the Claude API went down around the same time, with technical staff member CJ Avilla saying an “infrastructure issue” caused a partial outage across its services. Anthropic says it resolved the problem at around 12:15PM ET.
Grok similarly began experiencing an outage across Android, iOS, and web at 9:30AM ET. Upon trying to prompt the chatbot on X, it returned a message saying: “This model is overloaded right now. Please try again shortly or pick a different model.” xAI has since fixed the issue.
It’s not clear what has gone wrong, or if the issues are somehow related. The Verge has reached out to OpenAI, xAI, and Anthropic with requests for comments but didn’t immediately hear back.
Update, September 3rd: Updated to note that Claude and Grok outages have been resolved.
