OpenAI’s ChatGPT and Codex services, Anthropic’s Claude models, and xAI’s Grok service It started experiencing serious access problems around the same time period on September 3.. Multiple models began crashing on the Claude side, with users reporting 404 errors and response issues on ChatGPT, and xAI confirmed the issue with the Grok models on its status page. The fact that more than one major artificial intelligence platform is experiencing problems at the same time shows that the outage is not limited to a single company.
OpenAI on its status page Rising error rates across ChatGPT and Codex He announced that he was researching. Outage tracking data shows that OpenAI recorded the incident on September 3. Notifications from users include ChatGPT web interface not opening, 404 errors and Codex connections being broken. OpenAI later reported that it had implemented countermeasures against the issue and was monitoring the recovery.
On the Anthropic front, Claude models with similar watches experienced problems. According to information provided by The Verge, the problem initially affected more than one Claude model, but the company later narrowed the scope to Claude Opus 4.8 and Opus 5 narrowed it down to models. Anthropic identified the source of the problem and began working on a solution.
xAI, on the other hand, took the outage directly to its own status page. Company, September 3 at 16.43 Grok announced that it was experiencing problems with its models and recorded the outage affecting the Android application under the title “Models outage”. The company’s statement doesn’t give a detailed technical reason, only confirming that the models are experiencing issues.
The reason for the outage in three artificial intelligence services is not yet clear
The fact that the outages occur in the same time period naturally brings to mind the possibility of a common infrastructure problem. However, at this stage OpenAI, Anthropic or xAI have not confirmed that the events are linked. While The Verge reported that the problems in three services were experienced at the same time. There is no evidence yet of a common cause. underlines. For this reason, user comments that AWS, Cloudflare or another common infrastructure provider caused an outage should not be considered as verified information.
The element that makes the picture a little more complicated is Google Gemini. While some news sources report that Gemini users also reported problems, other sources write that Gemini was not affected by the outage. While preliminary data from Notebookcheck indicates that Gemini continues to work, other user reports and news suggest that Google’s service is also experiencing problems. Therefore, it would not be correct to define the outage as a single global infrastructure failure covering all major artificial intelligence services at this stage.
OpenAI’s official status page also Separate case of high error rate for ChatGPT Work Mode in the early hours of September 3 had recorded. The company said it fixed this previous issue in about six minutes. The ChatGPT and Codex issue later in the day reveals a broader picture, as it coincides in time with the outages in Claude and Grok.
If you look at it from the user’s perspective, you do not need to do things like reinstalling the browser or application right now. All three companies released statements confirming or investigating issues with their services. Although services have started to return for some users, access status may vary depending on the region, model and application used.
