ChatGPT appeared to be disrupted Thursday morning, as thousands of users reported problems with the site.
The website Down Detector showed more than 4,000 reports of problems with the site, starting shortly after 6 a.m.
Users trying to access the site instead saw an error message.
OpenAI, the company behind ChatGPT, did not immediately return a request for comment. Its social media sites did not report any problems as of early Thursday morning.
On Tuesday, President Trump announced a joint venture between OpenAI, SoftBank and Oracle to create at least $100 billion in computing infrastructure to power artificial intelligence. OpenAI’s chief executive, Sam Altman, was at the White House for the announcement.
