Visitors to OpenAI’s chatbot saw an array of strange behaviour – including the site attempting to download an unusual file. Users joked that the outage meant they would have to use their own brains at work. But it also led to an array of problems across other sites and apps, many of which rely on OpenAI for their artificially intelligent features. Some users reported similar problems at other rival chatbots, such as Anthropic’s Claude and X’s Grok. But those appeared to be at least more minor in their scope, and continued to work for many visitors. *More follows* ## Join our commenting forum Join thought-provoking conversations, follow other Independent readers and see their replies [Comments](#comments-area)
