Reports of a ChatGPT outage started around 8.44am BST

Update 11.31am | September 3: OpenAI has confirmed that its ChatGPT service is back up-and-running worldwide. The outage lasted roughly 2hr 13mins in total. The Californian firm hasn't revealed what was behind the issues with the chatty AI tool.

Our original story follows below...


ChatGPT is down, preventing the AI chatbot from generating responses for thousands of disgruntled users.

Parent company OpenAI has admitted that some ChatGPT users will not see responses generated by the AI tool this morning and has promised that it's "investigating the root cause". The outage has already lasted an hour.

DownDetector, an independent website that monitors the performance of online services and apps based on chatter across social media, tracked a dramatic spike in reports in the UK earlier today (September 3). Over 1,000 people nationwide are experiencing problems with the OpenAI-owned service every minute.

Around half the number of reports are also being tracked in the US, according to DownDetector. It's possible the ChatGPT outage is linked to a specific issue in the UK and mainland Europe, or it could be due to the smaller number of people awake in the US at the moment.

OPENAI

For those who don't know, ChatGPT is a conversational Artificial Intelligence (AI) tool that uses natural language processing to generate human-like prose, rewrite existing text, answer questions, and generate tables, graphs, and forms of content.

The “GPT” in its name stands for “Generative Pre-trained Transformer,” which means that it has been trained on a vast amount of text from across the internet to “generate” new responses based on the information it has learned.

ChatGPT can perform a wide range of tasks, including writing essays and code, summarising information, assisting with translations, and holding lifelike conversations with users through text, audio, and image inputs.

It's free to use, but OpenAI reserves some features for its paid plans.
