OpenAI says ChatGPT has 100 million weekly users

One hundred million people are using ChatGPT on a weekly basis, OpenAI CEO Sam Altman announced at its first-ever developer conference on Monday. Since releasing its ChatGPT and Whisper models via API in March, the company also now boasts over two million developers, including over 92 percent of Fortune 500 companies.

OpenAI announced the figures as it detailed a range of new features, including a platform for building custom versions of ChatGPT to help with specific tasks and GPT-4 Turbo, a new model that has knowledge of world events up to April 2023 and which can fit the equivalent of over 300 pages of text in a single prompt.

Whichever way you slice the numbers, ChatGPT is still enormously popular and hasn’t even celebrated its first birthday as a public service yet.

This isn’t the first time we’ve seen large user numbers associated with OpenAI’s chatbot. Back in February, Similarweb estimated that the tool had already reached the milestone of attracting 100 million unique visitors in a single month and 25 million visitors a day. But today’s announcement is notable for being an official data point from OpenAI itself rather than a third-party estimate.
