“Worldwide desktop and mobile web traffic to the ChatGPT website, chat.openai.com, dropped 9.7% from May to June, according to preliminary estimates.”
ChatGPT traffic fell 9.7% worldwide and 10.3% in the US from May to June, and unique visitors fell 5.7%. Running the mostly free site costs an estimated $700,000 a day. Paying subscribers get GPT-4, which Bing hands out for free. The only number going up is the developer site, up 3.1%, because the money is in selling the model to other companies.
