The number of active ChatGPT users has surpassed 400 million weekly users. “We’re very fortunate to be serving 5 percent of the world every week,” OpenAI COO Brad Lightcap told X about the new audience statistics.
This figure is double the weekly active users the company reported in August 2024 and double the number reported in November 2023.
The latest milestone for the AI assistant comes after a huge scandal surrounding a new competing platform, DeepSeek, earlier this year, which raised questions about whether the current crop of leading AI tools was about to be dethroned.
OpenAI is on the verge of simplifying its ChatGPT offerings so that users don’t have to choose which reasoning model will respond to input, and will soon make its GPT-4.5 and GPT-5 models available in chat and API clients. With GPT-5 available for free to OpenAI users, ChatGPT seems poised to continue to expand its audience in the coming months.
