ChatGPT launched in November 2022. By July 2025, 18 billion messages were being sent each week by 700 million users, representing around 10% of the global adult population.

The first full research paper on its use was published today.

Non work messages now represent over 70% of all ChatGPT messages.

The share of messages related to computer coding is relatively small: only 4.2% of ChatGPT messages are related to computer programming, compared to 33% of work-related Claude conversations.

The share of messages related to companionship or social-emotional issues is fairly small: only 1.9% of ChatGPT messages are on the topic of Relationships and Personal Reflection.

The gender gap in ChatGPT usage has likely narrowed considerably over time, and may have closed completely.
