OpenAI’s ChatGPT has crossed 1 billion global monthly active users (MAUs), becoming the ​fastest app ever to reach the milestone, ‌according to estimates from market intelligence firm Sensor Tower, Reuters reported.

The record comes amid growing competition between Anthropic ​and OpenAI for dominance in the rapidly ​expanding artificial intelligence market.

ChatGPT ⁠reached 1 billion MAUs in May, roughly ​three years after launch, surpassing the pace ​set by apps including Google Maps, TikTok, Instagram, and YouTube, Sensor Tower said.
