It is estimated that ChatGPT, the popular chatbot from OpenAI, reached 100 million monthly active users in January, just two months after its launch, making it the fastest growing consumer app. In history, according to a Reuters report that published a study conducted by UBS on Wednesday.

An average of 13 million visitors used GPT chat per day in January, more than double December levels, the report said, citing data from analytics firm Similar web.

"In 20 years after the Internet space, we cannot recall a faster rise in consumer Internet application," UBS analysts wrote in the note.

It took TikTok about 9 months after its global launch to reach 100 million users, while Instagram needed between one and two years, according to the data.

GBT Chat can create articles, jokes, and even poetry and stories in response to prompts.

OpenAI, a private company backed by Microsoft, made the service available to the public for free in late November.

OpenAI announced today, Thursday, a monthly subscription of $ 20, initially for users in the United States only.

The company said it will provide a more stable and faster service, as well as the opportunity to try new features first.

Analysts believe that the big launch of GBT Chat will give OpenAI a leading edge over other AI companies.
