Google CEO Sundar Pichai announced on X that the Gemini app has become one of the company's fastest-growing products, recently surpassing 1 billion monthly active users. This makes it the 14th Google product to reach 1 billion users. Gemini's rapid growth keeps it in step with OpenAI's ChatGPT, which reached 1 billion monthly active users in June of this year. The data released specifically refers to the Gemini app and does not include AI users from other channels.
