Gemini has hit 1 billion monthly active users in roughly 2.5 years, making it the fastest Google product ever to reach that milestone and quicker than ChatGPT's journey to the same figure. The count includes users accessing Gemini directly through its app or web interface, plus Gemini Live sessions, but excludes integration usage through Gmail, Drive, and Search.
For context, ChatGPT took about 3.5 years to reach 1 billion monthly active users, while Android needed approximately 6 years. The rapid adoption underscores the intense competition in the AI assistant space and Gemini's strong market position against OpenAI's flagship product.
