As of late 2025, Google’s Gemini AI has experienced a significant surge in popularity, reaching an impressive average of over 750 million users each month.
This marks an increase of 100 million users since its last reported figure of 650 million in November. Following that announcement, Google launched its latest Gemini 3 model, which played a crucial role in driving user engagement.
In contrast, Gemini’s primary competitor, OpenAI’s ChatGPT, reports its active user metrics on a weekly basis, complicating direct comparisons.
In September of the previous year, OpenAI stated—and reaffirmed in January—that ChatGPT has more than 700 million weekly active users. However, it remains uncertain how many users interact with the Gemini platform each week, or how frequently ChatGPT users return to the service.
The conclusion of the year has been particularly strong for Gemini, with Google’s popular Nano Banana Pro image-making tool going viral, effectively doubling its AI user base and establishing itself as a formidable opponent to OpenAI’s offerings.
Looking ahead to 2026, Google has ambitious plans for AI integration. In January, the company announced a partnership with Apple to incorporate Gemini models into Siri, Apple’s virtual assistant. With Apple recently revealing it has over 2.5 billion active devices worldwide, even a modest adoption of Gemini models on those devices could significantly bolster Google’s user statistics.
