Gemini crosses 1B monthly users, Google's fastest-growing product

Google's AI had a two-front day: CEO Sundar Pichai announced that Gemini has passed 1 billion monthly users — Google's 14th product to reach the mark — while the company's medical AI, AMIE, posted what its researchers call the first expert-level results for real-time video consultations.

Gemini has crossed 1 billion monthly active users, Pichai announced on X — making the assistant Google's fastest-growing product ever and its 14th to pass the billion-user mark. The milestone lands less than three weeks after the Q2 earnings call, where Google disclosed 950 million monthly users, up threefold from a year earlier. The growth is a distribution story as much as a model story: Gemini now sits inside Search's AI Mode (itself past 1 billion users), Android, Workspace, and a wave of agentic features like Gemini Spark and Daily Brief, and Google's share of the AI-assistant market climbed to 27.7 percent in the first half of 2026 while ChatGPT's slipped below 50 percent. The number that puts it in perspective: ChatGPT crossed 1 billion monthly users in June, so Gemini has gone from visibly trailing to roughly even in under a year — a reminder that Google's biggest AI asset is its default placement in the lives of billions of people. The milestone is a bright spot against a messy stretch for Gemini's model pipeline — we unpacked that this afternoon in Brin can't fix Gemini by showing up.

Google's medical AI, AMIE, matched or outperformed 30 primary care physicians in real-time video consultations — the first expert-level result for audio-visual medical AI, according to a new paper and research blog post. In a randomized OSCE study spanning 100 clinical scenarios across five body systems, 15 trained patient actors ran 300 standardized consultations comparing AMIE (Video), its text-only counterpart, and human doctors consulting by video. Clinical evaluators rated the Gemini-based multi-agent system on par or better than the physicians on history-taking, diagnosis, management, and physical observation, and patient actors preferred AMIE's approach to assessing and explaining conditions — though doctors still won on rapport and partnership. Google is candid about the limits (fine anatomical detail, subtle emotional cues, fast movements) and is running real-world studies with Beth Israel Deaconess Medical Center and Included Health before anything reaches patients.

What to watch: whether Gemini's user scale translates into agentic wins — and whether Google can finally ship the long-delayed Gemini 3.5 Pro.

Does a billion-user Gemini change how you think about the AI race — or is distribution only half the battle? Tell us in the comments.
