The race between the world's two best-known AI assistants just crossed a symbolic line. Google says its Gemini app has topped one billion monthly users, its 14th product to reach that mark and, according to chief executive Sundar Pichai, its fastest-growing ever. The climb has been steep, from about 750 million monthly users earlier this year to 950 million in July and a billion in August, an expansion of roughly 250 million in a matter of months.
Two billions, measured differently
Gemini's milestone roughly matches OpenAI's ChatGPT, but the two count in different ways, and that matters. Google is reporting monthly active users for Gemini; OpenAI has leaned on weekly active users for ChatGPT, a milestone it highlighted on 6 August, having reported 900 million weekly users as recently as February. Market data from Sensor Tower, reported by Reuters, put ChatGPT at a billion monthly app users back in May. Either way, the takeaway is the same: chat assistants now operate at a scale once associated mainly with the world's largest internet platforms.
How people use it
Google also shared how the app is being used: about 63% of Gemini users talk to the assistant with the voice feature, and it now generates more than 150 million images a day. More than 100 million people use it on iOS, and the billion-user mark comes soon after a Q2 earnings call at which Google flagged over 950 million monthly users, with daily active users tripling in a year. Google's AI Mode in Search has separately passed a billion monthly users, though this figure counts only the Gemini app, not those other channels. Even so, Pichai called Gemini the company's fastest-growing product ever, a notable claim from a firm with fourteen billion-user products.
Scale isn't free
Reaching that many users is expensive. Alphabet, Google's parent, generated about $39.1 billion in operating cash flow last quarter but spent roughly $44.9 billion on infrastructure, much of it tied to AI and cloud. That left about $5.8 billion in negative free cash flow, its first cash-flow-negative quarter as a public company.
The user counts are racing up; the question investors will keep asking is when the spending starts to pay for itself.
