Google's chatbot is closing in on OpenAI. Alphabet just reported its Q3 earnings, and announced that its Gemini App now has 650 million monthly active users. That's a jump up from the 450 million monthly users Google reported in July, and boosted in part by the rollout of its viral image tool, Nano Banana. OpenAI recently said ChatGPT has 800 million weekly users, so it's still ahead of Google, but the latest update shows the Alphabet company is blazing ahead. The latest 650 million monthly user update was just one of the eye-popping numbers in Google's earnings, which made the company's first-ever $100 billion quarter. Google reported a record $102.35 billion in revenue and a healthy beat in its Cloud business, which is a spot that investors are especially focused on amid heavy AI spending. The Search business, meanwhile, raked in $56.56 billion in revenue — a 15% year-on-year jump. Google also said it expects to spend more on capex than previously projected.
