Summary
Google's AI assistant, Gemini, has reached one billion monthly users, making it the company's fastest-growing product to date, according to CEO Sundar Pichai. This achievement arrives amid a substantial restructuring of Google's AI division, marked by leadership shifts like Demis Hassabis stepping away from daily operations at Google DeepMind and the departure of veteran engineer Jeff Dean. Despite delays in launching the flagship Gemini 3.5 Pro model and strong competition in areas like code generation, Google continues to leverage its massive audience by embedding AI across its ecosystem, paralleling OpenAI's recent announcement of reaching one billion users in July.
