New Gemini 3.5 Pro, the fast version flash is already free in the Gemini app and Google search and it's already beating last year's top model. So, how good is the smart one? Here's what makes Gemini 3.5 Pro wild. First, memory. It can hold around 2 million tokens at once. Second, deep think mode. It slows down, works through hard problems step-by-step, and checks its own work. Third, agents. It doesn't just answer questions, it does the work, builds the landing page, tests it, fixes it, and hands it back while you grab coffee. And the secret weapon, it lives inside search, Gmail, Docs, and Android. Billions of people already there. Google just flips the switch. It's coming soon.
