100-word summary
Google just launched Gemini 3.1 Pro in preview, and it deliberately trades speed for smarter answers. Built on Gemini 3 Deep Think, it adds extended reasoning to handle multi-step problems that would trip up faster models. Think planning a cross-team project or debugging gnarly code, not just answering trivia. It's rolling out now through Vertex AI for businesses and the Gemini app for consumers. Google also shipped Nano Banana 2, which generates marketing images grounded in real-time web knowledge. The twist? Google is betting that taking a few extra seconds to think will matter more than shaving milliseconds off replies.
