In just the last year, Google has radically expanded the number of searches on which you get an AI Overview at the top. Today, the chatbot will almost always have an answer for your query, which has relied mostly on models in Google’s Gemini 2.5 family. There was nothing wrong with Gemini 2.5 as generative AI models go, but Gemini 3 is a little better by every metric.
There are, of course, multiple versions of Gemini 3, and Google doesn’t like to be specific about which ones appear in your searches. What Google does say is that AI Overviews chooses the right model for the job. So if you’re searching for something simple for which there are a lot of valid sources, AI Overviews may manifest something like Gemini 3 Flash without running through a ton of reasoning tokens. For a complex “long tail” query, it could step up the thinking or move to Gemini 3 Pro (for paying subscribers).
