Google Makes Gemini 3 the Default Model for AI Overviews
Google said Gemini 3 would power AI Overviews by default and add follow-up conversations directly inside Search.
Google announced that Gemini 3 would become the default model behind AI Overviews and that people could ask follow-up questions directly from the overview. The change pushed Search further toward a conversational experience rather than a page of links alone.
For publishers and AI product teams, the update made distribution through answer interfaces more central. Search still points users to the web, but the product increasingly decides which context is summarized first and which questions are carried into a longer interaction.
