- Gemini 3 is now the default model behind AI Overviews in Google Search worldwide.
- Users can now ask follow-up questions directly from AI Overviews without leaving the search page.
- Google is moving toward a more conversational search experience that combines quick answers with deeper exploration.
Google is expanding how people interact with Google AI Search by making it easier to move from quick answers to deeper conversations with artificial intelligence. The company has announced two major updates. First, making Gemini 3 the default model powering AI Overviews. Second, users can ask follow-up questions directly from those summaries, without having to reinitiate the conversation.
Gemini 3 now powers AI overviews worldwide
For those unaware, AI Overviews are the short, AI-generated summaries that appear at the top of Google Search results for certain queries. Google says these summaries are now powered globally by Gemini 3, its latest large language model.
According to the company, Gemini 3 offers stronger reasoning and improved response quality, helping AI Overviews deliver clearer and more useful explanations directly on the results page. The goal is to give users faster access to helpful context, particularly when a topic is too detailed for a simple one-line answer.
By standardizing Gemini 3 across AI Overviews, Google is also aligning the technology behind quick summaries with the same model used in its broader conversational search features.
Follow-up questions bring Google AI Search closer to real conversation
One of the most noticeable updates is how easily users can now continue asking questions. Instead of switching to a separate interface, people can tap directly from an AI Overview into a follow-up conversation using AI Mode while keeping the original context intact.
This means users no longer need to rephrase or restate their question to get more detail. The system already understands what the conversation is about and can respond accordingly, creating a smoother transition from short answers to more in-depth discussion.
Google says internal testing showed that users prefer this kind of continuous flow, especially when researching topics that require several steps or clarifications.

Industry attention and broader implications
The updates have drawn attention across the tech industry, as they continue to blur the line between traditional search engines and AI chat platforms. Analysts note that while conversational search could improve user satisfaction, it may also change how people interact with websites and content publishers.
Questions about traffic patterns, advertising models, and content visibility are already part of ongoing discussions around AI-driven search. Google has not announced changes to ranking systems or monetization tied specifically to these features, but the company has acknowledged that Search is expanding as user behavior changes.
For now, Google says the rollout is global on mobile, with further expansion expected across devices and regions over time.
