Google makes Gemini 3 the default model for AI Overviews globally
Google has begun rolling out two upgrades to Search. Starting today, Gemini 3 serves as the default model powering AI Overviews for all users globally, while mobile users gain direct access to AI Mode conversations from AI Overviews.
Google introduced its new family of AI systems last November. At that time, the company deployed Gemini 3 in AI Overviews using a router programmed to direct the most difficult questions to the new system. This approach limited initial exposure to complex queries. Now, Google expands Gemini 3 to become the standard model across all AI Overviews worldwide.
Gemini 3 generates summaries that demonstrate improved credibility and relevance compared to prior models. The upgrade applies universally, ensuring consistent performance for every user interaction with AI Overviews.
The second upgrade enables users to transition directly into an AI Mode conversation from any AI Overview. Google first previewed this capability late last year during testing phases.
“In our testing, we’ve found that people prefer an experience that flows naturally into a conversation — and that asking follow‑up questions while keeping the context from AI Overviews makes Search more helpful,” said Robby Stein, vice president of product for Google Search. “It’s one fluid experience with prominent links to continue exploring: a quick snapshot when you need it, and deeper conversation when you want it.”
This direct jump into AI Mode preserves the original context from the AI Overview, supporting seamless follow-up questions. The feature rolls out starting today specifically for users accessing Google Search on mobile devices.
