Google Makes Gemini 3 the Default Model for AI Overviews

Gemini 3 Becomes Standard for AI Overviews

Google has begun rolling out two upgrades for Search. Starting today, Gemini 3 is the default model powering AI Overviews. When the company debuted its new family of AI systems last November, it first deployed Gemini 3 in AI Overviews through a router that was programmed to direct the most difficult questions to the new system. Now Google is making Gemini 3 the standard for all users globally. In practice, Gemini 3 should prove better at generating more credible and relevant summaries.

Seamless Transition to AI Mode Conversation

The second upgrade lets users jump directly into an AI Mode conversation from an AI Overview. Google first previewed this feature late last year. “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.” On mobile devices, the new capability is available immediately, allowing a direct transition from an AI Overview to a conversational interface.
