Some Google AI Overviews now use Gemini 3 Pro

Google now uses Gemini 3 Pro to generate some AI Overviews in Google Search. Google said for more complex queries Gemini 3 Pro is used for AI Overview.

This was previously announced for AI Mode results back in November and then in December Google began using Gemini 3 Flash for AI Mode. Now, Google is taking Gemini 3 Pro to AI Overviews for complex queries.

Gemini 3 Pro is used to generate AI Overviews for complex queries in English, globally for Google AI Pro & Ultra subscribers.

What Google said. Robby Stein, VP of Product at Google Search wrote:

  • “Update: AI Overviews now tap into Gemini 3 Pro for complex topics.”
  • “Behind the scenes, Search will intelligently route your toughest Qs to our frontier model (just like we do in AI Mode) while continuing to use faster models for simpler tasks.”
  • “Live in English globally for Google AI Pro & Ultra subs.”

Why we care. The AI Overviews may be very different today than it was a week or so ago. Google will continue to improve its Gemini models and work those upgraded models into Google Search, including AI Overviews and AI Mode.
