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.
