Google first announced this for AI Mode results in November. In December, it began using Gemini 3 Flash for AI Mode. Now, Google is bringing Gemini 3 Pro to AI Overviews for complex queries.
Gemini 3 Pro generates AI Overviews for complex English queries worldwide and is available to Google AI Pro and 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. Google’s AI Overviews today may look different from how they did just a week ago. Google will keep improving its Gemini models and rolling those upgrades into Search, including AI Overviews and AI Mode.
