Google rolls out Gemini 3 Flash to AI Mode in Search globally

/dans

Google today began rolling out Gemini 3 Flash as the default model powering AI Mode in Search worldwide. The upgrade brings faster performance and stronger reasoning to AI-generated search responses, Google said.

Why we care. With AI Mode, Google continues to transition toward an AI-first search approach. More queries could be answered directly in AI Mode, reducing reliance on traditional organic listings. Improved reasoning allows AI Mode to handle comparison and planning tasks, multi-intent searches, and research-style queries.

What’s changing. Gemini 3 Flash now powers AI Mode in Search globally.

  • It replaces earlier Flash-class models previously used in AI Mode.
  • AI Mode responses now use Gemini 3-level reasoning with lower latency.

What AI Mode does. According to Google, AI Mode:

  • Breaks complex queries into multiple parts.
  • Pulls real-time information and links from across the web.
  • Presents answers in structured, visually organized formats.
  • Handles multi-step tasks (e.g., trip planning, learning complex topics).

What Google is saying. In a blog post, Tulsee Doshi, senior director, product management, wrote:

Building on the reasoning capabilities of Gemini 3 Pro, AI Mode with Gemini 3 Flash is more powerful at parsing the nuances of your question. It considers each aspect of your query to serve thoughtful, comprehensive responses that are visually digestible — pulling real-time local information and helpful links from across the web. The result effectively combines research with immediate action: you get an intelligently organized breakdown alongside specific recommendations — at the speed of Search.

This shines when tackling complex goals with multiple considerations like trying to plan a last-minute trip or learning complex educational concepts quickly.
