Google has upgraded its Search platform globally with Gemini 3.5 Flash as its AI Mode user base officially surpassed one billion monthly active users. The overhaul represents the largest functional update to Google's search box in over 25 years, transitioning the tool from indexed web links to dynamic, multi-modal answer generation. Users can now run background search agents, process complex multi-step queries, and generate custom interface tools directly within search results.
Gemini 3.5 Flash Powers Multi-Modal Search Overhaul
The upgraded Search interface uses Gemini 3.5 Flash as the default model in AI Mode across all supported regions. AI Mode has surpassed one billion monthly users just one year after its debut, with query volume doubling every quarter since launch according to Google Search VP Elizabeth Reid.
The reimagined search box dynamically expands to accept text, images, files, videos, and Chrome tabs as input. In addition to multi-modal inputs, Search now supports continuous conversational back-and-forth flows directly within AI Overviews, preserving contextual context while recommending relevant source links.
Background Information Agents and Local Calling
Google is introducing 24/7 autonomous information agents that monitor web data continuously for specific queries. Key features announced during the presentation include:
- Continuous web scanning across news sites, social posts, blogs, and real-time financial or sports feeds
- Automated notification alerts when specific criteria (like real estate listings or retail drops) are met
- Expanded local booking services, including agentic phone calls to businesses for service inquiries like home repair and pet care in the U.S.
- Secure integration of Personal Intelligence across Gmail, Google Photos, and upcoming support for Google Calendar across 98 languages
However, full access to continuous background monitoring and mini-app generation is initially limited to paid Google AI Pro and Ultra subscribers, leaving free-tier users with basic conversational Search tools.
Real-Time Code Generation via Google Antigravity
By incorporating Google Antigravity alongside Gemini 3.5 Flash, Search can now code custom generative user interfaces on the fly. Rather than displaying standard web pages, Search builds interactive simulations, custom data tables, and persistent tracking dashboards based on user prompts.
These generated mini-apps pull real-time data from map layers, weather services, and local reviews to assist users with ongoing projects like event planning or personal fitness tracking.
