Google Search adds AI agents, generative UI, and conversational search box powered by Gemini 3.5 Flash

Google announced major updates to Search at I/O 2026, with AI Mode now powered by Gemini 3.5 Flash globally and serving over 1 billion users monthly.

Intelligent search box redesign

Google is rolling out what it calls the "biggest upgrade to [the] Search box in over 25 years." The new intelligent search box expands as users type, reflecting a shift toward longer, more conversational queries. The redesign includes AI-powered query suggestions that go beyond autocomplete by anticipating user intent.

Below the text box, users get shortcuts to AI Mode, Talk (Search Live), and Create (Nano Banana in Google Lens). A plus menu allows uploading images from gallery or camera, plus document files directly into queries. This rollout began May 19, 2026.

Google is also deploying a seamless transition between AI Overviews and AI Mode when users tap "Show more" on results pages.

Information agents for paid subscribers

Google announced "information agents" that run continuously in the background, monitoring the web 24/7 for changes related to user-specified queries. According to Google, these agents scan "everything on the web, like blogs, news sites and social posts, plus our freshest data, such as real-time info on finance, shopping and sports."

Use cases include apartment hunting—where users can specify exact requirements and receive notifications when matching listings appear—and tracking product drops from favorite athletes or brands.

Information agents will be available to Google AI Pro and Ultra subscribers this summer.

Generative UI and custom mini-apps

Google announced "agentic coding in Search" that will use the latest Gemini models and a technology called Google Antigravity to build custom dynamic layouts and interactive visuals. The system assembles components like interactive visuals, tables, graphs, and simulations in real-time.

This generative UI capability will be free for all users this summer.

Search will also build custom dashboards and trackers for ongoing tasks like wedding planning or home moves. Google describes these as "mini apps for your own specific tasks." These mini-apps will launch in coming months for AI Pro and Ultra subscribers in the US only.

What this means

Google is rapidly expanding its paid AI subscription offerings, with information agents and custom mini-apps joining the premium tier. The shift toward background monitoring and continuous task management represents a move from query-response to persistent assistance. The Gemini 3.5 Flash deployment to 1 billion monthly users marks significant scale for Google's AI infrastructure, though the company hasn't disclosed context window sizes, pricing details, or benchmark performance for this model variant in the Search context.
