Google unveils AI-powered Search with Gemini 3.5 Flash and agentic features

At I/O 2026, Google unveiled a significant enhancement to its Search functionality by making Gemini 3.5 Flash the default model in AI Mode, which boasts over one billion users each month. The Search interface has been revamped to accept various inputs, including text, images, files, videos, and Chrome tabs. This summer, new information agents will be introduced, continuously monitoring web content based on user-defined queries, initially available to Google AI Pro & Ultra subscribers. Additionally, agentic booking will extend to local services, allowing Google to contact businesses for users in specific categories, also launching in the U.S. this summer. Furthermore, agentic coding features, driven by Google Antigravity, will offer custom generative UI, including interactive visuals and dashboards, accessible to all this summer. Personal Intelligence in AI Mode will reach nearly 200 countries and support 98 languages, facilitating secure connections to Gmail, Google Photos, and soon Google Calendar, without requiring a subscription.
