Google Search no longer resembles the classic version many of us know, and at I/O 2026 the company embraced this shift wholeheartedly. The developer conference in Mountain View, California, served as the clearest declaration of the direction for its flagship service: moving away from the 25‑year‑old blue‑link format toward a conversational AI‑driven experience.
The roll‑outs included making Gemini 3.5 Flash the default engine behind AI Mode worldwide and a total redesign of the search box, which Google billed as the most significant interface upgrade in over two decades.
Until now, AI in Search appeared as “AI Overviews” and a separate AI Mode that felt more like chatting with the Gemini bot. The new interface will adapt to the tone and intent of your query, featuring an “intelligent search box” that supports longer, more intricate questions.
AI enhancements coming to Search
Robby Stein, Google’s vice‑president of product for Search, framed the I/O announcements as a major leap in blending Search with advanced AI, tracing the evolution from AI Overviews to AI Mode and now a unified AI search experience. He noted that a billion users engage with Google’s AI Mode each month, asking it increasingly complex questions. These tools let people pose virtually any query and receive rich, real‑time answers drawn from Google’s vast knowledge base.
«This is a very exciting time for Search,» Stein told reporters ahead of I/O. «People can ask really anything on their mind and people’s curiosity is fairly endless.»
Google is doubling down on pairing cutting‑edge AI models with live data—web pages, business listings, products, images, finance—to deliver deeper, conversational results.
The company also announced the rollout of Gemini 3.5 Flash, a more capable model focused on reasoning, coding, and complex tasks. Stein said that building Search tools around this new model lifts the overall quality of answers.
Handling more complex queries
Alongside the model upgrade, Google is launching an “intelligent search box” that expands for lengthy queries, accepts uploads (photos, PDFs), auto‑completes nuanced prompts, and can pull context from open Chrome tabs to support multi‑step research.
AI Overviews now flow seamlessly into AI Mode for follow‑ups, allowing users to continue a conversation with the AI while it presents search results.
Stein also unveiled dynamic, interactive “widgets” and larger “super widgets” generated by the system (powered by Gemini and developer tools). These can simulate physics, visualize concepts, act as calculators, or become persistent mini‑apps for tasks such as moving, health tracking, or trip planning—optionally leveraging personal data (Gmail, Photos, Calendar) to personalize results across 200 markets and 98 languages.
He described Search entering an “agentic” era where AI agents assist with a range of duties, from monitoring topics and sending alerts (e.g., when a favorite artist announces a tour) to helping with bookings. While the agent won’t finalize a reservation on your behalf, you can provide details—preferred dates, times, party size—and receive a curated list of options with up‑to‑date availability, pricing, and links to complete the booking. These features are slated for a summer release.
