What happened
Google integrated Gemini 3.5 Flash as the new default model in AI Mode globally, marking Search's largest overhaul in over 25 years. This upgrade introduces a multi-modal AI-powered Search box, accepting text, images, files, videos, or Chrome tabs. Google also launched "Search agents," enabling users to create and manage AI agents for 24/7 information monitoring (for AI Pro & Ultra subscribers), expanded booking capabilities (US), and free generative UI/coding dashboards (all users) this summer. AI Mode now serves over one billion monthly users, with queries doubling quarterly.
Why it matters
Search's evolution from keyword-based retrieval to proactive, agentic task completion fundamentally alters user interaction with information and services. Procurement teams face new evaluations for search infrastructure, while platform engineers must prepare for integrating agentic workflows. This follows Siteimprove's February 2026 expansion of its agentic content intelligence platform, indicating a broader industry pivot towards autonomous AI assistance. Founders should recognise the emerging paradigm of persistent, personalised AI agents as a new product surface.
