Google has launched Gemini 3, its most advanced AI model yet, into Search’s AI Mode, marking the first time a Gemini model is available on launch day in Search. Available now to Google AI Pro and Ultra subscribers in the U.S., users can select Gemini 3 Pro under the “Thinking” model option in AI Mode. Google plans to broaden access to all U.S. users shortly, with increased usage limits for premium subscribers.
Advanced Reasoning and Multimodal Understanding
Gemini 3 boasts cutting-edge reasoning capabilities and deep multimodal understanding. It is designed to handle complex questions, clarify advanced topics, and support interactive visuals directly within AI Mode responses. Rather than just delivering text, Gemini 3 dynamically generates customized response layouts, including images, tables, and structured elements, crafting answers that are clearer and more engaging.
Upgraded Query Fan-Out for Better Search Results
With an enhanced query fan-out technique, Gemini 3 can perform more simultaneous, contextually relevant searches. This enables Search to capture content it might have missed previously, providing richer results tailored to user queries. Google’s VP and GM of Search, Robby Stein, highlighted that Gemini 3 improves understanding of user intent, helping surface additional valuable web content.
Generative User Interface Innovations
Gemini 3 introduces generative UI features that produce dynamic, visually-rich responses. The model can analyze queries and produce tailored interactive tools, such as a three-body physics simulator or custom mortgage calculators, embedded directly into answers. All responses include prominent links to reputable web sources, facilitating easy access to supporting materials.
Implications for Content Discovery
These updates alter how content is surfaced and displayed in AI Mode, potentially affecting how sites are cited during extended or intricate searches. The new visual and interactive designs may compete with traditional search interfaces, influencing the visibility of content beyond ranking positions. As Gemini 3 becomes more widely available, content creators should monitor how their works are incorporated into AI-generated answers.
Looking Forward
Google plans to continue refining Gemini 3 based on user feedback. An automatic model selection feature is forthcoming for Google AI Pro and Ultra subscribers, intelligently routing complex queries to Gemini 3 while employing faster models for simpler tasks. Broader access to Gemini 3 in AI Mode across the U.S. is anticipated, but has no confirmed schedule yet.
