Google released Gemini 3, its latest AI model, and it is already powering AI Mode in Google Search today. Sundar Pichai wrote Google is shipping Gemini 3 and that includes "Gemini 3 in AI Mode in Search with more complex reasoning and new dynamic experiences." "This is the first time we are shipping Gemini in Search on day one," he added.
AI Mode in Search now uses Gemini 3, this enables "new generative UI experiences like immersive visual layouts and interactive tools and simulations, all generated completely on the fly based on your query," Google explained.
Google wrote:
And in the coming weeks, we’re also enhancing our automatic model selection in Search with Gemini 3. This means Search will intelligently route your most challenging questions in AI Mode and AI Overviews to this frontier model — while continuing to use faster models for simpler tasks. This will be rolling out to Google AI Pro and Ultra subscribers in the U.S.
Here is a video of it in action for how RNA polymerase works with generative UI in AI Mode in Search:
Gemini 3 in AI Mode makes for better and more understandable generative layouts, provides more helpful responses, better at responding to your query on the fly, plus more changes will come in the coming weeks for AI Overviews, not just AI Mode, mostly for routing searchers to it via Google Search.

Gemini 3, our most intelligent model, is landing in Google Search today – starting with AI Mode. Excited that this is the first time we’re shipping a new Gemini model in Search on day one! 🚀In Search, Gemini 3 with generative layouts will make it easy to get a rich understanding of anything on your mind. It has state-of-the-art reasoning, deep multimodal understanding and advanced agentic capabilities. That allows the model to shine when you ask it to explain advanced concepts or ideas – it reasons and can code interactive visuals in real-time. It can tackle your toughest questions like advanced science.
Gemini 3 is also making Search smarter by re-architecting what a helpful response looks like. With new generative UI capabilities, Gemini 3 in AI Mode can now dynamically create the overall response layout when it responds to your query – completely on the fly.
And in the coming weeks, we’ll enhance our automatic model selection – meaning Search will intelligently route tough questions in AI Mode and AI Overviews to our frontier model, while continuing to use faster models for simpler tasks.
Under the hood, Gemini 3’s advanced reasoning is giving our query fan-out technique a big boost. It now performs more and much smarter searches because Gemini 3 better understands you. That means Search can now surface even more relevant web content for your specific question.
Gemini 3 Pro is available directly within AI Mode’s drop-down menu, and is rolling out today for Google AI Pro & Ultra subscribers in the U.S, and soon to everyone in the U.S.

A message from Robby Stein from Google:
Starting today, our most intelligent model – Gemini 3 – is bringing incredible reasoning capabilities to Search. This means it can understand your most complex questions and help you find exactly what you need.

Recipe bloggers not happy:
The level of plagiarism this model has reached is now completely out of control. We are going to have to start proactively warning our followers and readers to not use these AI recipes if they find them. This is outrageous!! cc @lilyraynyc @rustybrick https://t.co/phIptrXIR6
