Gemini 3 Used in Select AI Mode Searches

Google has begun integrating its latest AI model, Gemini 3, to enhance responses in AI Mode for certain search queries. This development was expected following the announcement of Gemini 3 last week, and it is now live for a limited group of users within Google Search.

Availability and Eligibility

At present, Gemini 3 in AI Mode is available exclusively to U.S.-based subscribers of Google AI Pro and Ultra. Users can identify whether they have access by checking for the Gemini 3 toggle within the AI Mode tab of their search interface.

Official Announcement

Nick Fox, Google’s Senior Vice President of Knowledge and Information, confirmed the rollout on X:
“The rollout of Gemini 3 in Search continues! We’ve just shipped intelligent automatic model routing to Gemini 3 Pro for your toughest questions in AI Mode.”

Clarification on AI Overviews

Previously, Fox had indicated that Gemini 3 would also be used in AI Overviews. However, his latest update clarified that the model is currently applied solely within AI Mode, and not in AI Overviews.

Intelligent Model Routing

Gemini 3 introduces an advanced system of automatic model routing. This allows the most challenging queries in AI Mode to be handled by Gemini 3 Pro, optimising both the accuracy and depth of responses.

Enhancing Search Experience

For subscribers, this update means more detailed and visually enriched answers. Users may notice clearer explanations, improved context understanding, and a higher degree of helpfulness in AI-generated content.

Background of Gemini 3

Gemini 3 was officially unveiled on 18 November 2025. Google CEO Sundar Pichai described it as the company’s “most intelligent model,” combining all previous Gemini capabilities to allow users to explore ideas more effectively.

Benefits for Users

The deployment of Gemini 3 aims to improve the AI search experience for complex queries. Early users will notice that responses are more informative and visually engaging, offering a richer interface compared to previous models.

Visual and Detailed Responses

Subscribers may see AI-generated responses with enhanced visuals, structured summaries, and clearer guidance. This improvement is particularly noticeable for queries that require multi-step explanations or in-depth analysis.

Limitations of the Rollout

While Gemini 3 is now live in AI Mode, it is currently limited to a small group of U.S. subscribers. Broader availability is expected in the future, likely following further testing and optimisation of the system.

Google’s Commitment to AI

The rollout of Gemini 3 demonstrates Google’s ongoing commitment to improving AI-driven search. By using a highly capable model, the company aims to provide users with faster, more accurate, and contextually relevant results.

Future Upgrades

All AI responses in Google Search are expected to eventually leverage Gemini 3. Over time, Google may introduce newer models or updates that further enhance both AI Mode and AI Overviews.

How to Use Gemini 3

Users with access can toggle Gemini 3 in AI Mode and experience its enhanced capabilities for complex queries. The feature is designed to provide intuitive, high-quality responses without requiring users to adjust settings manually.

Key Takeaways

Gemini 3 represents a significant upgrade in Google’s AI infrastructure. For those in the U.S. with Pro and Ultra subscriptions, it offers a richer, more intelligent AI search experience.

Looking Ahead

As Google continues to refine Gemini 3, more users are expected to benefit from faster, more detailed, and visually enhanced AI Mode results. This rollout marks an important step in the evolution of AI-powered search technology.
