Google is rolling out a significant upgrade to AI Overviews, its artificial intelligence-powered search feature. The upgrade involves the integration of Gemini 3 models, with the aim of improving the quality of responses and making the interaction more natural and conversational.

Gemini 3: a more versatile model

The Gemini 3 family of models offers several variants, each optimized for specific types of tasks. Google says that AI Overviews will dynamically select the most appropriate Gemini 3 model based on the complexity of the query. For simple searches, Gemini 3 Flash, a lighter and more efficient version, might be used. For more complex queries that require deeper reasoning, AI Overviews might opt for Gemini 3 Pro (available to paying subscribers).

Implications for users

This upgrade aims to address some of the criticisms leveled at AI Overviews, which in the past has shown inaccuracies in its responses. The use of Gemini 3, with its greater ability to understand natural language and reasoning, should lead to more accurate and relevant results. It remains to be seen how this will translate into an improved user experience, but Google's approach seems promising.
