Google has introduced a new experimental feature called AI Mode in its Search Labs, which allows users to ask complex, multi-part questions and receive detailed AI-powered responses. This feature uses a custom version of the Gemini 2.0 model to provide advanced reasoning and multimodal capabilities. AI Mode can handle nuanced questions that previously required multiple searches and offers follow-up questions for deeper exploration. Additionally, AI Overviews have been upgraded with Gemini 2.0 to provide faster and higher-quality responses for coding and advanced math.
