Google will begin testing a new artificial intelligence search mode that lets users ask questions that are made up of multiple parts. The new feature, called "AI Mode," can run multiple related searches simultaneously in the background, guessing which subtopics users will be interested in next, and then giving a comprehensive answer that summarizes multiple questions, said Robby Stein, Google's vice president of search products. The feature will run in a separate tab, suitable for handling more complex queries. Early tests have shown that queries in AI Mode take twice as long as regular searches. Stein said the feature lets users get information on the web and all of Google's new information systems. AI Mode, which can process text, images and video and runs on Gemini 2.0, Google's latest flagship AI model, will first be available to users who pay for Google's artificial intelligence subscription package.
