Microsoft has introduced a feature called “Deep Search” for its Bing search engine, powered by OpenAI’s GPT-4. The feature enhances the search experience by providing more relevant and comprehensive answers to complex queries. While Deep Search builds on Bing’s existing web index and ranking system, it utilizes GPT-4 to expand search queries into a more detailed description of the desired results. By considering millions of web pages and leveraging GPT-4’s capabilities, Deep Search aims to offer curated and informative results, ranking them based on relevance, credibility, freshness, and popularity. The feature may take up to 30 seconds to complete but aims to provide users with specific and comprehensive answers. GPT-4 is already integrated into various aspects of Bing, such as Copilot and web result ranking.
