If it is just a repackaging of ChatGPT's existing "search the web" function, I don't know why they'd bother. It can at best summarize a page of search results for a very literal-minded query, and even then it's often lobotomized by the fact that OpenAI has made it easy for a large number of top websites to opt out of having their pages accessible to their search crawler, which means you're only getting a summary of the search result snippet and metadata. A competent user of Google search can run rings around it in terms of research, even with Google's decline in quality. I guess it makes it faster to answer basic queries for recent information not in the training data, but that hardly seems worthy of a big event.
