Probably AI based
OpenAI wants to try its hand at a new area and compete with Google itself. OpenAI is reportedly already working on its own search engine.
OpenAI's search engine may be partially based on Microsoft Bing, which is not surprising given the close cooperation between the companies. At the same time, it is very likely that the OpenAI search engine will be based on some kind of artificial intelligence system, which will help the new system stand out from its competitors.
Unfortunately, there are no details yet, but work on the search engine certainly could not have started for a long time, so, apparently, the solution will not be released in the near future. In addition, the search engine market is very specific, and on a global scale no one can yet compete with Google even approximately.
