Microsoft is working to incorporate a faster version of OpenAI’s ChatGPT, known as GPT-4, into Bing in the coming weeks in a move that would make the search engine more competitive with Google, according to a new report from Semafor. The integration would see Bing using GPT-4 to answer search queries.

People familiar with the matter told Semafor that the main difference between ChatGPT and GPT-4 is speed. Although ChatGPT sometimes takes a up to a few minutes to form a response, GPT-4 is said to be a lot quicker in responding to queries. The latest software’s responses are also said to be more detailed and more humanlike.
