Can BING be trained repeatedly to produce more and more accurate results?

Hi michael1900, if you are looking to train a model on your own indexed sources, we recommend Microsoft 365 Copilot as Bing Chat Enterprise does not access Microsoft Graph data. If you use Bing Chat Enterprise, you will need to provide information as part of your chat queries to help it generate responses with the desired information and voice. Additionally, if you use Copilot in Microsoft Edge by selecting the Copilot button in the top right of the Edge UI, BCE can read context for the open webpage when generating a response (such as using your official website). For more information on this, please see our documentation: https://learn.microsoft.com/bing-chat-enterprise/edge
