To ensure quality, CoPilot is given test questions, and its responses are evaluated based on criteria such as accuracy, relevance, tone, and intelligence. Those evaluation scores are then used to improve the model. It’s important to keep in mind that the system was designed to mimic natural human communication, but the output may be inaccurate, incorrect, or out of date. Providing feedback via the Thumbs Up and Thumbs Down icons will aid in teaching CoPilot which responses are and are not helpful to you as a user. We will use this feedback to improve it, just like we use customer feedback to improve other Microsoft 365 services and Microsoft 365 apps. We don’t use this feedback to train the foundation models used by CoPilot. Customers can manage feedback through admin controls.
