It seems you are experiencing frustration with the current modes available in Copilot. As per the information available, Copilot Chat offers different modes tailored to user needs, including a "Quick response" mode for common or routine questions. This mode prioritizes speed and provides succinct responses. If you feel that the other modes are not meeting your expectations, it might be worth exploring the model selector to switch back to the "Quick response" mode if it's available.
Additionally, it's important to note that AI responses can sometimes vary due to their probabilistic nature, which may lead to different answers for the same question. This variability is a characteristic of AI systems designed to provide flexible and contextually relevant responses.
If you have specific feedback or issues, consider providing that feedback directly within the Copilot interface to help improve the experience.
