Imagine you're at a buffet with three different lines to choose from, each offering a different dining experience. The first line is like the "Auto" mode in the new Microsoft Copilot feature using the GPT-5 Model Selector. Here, the chef decides how much time to spend preparing your meal based on what you order. It's a balanced approach where you get a meal that's well-prepared without having to wait too long.

The second line is similar to the "Instant" mode. This is like grabbing a quick snack. You get something fast, like a sandwich or a salad, which is perfect when you're in a hurry and just need something to keep you going. The responses are quick, and you get what you need without any delay.

The third line represents the "Thinking" mode. Here, you choose a gourmet meal that takes a bit longer to prepare, but the result is a more refined and satisfying dish. This is for when you have the time and want something more substantial, where the chef takes extra care to ensure the flavors are just right.

In the context of Microsoft Copilot, these modes give users control over how much "thinking" the system does. The "Auto" mode is the default, where the system decides the best approach. "Instant" mode is for when you need quick answers, like in a chat. "Thinking" mode is for when you want the system to take its time to provide a more detailed and thoughtful response. This flexibility allows users to tailor their experience based on their immediate needs, much like choosing the right line at a buffet depending on how much time and hunger they have.
