+        To look further ahead into the future, you can increase the [window duration](/docs/alerts/create-alert/create-alert-condition/alert-conditions/#window-duration). A longer window duration directly extends the prediction model’s historical data processing range. For instance, when the window duration is set to 1 minute, the model utilizes historical data from the past 2.5 days to generate predictions.
