While it is necessary to power some AI apps, it isn't an essential service like other system apps. Tap AICore. Uninstalling AICore cleared 7GB of data from my phone's storage. If, like me, you avoid using AI features, you should uninstall AICore, as you will not lose anything you care about. So, unless you regularly use your Android phone's AI models, uninstall AICore to free up its storage and reduce bothersome AI notifications.
