What happens to Apple Intelligence features after you delete its on-device models? Apple’s documented way to remove those models is to turn Apple Intelligence off. While it is off, you should expect Apple Intelligence-dependent features to be unavailable. Turn it on again and the models start downloading; how long that takes varies.

How to remove the on-device models

Apple says that turning Apple Intelligence off removes its on-device models. Its support instructions do not describe a separate manual model-deletion option. To remove them, switch Apple Intelligence off in Settings.

Apple’s support article, “How to get Apple Intelligence,” gives the removal and re-download guidance.

What happens to Apple Intelligence features while it is off?

Plan on Apple Intelligence-dependent features being unavailable while Apple Intelligence is off. Apple lists capabilities such as Writing Tools, summaries, image features, translation, Siri enhancements, and notification features, but does not document the effect of model removal on each one individually or map every feature to its on-device and server-side dependencies. That means it would be too broad to say that every server-assisted feature necessarily stops in precisely the same way.

What happens when you turn it on again?

How much storage will turning it off free?

Apple does not give a per-device estimate of the storage you will recover. Its published figures are storage requirements, not a promise that turning the feature off will free that exact amount on your device.
