Different features take different paths
Apple Intelligence is not one processing model. Some features run entirely on device, some use Private Cloud Compute, and some invoke a third-party service after an explicit prompt.
Blanket statements about what happens to your photos are therefore wrong in both directions. The specific feature and the specific user action determine the path.
Library indexing is not model training
Photos has performed on-device analysis for years — recognising faces, scenes, and text so search works. That indexing is local and predates Apple Intelligence.
Conflating it with sending images to a model for training is a common error. They are different mechanisms with different data flows, and treating them as one prevents an accurate assessment of either.
Third-party extensions are an explicit step
Where a request is handed to an external service, that is a distinct action with its own prompt and its own privacy terms.
Knowing when that boundary is crossed matters more than a general position on AI features, because it is the point at which content leaves Apple's stated handling.
A workable approach
- Review Apple Intelligence and Siri settings, and which features are available on your device.
- Understand when an external extension is invoked, and what prompt indicates it.
- Read the current documentation for the specific feature rather than generalising.
- Keep genuinely sensitive media out of workflows you do not actually need.
Two errors in either direction
- Making blanket claims about all AI photo processing being local, or all of it being uploaded.
- Confusing on-device library indexing with public model training.
Why a vault sidesteps the question
Content held in a separate encrypted vault is not in the Photos library, so library-level analysis features do not apply to it at all.
That is a structural answer rather than a settings answer, which is useful precisely because feature behaviour changes between operating-system releases.
A fictional example
Noah starts with a non-sensitive test: “Review Apple Intelligence & Siri settings and feature availability.” Next, Noah follows the second check: “Understand when ChatGPT or another extension is invoked.” This fictional scenario demonstrates the decision process; it is not a report of product testing.

Can I disable features I do not want?
Apple exposes controls for Apple Intelligence and app integrations; exact options depend on device, region, and release.
