Will Apple Intelligence work on older iPhones?

Mostly no. On iPhones, Apple Intelligence is limited to newer models with the required hardware, so most older iPhones won’t support it.

The practical rule is:

• Supported: iPhone 15 Pro and later models that meet Apple’s hardware requirements
• Not supported: iPhone 15 and iPhone 15 Plus, and most older iPhones

Apple Intelligence depends on newer chips and enough memory for on-device AI features, so if you have an older iPhone you should assume it won’t work unless Apple’s official compatibility list says your exact model is supported.

Older iPhones may still get normal iOS updates, but they won’t get the full Apple Intelligence feature set.

Before relying on this, check your exact model in Settings > General > About and confirm Apple’s current Apple Intelligence compatibility page, since exact supported models can change over time and by region.
