Two Questions, Not One
"Is my device supported?" and "will my device get the features?" have had different answers since Apple Intelligence arrived. A phone can sit comfortably on the compatibility list and still never show a single AI feature, because those run on-device and need silicon the older models do not have. On iPhone the line is the A17 Pro; on iPad it is the M1 and the A17 Pro; on Mac it is Apple silicon with enough memory. Each page below answers both questions for one specific model.
There is a third question that matters just as much and rarely gets asked: should you install it? A 2020 iPhone with a degraded battery and 64 GB of storage will technically run this year's beta, and will do it badly — not because the software is broken, but because a beta's first-week indexing costs more on hardware that has none to spare. Every model page states the memory, the storage tiers and the thermal behaviour that actually decide how the beta feels, rather than just repeating whether the name appears on Apple's list.
If your model is not listed as supported, no file changes that. Beta profiles stopped existing in 2023, and even before then a profile only revealed betas your hardware already qualified for — it never unlocked an unsupported device. The compatibility check happens in the installer, against the device model itself.
