Can I run Magistral Small on iPhone 15 Pro?
No. Magistral Small needs ~16 GB even at Q4_K_M, but iPhone 15 Pro only has ~4.5 GB usable.
Needs ~16 GB even at Q4_K_M, but only ~4.5 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 11.5 GB: Magistral Small needs roughly 16 GB at Q4_K_M and iPhone 15 Pro leaves only about 4.5 GB usable for a model. The lightest tracked hardware that runs Magistral Small is the Apple M4 (24GB) at 24 GB. See Magistral Small on Apple M4 (24GB).

iPhone 15 Pro does not have enough memory. At Q4_K_M the weights are ~14 GB; with KV cache and runtime overhead, budget ~16 GB at a 4k context.
What is the best tool to run Magistral Small on iOS?
On iPhone and iPad, Apple Foundation Models (Built into iOS 26, ~3B on-device model, zero download, fully private.) is the standard choice. Phones realistically run 1B-4B class models. Anything larger thermally throttles or OOMs.
