Can I run Granite 4.1 30B on iPhone 17?
No. Granite 4.1 30B needs ~19.1 GB even at Q4_K_M, but iPhone 17 only has ~4.5 GB usable.
Needs ~19.1 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 14.6 GB: Granite 4.1 30B needs roughly 19.1 GB at Q4_K_M and iPhone 17 leaves only about 4.5 GB usable for a model. The lightest tracked hardware that runs Granite 4.1 30B is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Granite 4.1 30B on Nvidia GeForce RTX 4090 (24GB).
