Can I run Nemotron 3 Super 120B-A12B on iPhone Air?
No. Nemotron 3 Super 120B-A12B needs ~80.3 GB even at Q4_K_M, but iPhone Air only has ~8 GB usable.
Needs ~80.3 GB even at Q4_K_M, but only ~8 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 72.3 GB: Nemotron 3 Super 120B-A12B needs roughly 80.3 GB at Q4_K_M and iPhone Air leaves only about 8 GB usable for a model. The lightest tracked hardware that runs Nemotron 3 Super 120B-A12B is the Apple M4 Max (128GB) at 128 GB. See Nemotron 3 Super 120B-A12B on Apple M4 Max (128GB).

FAQ
Can iPhone Air run Nemotron 3 Super 120B-A12B?
No. Nemotron 3 Super 120B-A12B needs ~80.3 GB even at Q4_K_M, but iPhone Air only has ~8 GB usable.
How much memory does Nemotron 3 Super 120B-A12B need?
iPhone Air does not have enough memory. At Q4_K_M the weights are ~76.87 GB; with KV cache and runtime overhead, budget ~80.3 GB at a 4k context. It is a Mixture-of-Experts model (120B total / 12B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Nemotron 3 Super 120B-A12B 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.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
