Can I run Nemotron 3 Nano 4B on iPhone Air?
Yes. Nemotron 3 Nano 4B runs on iPhone Air at Q4_K_M (~3.9 GB of ~8 GB usable).
Runs at Q4_K_M using ~3.9 GB of ~8 GB usable. You have room for Q8_0 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. iPhone Air leaves ~4.1 GB of headroom, room to step up to Q8_0 for higher quality.
