Can I run Apple OpenELM 3B on iPhone Air?
Yes. Apple OpenELM 3B runs on iPhone Air at Q4_K_M (~3 GB of ~8 GB usable).
Runs at Q4_K_M using ~3 GB of ~8 GB usable. You have room for FP16 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. iPhone Air leaves ~5 GB of headroom, room to step up to FP16 for higher quality.
