Can I run Ornith 1.0 9B on Apple M5 Max (128GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs GPU accelerated ~88 tok/s est.

Yes. Ornith 1.0 9B runs on Apple M5 Max (128GB) at Q4_K_M (~7.1 GB of ~96 GB usable).

Needs ~7.1 GB Device usable ~96 GB

Runs at Q4_K_M using ~7.1 GB of ~96 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. Apple M5 Max (128GB) leaves ~88.9 GB of headroom, room to step up to FP16 for higher quality.
