Can I run Ornith 1.0 35B on Apple M4 Pro (48GB)?

Compatibility verdict VRAM threshold engine

Yes, it runs GPU accelerated

Yes. Ornith 1.0 35B runs on Apple M4 Pro (48GB) at Q4_K_M (~23.2 GB of ~32 GB usable).

Needs ~23.2 GB Device usable ~32 GB

Runs at Q4_K_M using ~23.2 GB of ~32 GB usable.

That figure is at a 4k context and moves about ±15% as context length changes. Apple M4 Pro (48GB) leaves ~8.8 GB of headroom.

FAQ

Can Apple M4 Pro (48GB) run Ornith 1.0 35B?

Yes. Ornith 1.0 35B runs on Apple M4 Pro (48GB) at Q4_K_M (~23.2 GB of ~32 GB usable).

How much memory does Ornith 1.0 35B need?

Apple M4 Pro (48GB) has room to spare. At Q4_K_M the weights are ~21 GB; with KV cache and runtime overhead, budget ~23.2 GB at a 4k context. It is a Mixture-of-Experts model (35B total / 3B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run Ornith 1.0 35B on macOS?

LM Studio for a simple setup; mlx-lm for the most speed. vLLM is NOT a Mac tool, it is a CUDA/Linux serving engine. Unified memory is not a fixed VRAM slice; ~70% is usable for weights.

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.
