Can I run Falcon-H1-34B-Instruct on Apple M4 Pro (48GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs usable speed ~12 tok/s est.

Yes. Falcon-H1-34B-Instruct runs on Apple M4 Pro (48GB) at Q4_K_M (~21.1 GB of ~32 GB usable).

Needs ~21.1 GB Device usable ~32 GB

Runs at Q4_K_M using ~21.1 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 ~10.9 GB of headroom.

Pays for itself after
~239,900M tok

At ~$0.15/kWh and the estimated ~12 tok/s, a million generated tokens costs about $0.49 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$2,399 Apple M4 Pro (48GB) pays for itself after roughly 239,900 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

FAQ

Can Apple M4 Pro (48GB) run Falcon-H1-34B-Instruct?

Yes. Falcon-H1-34B-Instruct runs on Apple M4 Pro (48GB) at Q4_K_M (~21.1 GB of ~32 GB usable).

How much memory does Falcon-H1-34B-Instruct need?

Apple M4 Pro (48GB) has room to spare. At Q4_K_M the weights are ~18.94 GB; with KV cache and runtime overhead, budget ~21.1 GB at a 4k context.

What is the best tool to run Falcon-H1-34B-Instruct 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.
