Can I run GLM-4 9B on Apple M3 Pro (18GB)?
Yes. GLM-4 9B runs on Apple M3 Pro (18GB) at Q4_K_M (~7.3 GB of ~12 GB usable).
Runs at Q4_K_M using ~7.3 GB of ~12 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. Apple M3 Pro (18GB) leaves ~4.7 GB of headroom, room to step up to Q8_0 for higher quality.

- Pays for itself after
- ~4,479M tok
At ~$0.15/kWh and the estimated ~14 tok/s, a million generated tokens costs about $0.21 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,299 Apple M3 Pro (18GB) pays for itself after roughly 4,479 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 M3 Pro (18GB) run GLM-4 9B?
Yes. GLM-4 9B runs on Apple M3 Pro (18GB) at Q4_K_M (~7.3 GB of ~12 GB usable).
How much memory does GLM-4 9B need?
Apple M3 Pro (18GB) has room to spare. At Q4_K_M the weights are ~5.82 GB; with KV cache and runtime overhead, budget ~7.3 GB at a 4k context.
What is the best tool to run GLM-4 9B 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.
