Can I run Phi-4-mini-reasoning on Apple M4 (16GB)?
Yes. Phi-4-mini-reasoning runs on Apple M4 (16GB) at Q4_K_M (~3.6 GB of ~10.5 GB usable).
Runs at Q4_K_M using ~3.6 GB of ~10.5 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 M4 (16GB) leaves ~6.9 GB of headroom, room to step up to FP16 for higher quality.

- ~2,323M tok
At ~$0.15/kWh and the estimated ~41 tok/s, a million generated tokens costs about $0.07 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$999 Apple M4 (16GB) pays for itself after roughly 2,323 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 (16GB) run Phi-4-mini-reasoning?
Yes. Phi-4-mini-reasoning runs on Apple M4 (16GB) at Q4_K_M (~3.6 GB of ~10.5 GB usable).
How much memory does Phi-4-mini-reasoning need?
Apple M4 (16GB) has room to spare. At Q4_K_M the weights are ~2.32 GB; with KV cache and runtime overhead, budget ~3.6 GB at a 4k context.
What is the best tool to run Phi-4-mini-reasoning 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.
