Can I run Qwen2.5 72B on Apple M4 Pro (48GB)?
No. Qwen2.5 72B needs ~50.2 GB even at Q4_K_M, but Apple M4 Pro (48GB) only has ~32 GB usable.
Needs ~50.2 GB even at Q4_K_M, but only ~32 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 18.2 GB: Qwen2.5 72B needs roughly 50.2 GB at Q4_K_M and Apple M4 Pro (48GB) leaves only about 32 GB usable for a model. The lightest tracked hardware that runs Qwen2.5 72B is the Apple M4 Max (128GB) at 128 GB. See Qwen2.5 72B on Apple M4 Max (128GB).

FAQ
Can Apple M4 Pro (48GB) run Qwen2.5 72B?
No. Qwen2.5 72B needs ~50.2 GB even at Q4_K_M, but Apple M4 Pro (48GB) only has ~32 GB usable.
How much memory does Qwen2.5 72B need?
Apple M4 Pro (48GB) does not have enough memory. At Q4_K_M the weights are ~47.42 GB; with KV cache and runtime overhead, budget ~50.2 GB at a 4k context.
What is the best tool to run Qwen2.5 72B 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.
