Can I run Qwen3 32B on Apple M4 (24GB)?
No. Qwen3 32B needs ~22 GB even at Q4_K_M, but Apple M4 (24GB) only has ~16 GB usable.
Needs ~22 GB even at Q4_K_M, but only ~16 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 6 GB: Qwen3 32B needs roughly 22 GB at Q4_K_M and Apple M4 (24GB) leaves only about 16 GB usable for a model. The lightest tracked hardware that runs Qwen3 32B is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Qwen3 32B on Nvidia GeForce RTX 4090 (24GB).

FAQ
Can Apple M4 (24GB) run Qwen3 32B?
No. Qwen3 32B needs ~22 GB even at Q4_K_M, but Apple M4 (24GB) only has ~16 GB usable.
How much memory does Qwen3 32B need?
Apple M4 (24GB) does not have enough memory. At Q4_K_M the weights are ~19.8 GB; with KV cache and runtime overhead, budget ~22 GB at a 4k context.
What is the best tool to run Qwen3 32B 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.
