Can I run Qwen3 235B A22B on Apple M4 Max (64GB)?
No. Qwen3 235B A22B needs ~136.9 GB even at Q4_K_M, but Apple M4 Max (64GB) only has ~48 GB usable.
Needs ~136.9 GB even at Q4_K_M, but only ~48 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 88.9 GB: Qwen3 235B A22B needs roughly 136.9 GB at Q4_K_M and Apple M4 Max (64GB) leaves only about 48 GB usable for a model. The lightest tracked hardware that runs Qwen3 235B A22B is the Apple M3 Ultra (256GB) at 256 GB. See Qwen3 235B A22B on Apple M3 Ultra (256GB).

FAQ
Can Apple M4 Max (64GB) run Qwen3 235B A22B?
No. Qwen3 235B A22B needs ~136.9 GB even at Q4_K_M, but Apple M4 Max (64GB) only has ~48 GB usable.
How much memory does Qwen3 235B A22B need?
Apple M4 Max (64GB) does not have enough memory. At Q4_K_M the weights are ~132.39 GB; with KV cache and runtime overhead, budget ~136.9 GB at a 4k context. It is a Mixture-of-Experts model (235B total / 22B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Qwen3 235B A22B 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.
