Can I run Hunyuan-A13B-Instruct on Apple M4 (16GB)?

Compatibility verdict VRAM threshold engine

No, not enough memory would not load

No. Hunyuan-A13B-Instruct needs ~48.3 GB even at Q4_K_M, but Apple M4 (16GB) only has ~10.5 GB usable.

Needs ~48.3 GB Device usable ~10.5 GB

Needs ~48.3 GB even at Q4_K_M, but only ~10.5 GB is usable.

That figure is at a 4k context and moves about ±15% as context length changes.

The gap is about 37.8 GB: Hunyuan-A13B-Instruct needs roughly 48.3 GB at Q4_K_M and Apple M4 (16GB) leaves only about 10.5 GB usable for a model. The lightest tracked hardware that runs Hunyuan-A13B-Instruct is the Apple M4 Max (128GB) at 128 GB. See Hunyuan-A13B-Instruct on Apple M4 Max (128GB).

FAQ

Can Apple M4 (16GB) run Hunyuan-A13B-Instruct?

No. Hunyuan-A13B-Instruct needs ~48.3 GB even at Q4_K_M, but Apple M4 (16GB) only has ~10.5 GB usable.

How much memory does Hunyuan-A13B-Instruct need?

Apple M4 (16GB) does not have enough memory. At Q4_K_M the weights are ~45.43 GB; with KV cache and runtime overhead, budget ~48.3 GB at a 4k context. It is a Mixture-of-Experts model (80B total / 13B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run Hunyuan-A13B-Instruct 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.
