Can I run Hunyuan-A13B-Instruct on Apple M5 Max (128GB)?

Compatibility verdict VRAM threshold engine

Yes, it runs GPU accelerated

Yes. Hunyuan-A13B-Instruct runs on Apple M5 Max (128GB) at Q4_K_M (~48.3 GB of ~96 GB usable).

Needs ~48.3 GB Device usable ~96 GB

Runs at Q4_K_M using ~48.3 GB of ~96 GB usable. You have room for Q8_0 for higher quality.

That figure is at a 4k context and moves about ±15% as context length changes. Apple M5 Max (128GB) leaves ~47.7 GB of headroom, room to step up to Q8_0 for higher quality.

FAQ

Can Apple M5 Max (128GB) run Hunyuan-A13B-Instruct?

Yes. Hunyuan-A13B-Instruct runs on Apple M5 Max (128GB) at Q4_K_M (~48.3 GB of ~96 GB usable).

How much memory does Hunyuan-A13B-Instruct need?

Apple M5 Max (128GB) has room to spare. 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.

Sources

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.
