Can I run Hunyuan-A13B-Instruct on 32GB RAM Laptop (CPU/iGPU only)?

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 32GB RAM Laptop (CPU/iGPU only) only has ~28 GB usable.

Needs ~48.3 GB Device usable ~28 GB

Needs ~48.3 GB even at Q4_K_M, but only ~28 GB is usable.

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

The gap is about 20.3 GB: Hunyuan-A13B-Instruct needs roughly 48.3 GB at Q4_K_M and 32GB RAM Laptop (CPU/iGPU only) leaves only about 28 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 32GB RAM Laptop (CPU/iGPU only) run Hunyuan-A13B-Instruct?

No. Hunyuan-A13B-Instruct needs ~48.3 GB even at Q4_K_M, but 32GB RAM Laptop (CPU/iGPU only) only has ~28 GB usable.

How much memory does Hunyuan-A13B-Instruct need?

32GB RAM Laptop (CPU/iGPU only) 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 Windows?

LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.
