Frequently Asked Questions

How much VRAM does Hunyuan A13B Instruct need?

Hunyuan A13B Instruct requires 48.8 GB of VRAM at Q4_K_M, or 161.3 GB at BF16. Full 33K context adds up to 4.0 GB (52.8 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 80.4B × 4.8 bits ÷ 8 = 48.2 GB

KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 4.6 GB (at full 33K context)

Can I run Hunyuan A13B Instruct on a Mac?

Yes — Mac Studio M1 Max (32 GB) and 84 other Macs can run Hunyuan A13B Instruct, the smallest at IQ2_S. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 48.8 GB of usable unified memory (RAM minus macOS overhead), from Mac Pro M2 Ultra (64 GB).

Can I run Hunyuan A13B Instruct locally?

Yes — Hunyuan A13B Instruct can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Hunyuan A13B Instruct?

At Q4_K_M, Hunyuan A13B Instruct can reach ~125 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)

Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.

Example: NVIDIA B200 → 7.7 GB active ÷ (8000 × 0.65) = 1.49 ms, plus 32 layers × 0.055 ms = 1.76 ms, so 1000 ÷ 3.25 ms = ~308 tok/s

Estimated speed at Q4_K_M (48.8 GB)

~308 tok/s
~308 tok/s
~239 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.

What's the download size of Hunyuan A13B Instruct?

At Q4_K_M, the download is about 48.24 GB. The full-precision BF16 version is 160.79 GB. The smallest option (IQ2_XXS) is 22.11 GB.

Which GPUs can run Hunyuan A13B Instruct?

No single consumer GPU has enough VRAM to run Hunyuan A13B Instruct at Q4_K_M (48.8 GB). Multi-GPU or professional hardware is required.

Which devices can run Hunyuan A13B Instruct?

52 devices with unified memory can run Hunyuan A13B Instruct at Q4_K_M (48.8 GB), including ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB), GMKtec EVO-X2 (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
