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)
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run Hunyuan A13B Instruct?
Yes, at IQ2_XXS (22.7 GB) or lower. Higher quantizations like IQ2_XS (24.7 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for Hunyuan A13B Instruct?
For Hunyuan A13B Instruct, Q4_K_M (48.8 GB) offers the best balance of quality and VRAM usage. Q4_K_L (49.8 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 22.7 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
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)
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.
