Frequently Asked Questions
How much VRAM does Hunyuan 7B Instruct need?
Hunyuan 7B Instruct requires 5.1 GB of VRAM at Q4_K_M, or 15.6 GB at BF16. Full 33K context adds up to 4.0 GB (9.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 7.5B × 4.8 bits ÷ 8 = 4.5 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
What's the best quantization for Hunyuan 7B Instruct?
For Hunyuan 7B Instruct, Q4_K_M (5.1 GB) offers the best balance of quality and VRAM usage. Q4_K_L (5.2 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 2.6 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Hunyuan 7B Instruct on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Hunyuan 7B Instruct. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 5.1 GB of usable unified memory (RAM minus macOS overhead).
Can I run Hunyuan 7B Instruct locally?
Yes — Hunyuan 7B Instruct can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Hunyuan 7B Instruct?
At Q4_K_M, Hunyuan 7B Instruct can reach ~947 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~129 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 5.07 × 0.65 = ~1026 tok/s
Estimated speed at Q4_K_M (5.1 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Hunyuan 7B Instruct?
At Q4_K_M, the download is about 4.50 GB. The full-precision BF16 version is 15.01 GB. The smallest option (IQ2_XXS) is 2.06 GB.
