Frequently Asked Questions
How much VRAM does Huginn 0125 need?
Huginn 0125 requires 8.6 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 3.9B × 16 bits ÷ 8 = 7.8 GB
KV Cache + Overhead ≈ 0.8 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.
VRAM usage by quantization
Can I run Huginn 0125 on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Huginn 0125. Apple Silicon uses unified memory, so the model shares RAM with the system. At BF16 you need at least 8.6 GB of usable unified memory (RAM minus macOS overhead).
Can I run Huginn 0125 locally?
Yes — Huginn 0125 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Huginn 0125?
At BF16, Huginn 0125 can reach ~558 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~76 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 ÷ 8.61 × 0.65 = ~604 tok/s
Estimated speed at BF16 (8.6 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Huginn 0125?
At BF16, the download is about 7.82 GB.
Which GPUs can run Huginn 0125?
40 consumer GPUs can run Huginn 0125 at BF16. Top options include AMD Radeon RX 6800, AMD Radeon RX 6800 XT, AMD Radeon RX 6900 XT, AMD Radeon RX 6700 XT. 26 GPUs have plenty of headroom for comfortable inference.
Which devices can run Huginn 0125?
150 devices with unified memory can run Huginn 0125 at BF16 (8.6 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (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.
