Frequently Asked Questions
How much VRAM does Humanizer need?
Humanizer requires 8.2 GB of VRAM at Q4_K_M, or 25.0 GB at BF16. Full 262K context adds up to 19.7 GB (27.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 12.0B × 4.8 bits ÷ 8 = 7.2 GB
KV Cache + Overhead ≈ 1 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 ≈ 20.7 GB (at full 262K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run Humanizer?
Yes, at Q8_0 (13.0 GB) or lower. Higher quantizations like BF16 (25.0 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for Humanizer?
For Humanizer, Q4_K_M (8.2 GB) offers the best balance of quality and VRAM usage. Q5_K_S (9.3 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 4.3 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Humanizer on a Mac?
Yes, but only at lower quantizations. The smallest Mac that can run Humanizer is Mac Mini M1 (8 GB) at IQ2_XXS; 156 of the 156 Macs we list can run it at some quantization. For Q4_K_M (8.2 GB) you need a Mac with more unified memory.
Can I run Humanizer locally?
Yes — Humanizer can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Humanizer?
At Q4_K_M, Humanizer can reach ~583 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~80 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 ÷ 8.23 × 0.65 = ~632 tok/s
Estimated speed at Q4_K_M (8.2 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Humanizer?
At Q4_K_M, the download is about 7.18 GB. The full-precision BF16 version is 23.92 GB. The smallest option (IQ2_XXS) is 3.29 GB.
Which GPUs can run Humanizer?
40 consumer GPUs can run Humanizer at Q4_K_M. 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 Humanizer?
155 devices with unified memory can run Humanizer at Q4_K_M (8.2 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Asus ROG Flow Z13 (2025, Ryzen AI Max+ 395, 128 GB), Beelink GTR9 Pro (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.
