Frequently Asked Questions
How much VRAM does Humanizer Gemma 4 E4b need?
Humanizer Gemma 4 E4b requires 5.3 GB of VRAM at Q4_K_M, or 16.4 GB at BF16. Full 131K context adds up to 2.9 GB (8.2 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 7.9B × 4.8 bits ÷ 8 = 4.8 GB
KV Cache + Overhead ≈ 0.5 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 ≈ 3.4 GB (at full 131K context)
VRAM usage by quantization
What's the best quantization for Humanizer Gemma 4 E4b?
For Humanizer Gemma 4 E4b, Q4_K_M (5.3 GB) offers the best balance of quality and VRAM usage. Q5_K_M (6.2 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 3.9 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Humanizer Gemma 4 E4b on a Mac?
Yes — Mac Mini M2 (8 GB) and 145 other Macs can run Humanizer Gemma 4 E4b, the smallest at Q2_K. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 5.3 GB of usable unified memory (RAM minus macOS overhead), from Mac Mini M2 Pro (16 GB).
Can I run Humanizer Gemma 4 E4b locally?
Yes — Humanizer Gemma 4 E4b can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Humanizer Gemma 4 E4b?
At Q4_K_M, Humanizer Gemma 4 E4b can reach ~909 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~124 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 ÷ 5.28 × 0.65 = ~985 tok/s
Estimated speed at Q4_K_M (5.3 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Humanizer Gemma 4 E4b?
At Q4_K_M, the download is about 4.76 GB. The full-precision BF16 version is 15.88 GB. The smallest option (Q2_K) is 3.37 GB.
