Frequently Asked Questions
How much VRAM does Gemma4 12B QAT Uncensored HauhauCS Balanced need?
Gemma4 12B QAT Uncensored HauhauCS Balanced requires 7.9 GB of VRAM at Q4_K_M, or 26.4 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 12B × 4.8 bits ÷ 8 = 7.2 GB
KV Cache + Overhead ≈ 0.7 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 NVIDIA GeForce RTX 4090 run Gemma4 12B QAT Uncensored HauhauCS Balanced?
Yes, at Q8_0 (13.2 GB) or lower. Higher quantizations like BF16 (26.4 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for Gemma4 12B QAT Uncensored HauhauCS Balanced?
For Gemma4 12B QAT Uncensored HauhauCS Balanced, Q4_K_M (7.9 GB) offers the best balance of quality and VRAM usage. Q5_K_M (9.4 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 5.6 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Gemma4 12B QAT Uncensored HauhauCS Balanced on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Gemma4 12B QAT Uncensored HauhauCS Balanced. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 7.9 GB of usable unified memory (RAM minus macOS overhead).
