Frequently Asked Questions
How much VRAM does Huihui Gemma 4 12B Agentic Fable5 Abliterated need?
Huihui Gemma 4 12B Agentic Fable5 Abliterated 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 Huihui Gemma 4 12B Agentic Fable5 Abliterated?
