Frequently Asked Questions

How much VRAM does Huihui Gemma 4 12B Coder Fable5 Composer2.5 V1 Abliterated need?

Huihui Gemma 4 12B Coder Fable5 Composer2.5 V1 Abliterated requires 25.0 GB of VRAM at BF16. Full 262K context adds up to 19.7 GB (44.6 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 12.0B × 16 bits ÷ 8 = 23.9 GB

KV Cache + Overhead ≈ 1.1 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 ≈ 20.8 GB (at full 262K context)
