Frequently Asked Questions
- How much VRAM does SuperGemma 4 12B Abliterated need?
SuperGemma 4 12B Abliterated requires 8.2 GB of VRAM at Q4_K_M, or 25.0 GB at BF16. Full 262K context adds up to 95.9 GB (104.1 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)
KV Cache + Overhead ≈ 96.9 GB (at full 262K context)
VRAM usage by quantization
Q4_K_M8.2 GBQ4_K_M + full context104.1 GB- Can NVIDIA GeForce RTX 4090 run SuperGemma 4 12B Abliterated?
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 SuperGemma 4 12B Abliterated?
