Nemotron-3-Super-120B-A12B-Uncensored-GGUF
☕ If this model saves you time, buy me a coffee! Every cup fuels more open-weight releases.
⚡ Forged on 8×H200 SXM5 | 1.1TB VRAM
Abliterated (uncensored) GGUF quantizations of NVIDIA's Nemotron-3-Super-120B-A12B.
Guardrails surgically removed via directional abliteration (RepE orthogonal projection) across attention output projections, linear attention output projections, and shared expert MLP layers. Full BF16 precision maintained throughout — no quantized shortcuts.
