Granite 4.2 3B — Heretic NX PRIME (GGUF)

GGUF release of a capability-preserving residual-stream edit of

ibm-granite/granite-4.2-3b.

This is the beta 2.4, rank-16 protected candidate selected on a fixed

refusal/KL frontier and validated independently after materialization.

This is a static weight edit, not a LoRA and not a fine-tune. No adapter or

custom runtime hook is required.

Files

| File | Size | Recommended use |

|---|---:|---|

| Granite-4.2-3B-Heretic-NX-PRIME-BF16.gguf | 6.82 GiB | Maximum fidelity |

| Granite-4.2-3B-Heretic-NX-PRIME-Q8_0.gguf | 3.63 GiB | Near-BF16 quality; recommended |

| Granite-4.2-3B-Heretic-NX-PRIME-Q4_K_M.gguf | 2.09 GiB | Smallest practical LM Studio build |

All three files contain the Granite tokenizer and chat template and were

smoke-tested with llama.cpp b10621.

Evaluation

| Evaluation | Official base | Heretic NX PRIME beta 2.4 |

|---|---:|---:|

| Explicit-refusal marker proxy | 103 / 104 | 0 / 104 |

| Paired MCQ capability slice | 63.35% | 64.29% |

| Capability rows | 854 | 854 |

| Capability non-inferiority margin | — | passed at -3% |

The paired capability slice contains ARC-Challenge, HellaSwag and MMLU. Its

bootstrap mean difference is +0.94 percentage point, with a 95% interval

of [-0.35, +2.22] points.

KL depends on the exact runtime being measured:

| KL protocol | beta 2.4 |

|---|---:|

| NF4 base with activation-native residual hooks | 0.024674 |

| Static BF16 checkpoint, base and candidate quantized independently to NF4 | 0.042418 |

The second value includes independent NF4 quantization noise and should not be

presented as a pure BF16-to-BF16 KL measurement. The GGUF quantizations were

load-tested, but their full 104-row behavioral scores are not claimed to be

identical to the BF16 checkpoint.

The 104-row refusal result is a lexical explicit-refusal proxy. It is not a

measure of semantic task success and is not a universal model-quality score.

See EVALUATION_SUMMARY.md and the included JSON

reports for the exact protocols.

LM Studio

Download one GGUF file and place it in your LM Studio models directory. Q8_0

is the default recommendation; Q4_K_M is appropriate when RAM/VRAM is tight.

hf download 0xzknw/Granite-4.2-3B-Heretic-NX-PRIME-GGUF Granite-4.2-3B-Heretic-NX-PRIME-Q8_0.gguf --local-dir "$env:USERPROFILE\.lmstudio\models\0xzknw\Granite-4.2-3B-Heretic-NX-PRIME-GGUF"

If LM Studio is already open, refresh the model list or restart the app after

the download completes.
