# Llama-3.2-1B-Instruct — configuration `c4` (NF4)

Quantized variant used in the *Safety-Aware Configuration-Conditioned LoRA* study.

| field | value |
| --- | --- |
| scheme | `NF4` |
| method | `bitsandbytes` |
| simulated | no — native kernel |
| weight bits | 4 |
| activation bits | 16 |
| group / block size | 64 |
| symmetric | False |
| calibration | none — data-free |
| calibration sha256 | n/a |

The calibration set is **byte-identical across every configuration** so that calibration data cannot be confounded with quantization method. `c2` vs `c3` isolates *method* (GPTQ vs AWQ) at equal bit-width, and is the study's headline control: 0.0276 vs 0.0661 pooled ASR with non-overlapping 95% CIs.
