quantfit v0.1.0
GPU-aware quantization CLI with a built-in safety-tax check.
- verify-safety — does the quantized model still refuse what the fp16 baseline refused? A two-axis tax (refusal-robustness vs over-refusal), per-zone, local judge, curated public probes. Validated on qwen2.5-1.5b + llama-3.2-1b AWQ (0 harmful-compliance regressions on both).
- Quantize — awq / gptq / smoothquant / fp8 / rtn (compressed-tensors) + GGUF, one frozen packed calibration.
- GPU-aware 3-tier capacity: in-GPU / CPU-offload / refuse.
- Commands: check / list / quantize / verify / verify-safety. Tested on Python 3.10–3.13.
