"description": "INT4 weight-only quantization (W4A16) for diffusion models via torchao. Activations remain FP16 — zero quantization quality loss. Full LoRA support: standard + LoKr format compatible, multi-LoRA stack (≤5), IS_CHANGED fingerprint skip (0s repeat generation), SHA256 JSON disk cache (<1s hit), GPU pre-hook bake-in. Supports Intel Arc XPU, NVIDIA CUDA, AMD ROCm. Verified on Krea2 Turbo, Flux2 Klein 9B, Z-Image, Boogu. Includes model analysis CLI. Requires: pip install torchao>=0.17.0"
