  "title": "DualQuant: Dual-scale Calibration-free Weight-and-Activation Quantization for LLMs",
  "summary": "DUALQUANT replaces calibration-data-dependent activation quantization (e.g., SmoothQuant) and weight-only quantization with a calibration-free dual-scale method derived from weight-reconstruction MSE minimization, supporting MX and NVFP4 block formats. It costs the engineering effort of integrating a packed W4A4 kernel path and incurs some accuracy degradation relative to BF16, though the reported solver has closed-form updates and no calibration pipeline to maintain. It can fail on workloads whose accuracy tolerance is tighter than WikiText-2/C4 zero-shot benchmarks suggest, on models outside the evaluated Llama/Qwen families, and where native 4-bit hardware or mature W4A4 kernels are unavailable.",
  "rationale": "The method runs on the reader's exact hardware class (single 24 GB GPU) with a validated real-kernel speedup and no calibration data requirement, but W4A4 activation quantization quality is workload-sensitive and should be validated on the reader's own tasks before production adoption.",
