Root Cause

Aggressive quantization causing output quality loss.

generic

Workarounds

  1. 88% success Use 4-bit quantization (GPTQ/AWQ) as balanced tradeoff
  2. 85% success Calibrate with representative dataset for better quantization

Dead Ends

Common approaches that don't work:

  1. Use 2-bit quantization for everything 85% fail

    Severe quality degradation

  2. Skip calibration data during quantization 80% fail

    Poor quantization accuracy
