VerifiedUsing quantized versions (such as Q4, Q5) can significantly reduce VRAM usage with minimal performance loss.80% similarVerifiedModern quantization schemes such as GPTQ and AWQ introduce layer-by-layer calibration and error compensation mechanisms to keep perplexity loss within 1–2%77% similarUnverifiedPost-hoc quantization usually causes noticeable performance degradation at small bit widths, whereas QAT simulates quantization errors during training to maintain low-precision output quality.75% similarUnverified量化感知训练（QAT）能将INT8精度损失控制在1%以内72% similarUnverifiedQuantization loss amplifies non-linearly with task complexity: the gap between Q2 and Q8 is small for simple tasks, but low-quantization versions experience a cliff-like performance drop in complex scenarios.72% similar
