Kullback-Leibler Divergence is an Incomplete Metric for Quantization Quality
October 24, 2026
Using static text datasets to calculate KLD between base and quantized models fails to account for the shifting probability distributions present during autoregressive generation. Reliable quantization evaluation requires datasets that mirror the model's own generated context during inference.

researcherYou should avoid using random text benchmarks when evaluating quantization effects on logit distributions.
