arXiv:2606.22826v2 Announce Type: replace Abstract: Evaluating LLMs across many model variants---quantized, fine-tuned, or deployment-specific---requires running large benchmarks repeatedly, a process that can take tens of hours per model on edge hardware such as NPUs. Existing subset selection methods reduce this cost but depend on large calibration pools or learned prediction layers. We introduce MINCE (Monte Carlo Informed N-sizing for Compact Evaluation), which uses Monte Carlo simulation over per-item logs from a small set of calibration models to find the minimum subset size that bounds accuracy drift and then fixes a randomly sampled subset at that size, with no prediction layer needed. MINCE reduces IFEVAL by 54%, MMLU by 89%, GSM8K by 70%, and MMLU-Pro by 88% with maximum drift leq2.62,pp on BF16 calibration models. The frozen subsets generalize to held-out GPU models with mean drift leq1.40,pp and to INT4 NPU models with mean drift of 0.77--3.59,pp, while delivering evaluation speedups of up to 8.1imes on the GPU models and evaluation speedups of 1.7--3.4imes on the NPU models. The method is robust to calibration pool size and achieves lower drift than tinyBenchmarks (12imes lower on MMLU, 3.3imes on GSM8K) while using 42imes fewer calibration models.
