5. Calibrated Set Maximizes Lexical Diversity
By focusing on the frequency distribution of words, ZipCal effectively captures the sparse "long tail" of vocabulary, ensuring the calibration data is rich and comprehensive without relying on expensive model inference.
ZipCal consistently demonstrates superior or on-par performance compared to current leading methods across various compression techniques (Pruning: Wanda, 2SSP; Quantization: GPTQ, AWQ) and LLMs (Llama-3.1-8B-Instruct, Gemma-2-9B-it).

This demonstrates ZipCal's ability to maintain or exceed the performance quality of existing methods while being significantly more efficient.
A critical advantage of ZipCal is its exceptional speed and scalability, making it practical for the largest LLMs and datasets where model-dependent methods become prohibitively expensive.
~260x Faster
Average Speedup in Data Curation vs. SOTA (COLA)
ZipCal boasts a tractable linear complexity of O(nk) for single-domain and O(mNk) for multi-domain, a stark contrast to the computationally intensive, model-dependent approaches like COLA. This translates to an average speedup of ~260x, reaching up to 1330x faster for larger models and datasets (e.g., Llama-3.1-70B on WinoGrande vs. ARC-C).
This efficiency means data curation, once a bottleneck requiring hours, is reduced to mere seconds, enabling rapid experimentation and deployment in enterprise settings.
ZipCal extends its utility to complex enterprise scenarios by offering a robust multi-domain and multi-lingual sampling strategy, addressing challenges of generalization across diverse tasks and languages.
ZipCal's Robustness Across Diverse Languages & Domains
For models requiring general-purpose or multi-domain calibration, simply concatenating datasets is suboptimal. ZipCal's hierarchical sampling strategy first extracts local representative pools from each domain/language, then applies a greedy k-centers selection to ensure semantic spread.
This approach addresses intra-task sub-optimality, where matching calibration and task domains doesn't always guarantee best performance (e.g., MMLU-ES performs better with Chinese calibration data). Multi-domain ZipCal achieves higher overall average scores and acts as a stabilizer across scenarios, proving more robust than naive language-matching. It ensures a single compressed model can achieve reasonable performance across varied, unforeseen downstream tasks and languages.
