Item Response Scaling Laws: A Measurement Theory Approach for Efficient and Generalizable Neural Scaling Estimation

ICML 2026poster

Scaling laws provide a fundamental framework for understanding the performance of Large Language Models (LLMs), yet deriving them requires prohibitively expensive evaluations across thousands of checkpoints or millions of inference samples. To address this, we introduce Item Response Scaling Laws (I…

AIR-BENCH 2024: A Safety Benchmark based on Regulation and Policies Specified Risk Categories

ICLR 2025spotlight

Foundation models (FMs) provide societal benefits but also amplify risks. Governments, companies, and researchers have proposed regulatory frameworks, acceptable use policies, and safety benchmarks in response. However, existing public benchmarks often define safety categories based on previous lite…

Fantastic Bugs and Where to Find Them in AI Benchmarks

NeurIPS 2025poster

Benchmarks are pivotal in driving AI progress, and invalid benchmark questions frequently undermine their reliability. Manually identifying and correcting errors among thousands of benchmark questions is not only infeasible but also a critical bottleneck for reliable evaluation. In this work, we int…

Reliable and Efficient Amortized Model-based Evaluation

ICML 2025poster

Comprehensive evaluations of language models (LM) during both development and deployment phases are necessary because these models are thought to possess numerous capabilities as well as safety risks. The average score across a wide range of benchmarks provides a signal that helps guide the use of t…
