HELMET (How to Evaluate Long-Context Models Effectively and Thoroughly) is introduced as a comprehensive benchmark for evaluating long-context language models (LCLMs), addressing limitations in existing evaluation methods. The blog outlines HELMET's design, key findings from evaluations of 59 recent LCLMs, and offers a quickstart guide for practitioners to utilize HELMET in their research and applications.

Researchers at Ai2 propose a method for evaluating language models by measuring the signal-to-noise ratio (SNR) of benchmarks. They demonstrate that higher SNR in benchmarks leads to more reliable model evaluations and suggest interventions to enhance benchmark quality, ultimately improving decision-making in language model training and scaling predictions. A dataset of 900K evaluation results on 465 models is also released to support further research in evaluation methodologies.
