Introducing HELMET: Holistically Evaluating Long-context Language Models

HELMET is a new evaluation framework designed to assess long-context language models across multiple dimensions, including coherence, relevance, and factual accuracy. It incorporates a set of benchmark tasks that specifically target the unique capabilities of models handling extended contexts, facilitating a more comprehensive understanding of their performance. This framework is significant for practitioners as it provides a standardized method to evaluate and compare long-context models, ensuring better alignment with real-world applications.
