Cappy: Small Scorer Boosts Large Multi-Task Language Models

This article from Google Research introduces Cappy, a small scorer designed to improve the performance of large multi-task language models (LLMs) like FLAN and OPT-IML. The article highlights the challenges associated with operating these massive models, including high computational costs and memory requirements. Cappy aims to address these challenges by providing a more efficient way to evaluate and refine the outputs of these LLMs. The focus on instruction-following and task-wise generalization is crucial for advancing NLP capabilities. Further details on Cappy's architecture and performance metrics would strengthen the article.
