| description.long | A package management system that simplifies the installation, configuration, and deployment of applications in Kubernetes environments. Similar to traditional package managers like apt or homebrew, Helm enables developers to define and manage reusable application packages called Charts across clusters. | A framework for conducting few-shot evaluation of language models against various tasks and benchmarks. Supports multiple model backends, custom evaluation metrics, and extensible task definitions for assessing model capabilities and performance. |
