Decision brief

ARES is a Python-based tool for automated evaluation of RAG systems, offering scoring and comparison functionalities.

Good fit when

  • Use ARES when you need to evaluate RAG systems with specific criteria such as context relevance, answer faithfulness, and answer relevance.
  • Consider ARES if you have a human preference validation set of at least 50 annotated query-document-answer triples, and a larger set of unlabeled triples for scoring.

Avoid when

  • Do not use ARES if you lack the necessary human-annotated datasets for evaluation criteria or if you do not have a large set of unlabeled triples for scoring.
  • Avoid ARES if your machine does not meet the requirements, such as having over 100 GB of available disk space and a compatible GPU like the A100.
Requirements:
Requires over 100 GB of available disk space and a compatible GPU like the A100.; Installation of conda and gcc is necessary for setup.
