Decision brief

Lighteval is designed for evaluating language models across multiple backends. It integrates well with Hugging Face and provides a wide range of extras, making it particularly handy in non-Windows environments.

Good fit when

When you need to evaluate the performance of various LLMs on different backend infrastructures, especially if you are working within Mac/Linux environments.
If your evaluation process involves pushing results to the Hugging Face Hub and integrating with its ecosystem.

Avoid when

Avoid Lighteval for evaluations on Windows systems as it is currently untested and not supported there.
Should you require a solution that does not integrate with or depend on the Hugging Face ecosystem, Lighteval might not fulfill your needs.
