FAQPage Schema
How do I benchmark LLMs using the lm-evaluation-harness?

Standardized LLM benchmarking uses a unified interface to run tasks like MMLU or GSM8K across HuggingFace, vLLM, and API-based providers. It targets model comparison, progress tracking, and reproducible reporting for academic and industry audiences.

Can I evaluate models served by vLLM or OpenAI APIs?

Yes, LLM evaluation supports multiple backends including HuggingFace, vLLM, and API-based providers like OpenAI. This allows you to integrate and benchmark locally served or remote API models within a reproducible pipeline.

What benchmarks are available for evaluating language model reasoning?

Evaluating language model reasoning includes 60+ benchmarks like MMLU, GSM8K, HumanEval, TruthfulQA, and HellaSwag. These cover language understanding, coding, and reasoning tasks to comprehensively test model capabilities.

Do I need a specific environment to run model comparison benchmarks?

Running model comparison benchmarks requires the lm-evaluation-harness toolkit and a Python ML ecosystem on Linux or macOS. You need this environment setup to support multiple backends via a unified interface.

How does reproducible LLM reporting work for model comparison?

Reproducible LLM reporting works by executing standardized evaluation tasks across supported backends via a unified interface. This generates consistent results files for publication-ready reporting, enabling accurate model comparison and progress tracking.
