FAQPage Schema
How do I benchmark LLMs across academic benchmarks like MMLU and GSM8K?

To benchmark LLMs across academic benchmarks like MMLU, you can use this harness to run standardized evaluations and obtain reproducible metrics covering 60+ tasks. It enables fair model comparisons by testing local and API-based endpoints.

Can I evaluate local HuggingFace models and API-based endpoints using the same tool?

Yes, you can evaluate local HuggingFace models and API-based endpoints using the same tool. It supports running benchmarks on HuggingFace, vLLM, and API providers to enable consistent model quality comparisons.

What is the best way to get reproducible metrics for LLM evaluation?

The best way to get reproducible metrics for LLM evaluation is running a standardized harness across 60+ academic benchmarks. This approach tracks progression during training and provides comparative reporting against community baselines.

Do I need lm-eval-harness and transformers to run these LLM benchmarks?

Yes, you need lm-eval-harness and transformers to run these LLM benchmarks. The evaluation framework requires these dependencies along with compatible backends to execute tests on local deployments and API providers.

How does benchmarking LLMs with a standardized harness help with model selection?

Benchmarking LLMs with a standardized harness helps model selection by providing reproducible evaluation metrics across tasks like TruthfulQA and HumanEval. This allows research labs to fairly compare model quality and track training progress.

When do I need to run academic benchmarks for my language model?

You need to run academic benchmarks for your language model when you require standardized, reproducible evaluation metrics to compare model quality, track progression during training, or publish comparative results against community baselines.
