What is EleutherAI's lm-evaluation-harness?
mediumAnswer
- Open-source library for running standardized LLM evals against 200+ benchmarks (MMLU, HellaSwag, GSM8K, ARC, TruthfulQA, ...) with consistent prompts, few-shot settings, and scoring rules.
- Standardizes reported scores across the community — critical because two labs' MMLU numbers can differ 5% due to prompt / normalization differences.
- Used to run the HuggingFace Open LLM Leaderboard.
- Also supports vLLM / HF Transformers / OpenAI backends.
- Essential tool for reproducible LLM evaluation.
