SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Provides a reproducible, standardized way to evaluate and compare large language models across academic and industry benchmarks so teams can measure model quality, track training progress, and report results consistently.

Core Features & Use Cases

  • Standardized Benchmarks: Run 60+ tasks including MMLU, GSM8K, HumanEval, HellaSwag, TruthfulQA, ARC, and more with consistent prompts and metrics.
  • Multi-backend Support: Evaluate models via HuggingFace, vLLM, and API-based providers for local and remote model comparisons.
  • Research & Production Workflows: Use for paper baselines, model comparisons across checkpoints, automated periodic evaluation, and distributed/multi-GPU runs with exportable JSON results.

Quick Start

Evaluate meta-llama/Llama-2-7b-hf on MMLU, GSM8K, and HellaSwag and save the output to results/ using the lm-eval harness.

FAQPage Schema
How do I evaluate large language models on standardized academic benchmarks?

You can evaluate large language models on standardized academic benchmarks by applying consistent prompts and metrics to tasks like MMLU, GSM8K, and HumanEval. This supports reproducible few-shot and zero-shot evaluations across local and remote models.

What is the best way to compare LLM performance across multiple checkpoints?

Comparing LLM performance across checkpoints involves running multi-model evaluations on standardized tasks and exporting the results to JSON. This allows teams to measure model quality and track training progress consistently over time.

Can I use vLLM and HuggingFace backends for batched LLM evaluations?

Yes, you can use vLLM and HuggingFace backends to run batched LLM evaluations for local models. The system also supports distributed multi-GPU configurations and API-based providers for evaluating remote models.

Does the lm-eval harness support zero-shot and few-shot testing for research papers?

Yes, the lm-eval harness supports reproducible zero-shot and few-shot testing to establish research paper baselines. It provides standardized evaluation across 60+ tasks including TruthfulQA, ARC, and HellaSwag to ensure consistent reporting.

How do I export LLM benchmark results to JSON for automated reporting?

You export LLM benchmark results to JSON by completing the evaluation runs across the specified tasks. The output provides standardized metrics suitable for automated periodic evaluation and consistent quality tracking.
