SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Benchmarks LLMs across 60+ academic tasks to enable objective comparisons, progress tracking, and publication-ready reporting across model families and backends.

Core Features & Use Cases

  • Standardized evaluation across core tasks (MMLU, HumanEval, GSM8K, TruthfulQA, HellaSwag, ARC) using a single harness.
  • Supports multiple backends (HuggingFace, vLLM, and API-compatible endpoints) to integrate into ML pipelines for benchmarking model quality and progress tracking.
  • Provides reproducible reports suitable for research papers and internal model comparisons.

Quick Start

Run an end-to-end evaluation with a chosen model and tasks using the harness to generate a results JSON.
