OpenCompass is a Python-based evaluation platform and toolkit for benchmarking large language models across 100+ datasets, supporting models like Llama3, Mistral, Qwen, GPT-4, and Claude. It provides configurable evaluation pipelines, leaderboards (CompassRank), and a benchmark hub for comparing LLM quality.

Use cases

• evaluate llm performance across benchmarks
• compare open-source and proprietary language models
• run standardized llm evaluation suites
• benchmark my fine-tuned model on mmlu and other datasets
• build an llm leaderboard
• test chatgpt-style models on nlp tasks

When to choose

• you need reproducible, large-scale LLM benchmarking across many datasets
• you want to compare heterogeneous models (OpenAI APIs, HuggingFace checkpoints) under one framework
• you need a maintained, widely-adopted evaluation toolkit with an active community

When to avoid

• you only need quick ad-hoc prompt testing rather than systematic benchmarking
• you need evaluation of non-text modalities like images or audio
• you want a hosted no-setup evaluation service rather than a self-run framework
