OpenCompass Project Overview
OpenCompass is a comprehensive, state-of-the-art platform designed for the evaluation and benchmarking of large language models. Like a trusty compass for explorers, OpenCompass provides a clear pathway through the intricate terrain of natural language processing (NLP) model evaluation, offering tools to measure their quality and effectiveness with precision and ease.
Key Features of OpenCompass
Model and Dataset Support
OpenCompass is built to support over 20 models from HuggingFace and APIs, and 70+ datasets, covering a wide variety of tests with approximately 400,000 questions. This extensive support allows for comprehensive evaluation in key areas such as language understanding, knowledge-based query, reasoning abilities, and domain-specific exams.
Efficient Distributed Evaluation
This platform enables distributed task execution, allowing evaluations to be completed efficiently and effectively, even for models of scale reaching billions of parameters. This is achieved via a straightforward command facilitating task division, ensuring robust performance checks within a brief period.
Diverse Evaluation Paradigms
OpenCompass supports different evaluation strategies, including zero-shot, few-shot, and chain-of-thought methodologies. These paradigms can be coupled with standard or dialog-style prompts, maximizing the performance extraction from diverse model types.
Modular and Extensible Design
The project encompasses a highly modular design, welcoming easy extensions. Users can integrate new datasets, personalize task strategies, and support alternative cluster management systems. It enables researchers and developers to easily tailor the toolkit according to their specific requirements.
Experiment Management and Reporting
OpenCompass ensures experiments are meticulously recorded through configuration files, with real-time reporting mechanisms to track and analyze results efficiently.
Recent Updates
- Support for OpenAI's multilingual QA dataset MMMLU and Qwen models across various backends.
- Implementation of answer extraction via model post-processing, with xFinder as the initial model.
- Introduction of new evaluation benchmarks like SciCode and RULER, enhancing model assessment capabilities in research coding and long-context language processing.
Installation and Getting Started
Setting up OpenCompass is straightforward with a recommended python environment managed by conda. Users can easily install OpenCompass via pip or build from source to access the latest features and developments.
Steps include:
- Creating a virtual environment and activating it.
- Installing OpenCompass using pip with options for full installations, specific dataset support, or acceleration frameworks.
For dataset preparations, options range from offline downloads to automatic fetching from OpenCompass or ModelScope, catering to various setup preferences.
Evaluation Techniques
Once installed, OpenCompass allows users to craft detailed evaluations using CLI commands or Python scripts. It seamlessly incorporates API and custom models into assessments, supporting accelerated evaluation using backend services like LMDeploy and vLLM.
OpenCompass provides versatility in model evaluation, with configurations for a range of available models and datasets. Users can also manage evaluations across multiple GPUs for enhanced performance.
OpenCompass 2.0
The latest OpenCompass 2.0 enhances usability with three core components:
- CompassKit: A robust set of tools for LLM and Vision-language models.
- CompassHub: An innovative benchmark browser for streamlined access and utilization.
- CompassRank: Improved leaderboards integrating both open-source and proprietary benchmarks for comprehensive industry evaluations.
