Project Title

evals — Framework for Evaluating Large Language Models and Open-Source Benchmark Registry

Overview

Evals is an open-source framework designed for evaluating the performance of large language models (LLMs) and systems that incorporate LLMs. It offers a registry of benchmarks to test various aspects of OpenAI models and the flexibility to create custom evaluations tailored to specific use cases. This tool is crucial for developers working with LLMs to understand how different model versions impact their applications without extensive manual testing.

Key Features

Framework for evaluating LLMs and systems built using LLMs
Open-source registry of benchmarks for testing different model dimensions
Ability to create custom evaluations for specific use cases
Option to build private evaluations using proprietary data without public exposure

Use Cases

Developers and researchers needing to assess the performance of LLMs in their applications
Teams looking to compare different model versions to optimize their systems
Individuals wanting to create and run evaluations without exposing sensitive data

Advantages

Simplifies the process of understanding how model versions affect specific use cases
Provides a registry of benchmarks for common evaluation tasks
Allows for the creation of private evaluations, safeguarding sensitive data

Limitations / Considerations

Requires an OpenAI API key and awareness of associated costs
Utilizes Git-LFS for storing the evals registry, which may have additional setup requirements
Custom evaluations require development effort and understanding of the framework

Hugging Face's Transformers: A library of pre-trained models and a framework for developing your own models, differing in its focus on model deployment rather than evaluation.
AllenNLP: An open-source NLP research library, primarily used for building and training custom models, with less emphasis on model evaluation compared to Evals.
