OpenAI Evals
Evals is a framework for evaluating LLMs and LLM systems, and an open-source registry of benchmarks.
Overview
OpenAI Evals is an open-source software framework for evaluating the performance of large language models and the systems built with them. It provides a structure for creating 'evals,' which are tests based on specific datasets and evaluation logic. The framework includes a registry of existing benchmarks to allow for easy comparison of different models. While it was created by OpenAI, it is designed to be model-agnostic, enabling developers to test models from any provider or their own custom models. It is a powerful tool for anyone looking to create reproducible and standardized evaluations for LLMs.
