The README presents Evals as a framework and registry for testing how language models behave on your use case.

Source: https://github.com/openai/evals

What it supplies: The README presents Evals as a framework and registry for testing how language models behave on your use case.

Useful for: - Run registry evals against a model.
- Write your own model-graded or templated evals.

First action: - Set OPENAI_API_KEY and use Python 3.9 or later.
- Fetch the registry data with Git-LFS.
- Install with pip install evals, or pip install -e . to develop evals.

Prerequisites and limits: Python 3.9 or later and an OpenAI API key; registry data comes through Git-LFS.

- Custom-code evals are not accepted as contributions.
- The workflow depends on an OpenAI API key.

Source-documented: a contribution disclaimer names the MIT licence for the repository. Running evals uses the paid OpenAI API.

Written from the README text only. Statements are as the README gives them; nothing was installed or run.
Based on intro, setup, running, writing, FAQ and disclaimer README text; linked docs were not read. Nothing was installed or run.
