## Adoption goal

Lighteval is designed for evaluating language models across multiple backends. It integrates well with Hugging Face and provides a wide range of extras, making it particularly handy in non-Windows environments.

## ⚡️ Installation

> **Note**: lighteval is currently *completely untested on Windows*, and we don't support it yet. (*Should be fully functional on Mac/Linux*)

```bash
pip install lighteval
```

Lighteval allows for *many extras* when installing, see [here](https://huggingface.co/docs/lighteval/installation) for a **complete list**.

If you want to push results to the **Hugging Face Hub**, add your access token as
an environment variable:

```shell
hf auth login
```
