# Score model outputs with reusable evaluator prompts and metrics using autoevals

Apply reusable evaluators to model outputs when you need lightweight scoring, rationale capture, or quick eval loops in code.

## Prerequisites

Python or Node.js, access to an OpenAI-compatible model endpoint or Braintrust proxy

## Installation

Use the upstream install or setup path that matches your environment:
