Evaluators

Learning Commons • Platform • Docs

Evaluators help you to measure the attributes of LLM-generated text through the lens of learning science:

• Optimize features: Sharpen AI-generated content so it aligns with pedagogy and your goals.
• Maintain performance: Use evaluators as product analytics to confirm LLM output stays on target.
• Select models: Compare candidate models by testing their output against the evaluators.

Quickstart

Check out the Quickstart to start using Evaluators.

Access method	When to use	How to use
Evaluators playground	For a quick demo of how evaluators work	1. Open the Evaluators playground 2. Choose an evaluator family and provide your inputs 3. Click Evaluate, then expand each result for its score and reasoning
SDK	To integrate into your TypeScript or Python project	1. Install: npm install @learning-commons/evaluators or pip install learning-commons-evaluators 2. Import an evaluator, pass your API key, and call evaluate 3. See the TypeScript and Python SDK READMEs for details
Python notebook	For quick prototyping	1. Start Jupyter Lab: jupyter lab (opens at http://localhost:8888) 2. Browse into evals/ and open the evaluator you want to try 3. Copy your text into the last code cell and run it You can also use an IDE with Python and Jupyter support, such as VS Code with Microsoft's Python and Jupyter extensions.
Local	To evaluate inputs locally on your machine	Clone this repository and follow the directions for your platform: - Setup on Mac/Linux - Setup on Windows
