Promptfoo

promptfoo is a software tool that allows users to evaluate and improve Language Model (LLM) performance. It enables users to iterate on LLMs more efficiently, measure quality improvements, and identify regressions. With promptfoo, users can create test cases, use representative user inputs for tuning prompts, set up evaluation metrics, compare prompts and model outputs side-by-side, and integrate the library into existing workflows. This software is widely used by LLM apps serving over 10 million users.

Key Features:

1. Faster Iteration: promptfoo facilitates faster iteration on Language Models by providing tools for evaluating their performance.

2. Quality Improvement Measurement: Users can measure the quality improvements of their Language Models using promptfoo's evaluation capabilities.

3. Regression Detection: The software helps catch regressions in Language Model performance so that they can be addressed promptly.

4. Test Case Creation: Users can create a list of test cases to assess the effectiveness of different prompts and models.

5. Representative User Inputs: To reduce subjectivity when tuning prompts, promptfoo allows users to use a representative sample of user inputs.

6. Evaluation Metrics Setup: Users have the option to choose from built-in metrics or define custom metrics for evaluating LLMs.

7. Prompt & Model Comparison: Users can compare different prompts and model outputs side-by-side using promptfoo's visual interface.

8. Integration with Existing Workflows: The software can be seamlessly integrated into existing testing or continuous integration workflows.
