How to Use PromptPerf
Install PromptPerf: Install PromptPerf using npx, npm, or brew by running the installation command in your terminal
Create Configuration File: Set up a YAML configuration file (promptfooconfig.yaml) that defines your prompts, providers (AI models), and test cases
Define Prompts: Add your prompts either as text files or directly in the config file. You can separate multiple prompts using '---' or use separate files for each prompt
Configure Providers: Specify which AI models you want to test (e.g., OpenAI, Anthropic, Google) in the providers section of your config file
Create Test Cases: Define test scenarios with different input variables and expected outputs that your prompts should handle correctly
Add Assertions (Optional): Set up requirements and conditions that the outputs should meet, which will be checked automatically during evaluation
Run Evaluation: Execute the evaluation by running 'npx promptfoo eval' command in your terminal
Review Results: Open the web viewer to analyze the outputs, compare results across different models, and review the similarity scores
Export Data: Export your evaluation results in JSON or CSV format for further analysis or documentation
Iterate and Improve: Based on the evaluation results, refine your prompts and re-run tests to measure improvements
PromptPerf FAQs
PromptPerf is a tool designed to help test and optimize AI prompts by evaluating them against multiple test cases and measuring output similarity. It helps users stop guessing which AI model and settings work best for their prompts by providing data-driven insights.
