What is Promptfoo?
Promptfoo is a command-line interface (CLI) and library that helps improve the evaluation and security of large language model (LLM) applications. It allows users to create effective prompts, configure models, and build retrieval-augmented generation (RAG) systems using specific benchmarks for different use cases.
Key Features:
- Automated Security Testing: Supports red teaming and penetration testing to ensure application security.
- Faster Evaluations: Utilizes caching, concurrency, and live reloading for quicker results.
- Custom Metrics: Offers automated scoring through customizable evaluation metrics.
- Wide Compatibility: Works with various platforms and APIs like OpenAI, Anthropic, and HuggingFace.
- CI/CD Integration: Easily fits into continuous integration and deployment workflows.
Benefits of Using Promptfoo
Promptfoo is designed for developers, providing:
- User-Friendly Experience: Fast processing and features like live reloading and caching.
- Collaboration Tools: Built-in sharing and a web viewer to facilitate teamwork.
- Open-Source and Privacy-Focused: Operates locally to secure user data while interacting directly with LLMs.
How to Get Started
Getting started with Promptfoo is easy:
- Run npx promptfoo@latest init to set up a YAML configuration file.
- Edit the YAML file to write the prompt you want to test, using double curly braces for variables.
- Add model providers and specify the models to test.
- Include example inputs and optional assertions for output requirements.
- Run the evaluation to test all prompts and models, then review results in the web viewer.
Enhancing Dataset Quality
Promptfoo improves the quality of LLM evaluations by allowing users to create diverse datasets. Use the promptfoo generate dataset command to:
- Combine existing prompts and test cases for unique evaluations.
- Customize dataset generation to fit different evaluation needs.
Securing RAG Applications
Promptfoo also focuses on securing retrieval-augmented generation (RAG) applications against vulnerabilities:
- Detecting Vulnerabilities: Identifies issues like prompt injection that can lead to unauthorized actions.
- Preventing Data Poisoning: Addresses harmful information that can distort outputs.
- Handling Context Window Overflow: Provides custom policies to maintain response accuracy.
Conclusion
In summary, Promptfoo is a powerful CLI tool for testing, securing, and optimizing LLM applications. It supports developers in creating strong prompts, integrating with various LLM providers, and conducting automated evaluations. With its open-source nature, local execution, and collaborative features, Promptfoo enhances data privacy and improves evaluation accuracy. It also fortifies RAG applications against potential attacks, making it a comprehensive solution for secure LLM deployment.
