Analyzing LLMs Made Easy with promptfoo

If you're into creating and fine-tuning Large Language Models (LLMs), you know how challenging and time-consuming it can be to measure their quality improvements and detect regressions. Luckily, there's a new AI-powered tool called promptfoo that takes the hassle out of this process, allowing you to iterate on LLMs faster and more efficiently.

How It Works

Using promptfoo is as simple as 1-2-3. Here's a quick breakdown of how this tool operates:

1. Create a list of test cases: Gather a representative sample of user inputs to help reduce subjectivity when fine-tuning prompts.

2. Set up evaluation metrics: Utilize built-in metrics, LLM-graded evaluations, or define your own custom metrics to ensure accurate assessments.

3. Select the best prompt & model: Compare prompts and model outputs side-by-side, or seamlessly integrate the promptfoo library into your existing test/CI workflow.

Integrating into Your Workflow

The flexibility of promptfoo allows you to mold it into your existing workflow seamlessly. Whether you prefer using the web viewer or the command line, promptfoo has got you covered.

The tool is already trusted by LLM apps serving over 10 million users, proving its reliability and efficiency in the real world.

Documentation & Privacy

In the promptfoo documentation, you'll find detailed guides on running benchmarks, evaluating factuality, evaluating RAGs, and minimizing hallucinations. Additionally, the tool is equipped with a privacy policy that respects user data and confidentiality.

Pros and Cons of promptfoo

Pros

• Simplifies the process of iterating on Large Language Models.
• Offers a range of evaluation metrics for accurate assessments.
• Can be integrated seamlessly into existing workflows.

Cons

• Limited information on specific use cases and success stories.
