-    "Internally, we recommend using promptfoo.  It's open source, fully-featured, and easy to use. It's the tool our own Solutions Architect team prefers to use for their evaluations.  Promptfoo offers a streamlined, out-of-the-box solution that can significantly reduce the time and effort required for comprehensive prompt testing. It provides a simple, ready-made infrastructure for batch testing, version control, and performance analytics, allowing developers to focus more on refining their prompts rather than building and maintaining testing frameworks. It makes it easy to run evaluations across multiple prompts, models, and providers, and it also provides tools to easily visualize and compare evaluation results. It's a huge improvement over trying to write your own evaluation logic from scratch!\n",
