Introducing Langtail 1.0: The Best Way to Test Your AI Apps
The AI space has evolved dramatically over the past 6 months - new frontier models, massive context windows, inexpensive models for certain use cases, and much more.
Notice how fast the feedback loop is between editing your prompt and seeing if the test cases pass. Langtail keeps you in flow and focused on optimizing your prompt for your use case.
At the core of Langtail 1.0 is our new spreadsheet-like interface for testing LLM applications. Our goal was to make it feel natural to anyone used to working in Excel or Google Sheets to build up a set of test cases.
Today we're also launching test configurations. Let's say that a new frontier model gets released and you're wondering if it'll benefit your app. It's as simple as a few clicks to create a new test config with that model and see the side-by-side comparison.
Your prompts can now call tools and have the code run directly within Langtail. It makes prototyping and testing much easier since you no longer have to mock the response. Plus, with our secure sandboxed environment powered by QuickJS, you can safely and quickly execute JavaScript code.
