Langtail 1.0 – Spreadsheet-like interface for testing LLM apps

We've been using Langtail at Deepnote for over a year now and would highly recommend it to any team serious about shipping AI products. The ROI has been clear from day one.

I’m one of the engineers on this project. Our team has thought deeply (and talked to other companies much larger than us) about testing LLM-based apps. AMA.

Great guys!
