STOP “VIBE TESTING” YOUR LLMS. IT'S TIME FOR REAL EVALS

Summary from the TLDR AI newsletter

Stax is an experimental developer tool designed to streamline the LLM evaluation lifecycle. Evals give developers clear metrics to help understand what's actually better, so developers don't have to waste hours 'vibe testing' every time they try a new model or tweak a prompt. Stax empowers developers to rigorously test their AI stacks to help make data-driven decisions. It allows developers to easily define their own criteria and build a custom autorater.
