How to Evaluate Document Extraction

Document extraction is a common use case for LLMs, transforming unstructured text into structured data. It's important to evaluate your extraction pipeline's performance, especially for large-scale or high-stakes applications.
In this video, we walk through how to build a document extraction pipeline and evaluate its performance in generating structured output. You'll learn how to:
Compare the performance of two different models based on latency, cost, and accuracy
Use an LLM judge to evaluate outputs against a ground truth dataset
Run multiple judge repetitions to validate results
